Image:43. DNUG 1. + 2. June in Hamburg




Hi and good morning!

This will be my first blog entry in Germany and it's about German about our German "Notes" User Group "DNUG"...


Bei der DNUG hat sich einiges getan in den letzten Monaten! Seitdem die DNUG einen neuen Vorstand hat, werden einige Dinge anders angegangen und auch die Art und Weise, wie die DNUG Konferenz geplant wird, hat sich geändert.

Die Geschäfts-Stelle ist jetzt virtuell und auch die Server der DNUG sind entsprechend virtualisiert. Aber auch an anderen Stellen sieht man, daß sich einiges verändert.

Für die Organisation der Konferenz-Tracks sind die verschiedenen Fachgruppen verantwortlich.

Zur Anmeldung für die Konferenz und für den Schedule werden Tools verwendet, die es günstig aus der Cloud auf dem Markt gibt. Die eigene EULUC Connections Platform der DNUG wandert in die IBM Cloud.


Als Mitglied in der Fachgruppe Verse/Notes/Domino zusammen mit Anett Hammerschmidt und Manfred Lenz als Ansprechpartner und Mitglied in unserer Fachgruppe, haben wir uns um unseren "Track" gekümmert.

Und ich denke sowohl in unserem als auch in allen anderen Tracks findet Ihr spannende Vorträge.

Besonders ans Herz legen möchte ich Euch die Session zum Thema Verse on Premise
(http://sched.co/72CJ) und die Session zum Thema Microsoft und IBM (Link http://sched.co/6zNW).
Aber auch die Lizenz-Session
(http://sched.co/6zJt), die wir in ähnlicher Form schon auf dem Domino Day hatten, wird bestimmt wieder interessant und wichtig mit vielen Diskussionen (im Bereich Lizenzierung, gibt es viele Details, die oft nicht bei Kunden und auch Business Partnern bekannt sind).

Relativ neu ist auch bei der DNUG, daß IBM alle Fachgruppen mit einem Ansprechpartner unterstützt. Und für unseren Track und auch für andere Tracks stehen die Sprecher die übrige Zeit auf der Konferenz für Fragen zur Verfügung.

Nutzt diese Gelegenheit um die Kollegen von IBM mit Fragen zu löchern und Feedback zu geben über das Produkt, Support und andere Dinge, die Ihr auf dem Herzen habt.


Und auch preislich hat sich bei der DNUG in Bezug auf die Konferenz einiges getan. Die DNUG Konferenz ist für Mitglieder ein ganzes Stück günstiger geworden und auch die Referenten erhalten als Dank für ihren inhaltlichen Beitrag wieder eine kostenlose Konferenzteilnahme.

Ich kann leider selbst dieses Jahr nicht mit auf der Konferenz dabei sein. Mein Urlaub war nicht mehr anders zu planen (das ist eine längere Geschichte).
Aber ich wünsche allen eine tolle und erfolgreiche DNUG Konferenz in neuer Gestalt!!
Ich wäre sehr gerne in Hamburg dabei. Dafür werde ich aber auf jeden Fall beim nächsten Domino Day der Fachgruppe Verse/Notes/Domino im Herbst wieder mit dabei sein.


Für Themen und Vortragsideen und andere Dinge, um die wir uns als Fachgruppe beschäftigen sollen/wollen sind wir immer an Feedback und Mitarbeit interessiert.

Und wer noch nicht auf der DNUG Konferenz angemeldet ist hier nochmal der Link zur Konferenz-Seite

Ciao und bis bald!

Domino 9.0.1 FP6

Daniel Nashed  22 May 2016 21:55:43
Domino 9.0.1 FP6 has been released a while ago. I have installed it and I got positive feedback from customers already.

FP6 contains all the fixes from previous IFs and also the updated JVM Java60SR16FP20 which addresses a couple of security fixes.
Also the server controller interoperability issue is fixed. But for a client based connection you also need to update your admin client!

All the TLS fixes are also included and there is an additional fix for an issue in a TLS handshake.

SPR# MKINA3SPYN - Fixes an intermittent Domino Server crash in crypto code when VerifyMAC() is passed a bogus length.


There are many other potential crash issues and security issues that have been also fixed.
So it makes a lot of sense to install it on Server side.


In additional there are fixes that need notes.ini parameters.

The first fix is to bring back the pre Domino 9 behaviour for removing documents from the trash folder after the threshold expiered.
In Domino 8.5.x was checked on database open. With Domino 9 it is only checked with updall.

There is a new notes.ini parameter CHECK_EXPIRED_SOFT_DELETES_ON_DBOPEN=1 which brings back the previous behaviour.

SPR# HYYH9DF5GR - Fixes situation where emails in trash are not  removed even if "Permanently delete documents after X hours" is set. This fix introduced a new Notes.ini CHECK_EXPIRED_SOFT_DELETES_ON_DBOPEN=1. This is off be default.


There is also an ID-Vault fix which needs a notes.ini parameter. The notes.ini parameter is missing in the SPR description.

The fix introduced needs the this notes.ini parameter IDV_RefreshCerts=1
By default the parameter is disabled for performance reasons. You should only enable it when you are in a key-rollover project.

SPR# KLYH9ZDQNC -- IDVault Key Rollover State Can Be Incorrect Due to Timing Issue

Domino Federarted Web Login / SAML with F5 and ADFS 3.0

Daniel Nashed  25 April 2016 17:14:43

In the last couple of weeks I spent a lot of time with customer Web Federated Login workshops and implementations.
Not sure what happened but suddenly everyone is interested in SAML. It looks like more and more customers are looking into that because they have already implemented SSO for other applications like O365.

In one case a customer had an existing F5 configuration. In one other case we had a customer with Windows 2012 R2 and ADFS 3.0.

Both configurations are not officially supported yet but we got it to work! Specially the F5 configuration was tricky. But in general both are just another SAML 2.0 implementation.
We officially asked if those two configurations can be officially supported. It looks like it is more testing and documentation effort than any code change that is needed.
But it is not yet an officially supported configuration. Implementing ADFS 3.0 is quite similar than ADFS 2.0.

Win2012 R2 ADFS 3.0

ADFS 3.0 in fact is a nicer implementation and does not need any IIS components. Also the SSO portal application is now implemented in a way that the UI can be completely customized. You can add you logo, change the CSS or could even build your complete own page.

Also the installation is easier. ADFS 3.0 comes with Win2012 R2 and just needs to be enabled as a separate role. In contrast earlier versions shipped with SAML 1.1 support and you and to separately download and install SAML 2.0.

The configuration is very similar but you cannot use the cookbooks 1:1. Some configuration details are now set via PowerShell commands.
For example if you need to disable the extended protection when working with Chrome.

Domino SAML Implementation

In two customer situations we ran into an odd issue. When initiating the SAML login from the SSO portal like ADFS (with ADFS 3.0 the portal looks prettier and more customers might directly use the portal) redirecting to the Domino HTTP server caused a strange behavior.
The URL invoked should have been the default server URL but there have been som random chars at the end of the URL. Tracing turned out that this was a day one issue with Domino Web Federated Login (WFL) and it was never thought of that the first request is the login request with a redirect from the Identity provider (IdP) in our case ADFS 3.0 or the F5 applicance.

Even Domino uses a IdP Initiated model the first request was always initiated by Domino.

Here is the flow that Domino uses.

- Browser hits the Domino Server for a resource that needs authentication

- User ist redirected to the IdP for authentication --> the URL contains ?loginToRp to tell the ADFS server where to return to after authentication. This is a ADFS specific parameter which is for example not understood by F5.
  Example: https://nsh-win-ad.ad.nashcom.loc/adfs/ls/IdpInitiatedSignOn.aspx?loginToRp=https://domino.nashcom.loc/names.nsf
  At the same time the server sets an undocumented cookie "DOMRELAYSTATE" which contains some data in binary format (base64 encoded) which contains the location to redirect to after login.

- User is authenticated at the IdP. Either via AD name and password or with a Kerberos ticket (Integrated Windows Authentication -- IWA) if configured and the user and workstation are in the current AD.


- Browser redirects back to Domino with the SAML post request
 Example:
https://domino.nashcom.loc/names.nsf?SAMLLogin

- After verifying the SAML data, the user is authenticated and a LTPA cookie is generated


- At the same time the server reads the "DOMRELAYSTATE" cookie, removes it and redirects the user to his original location


Redirection Issue

In our problem case the user had no "DOMRELAYSTATE" cookie which caused the server to add some garbage to the URL.
We got a hotfix for the issue which will hopefully make it into one of the next IFs. The SPR for this defect is SPR # MKINA8XN74.

Summary

So in general if you want to implement SAML right now I would use ADFS 3.0 and Windows 2012 R2 if you have the choice - even it is not yet supported by Domino.
But ADFS 3.0 is the much better product which is better supported by Microsoft. And it is a much cleaner implementation. No dependency on IIS as well!




Server Controller Issue when applying 9.0.1 FP5 IF2

Daniel Nashed  31 March 2016 14:27:11
After applying 9.0.1 FP5 IF2 you cannot connect to the server controller -- again!
That's another issue that cannot be fixed allowing MD5 in the java security files.

What you need is an updated version of the JVM patch. The new patch has a release data of 25.3.2016 an can be downloaded from Fixcentral.

Here is the relevant information from the updated technote referenced in the SPR.

SPR RSSNA6UU79 is fixed in version 9.0.1FP5 Interim Fix 2 (IF2) via a server code fix and an updated JVM patch (SR16FP20). IMPORTANT NOTE: It is required to install both 9.0.1FP5IF2 and the new JVM patch to address the issue. Download links are available in the following technote: http://www.ibm.com/support/docview.wss?uid=swg21657963

If you already installed the JVM patch before you will run into an error:

Patching tree diff from ".\jvm" to ".\jvm_dst" using diff file ".\patch.diff"...
    You are attempting to patch:
      pwi3260sr16fp2ifix-20141203_01(SR16 FP2+IV66900))
    With a patch that is valid for:
      src1 pwi3260sr16fp15-20151106_01(SR16 FP15))
    Tree diff file patch failed.


My work-around was to re-install FP5 which includes the previous JVM patch.

From there I was able to run the new JVM patch installer and also upgrade to 9.0.1 FP5 IF2.

If that does not work in your case you have to go all the way back to 9.0.1 because that is the last release that contains a full JVM (9.0.1 -> FP5 -> New JVM Patch -> 9.0.1 FP5 IF2).

In my case reapplying FP5 was sufficient.

After the installation the java.security again has MD5 disabled and the console works. So apparently they build in a fix into IF2 and also did changes in the JVM patch.

There is also a fix included in the Notes Client fix 9.0.1 FP5 IF3 and you also have to update your local JVM with the new patch available.
I have so far just tested if the local server console on the Domino server works again.

But since the SPR is also fixed on client side, I assume it works as well.

Security Issue - IBM Domino AES GCM weak nonce generation vulnerability

Daniel Nashed  29 March 2016 12:02:24
There is a new vulnerability affecting AES GCM ciphers which have been introduced in 9.01. FP3 (enabled by default).
For very large data sets, IBM Domino Web servers using TLS and AES GCM generate a weak nonce which could be potentially used for a man-in-the-middle-attack.


All Domino 9 versions supporting those ciphers are affected and there is  new IF (9.0.1 FP5 IF2) which addresses this issue.


The IBM Domino AES GCM weak nonce generation vulnerability is tracked as SPR #KLYHA6ZP4F.

If you cannot update your server you should change your cipher spec to exclude those ciphers.


The following cipher spec would only allow the CBC ciphers and leave out the 6 GCM ciphers currently supported.


notes.ini SSLCipherSpecÀ28006BC0140039C0270067C013003D0035003C002F000A


The better option would be to install IF2.


Also the new Interims Fix includes a couple of other fixes. Including a fix for the Domino Console introduced by disabling MD5 in the last JVM patch as posted before.
There is no detail how SPR #RSSNA6UU79 addressed the console issue. I had no time to test it in detail yet.

Update 31.3.2016: There is a new issue with the Server Controller if you have applied the JVM fix as well.
The solution is to re-install the latest JVM patch which has apparently a fix as well.

CVEID: CVE-2016-0270 / DESCRIPTION: IBM Domino contains an unspecified vulnerability that could lead to session snooping using man-in-the-middle techniques.

Critical: glibc security and bug fix update

Daniel Nashed  17 February 2016 14:02:45

There is a critical issue with the glibc lib that Linux and other systems are using.

The best short description I found is the following:

"A stack-based buffer overflow was found in the way the libresolv library
performed dual A/AAAA DNS queries. A remote attacker could create a
specially crafted DNS response which could cause libresolv to crash or,
potentially, execute code with the permissions of the user running the
library. Note: this issue is only exposed when libresolv is called from the
nss_dns NSS service module. (CVE-2015-7547)"

Redhat already released patches:

https://rhn.redhat.com/errata/RHSA-2016-0175.html
https://sourceware.org/bugzilla/show_bug.cgi?id=18665

And there is also a patch from SuSE

https://www.suse.com/support/update/announcement/2016/suse-su-20160470-1.html

I have already updated my CentOS 6 Linux machines (via yum update).

Another interesting link is from Heise with some details in German:

Domino Server Controller does not connect after upgrade to Java6SR16FP20

Daniel Nashed  16 February 2016 18:33:18
The IBM Java Team disabled MD5 in there latest patch to tighten security. But the Server Console currently can only use MD5 right now.
So by this intentionally change by the IBM Java Team the Domino Console cannot connect any more.


For now to have the Server Controller local and remotely working again you have to re-enable MD5.

This is a similar issue than what we had when the IBM Java team disabled SSLV3 some time ago.


There are two lines that you have to change in the ..jvm/lib/security/java.security file.


You have to remove MD5 from the disabled algorithms for now:


jdk.certpath.disabledAlgorithms=MD2,
MD5, RSA keySize < 1024
jdk.tls.disabledAlgorithms=SSLv3, RC4,
MD5withRSA, DH keySize < 768


There is currently no other work-around for Windows. On Linux you could use the "monitor" command when using my start script and disable the server controller.

Domino Start Script New Version 3.1.0

Daniel Nashed  11 February 2016 15:26:10

As already mentioned at IBM ConnectED last week, I am working on a new version of my start script.

Most of the new functionality has been build in because I found it useful for the customer environments I am working in.

On top of the new functionality I added a new script "rc_all" that can start, stop, cleanup, diag ... all partitions a the same time.
The new rc_all script is a separate script that will search for your Domino partition rc-scripts and is mainly interesting when you run Linux machines with multiple partitions.

The new version of the start script has a couple of other additions which could be quite helpful.

You can edit the notes.ini with a simple"ini" command or show current notes.ini setting.
"lastlog" shows you the last log lines from the output log which could be input for a grep command.
By default the last 100 lines but you can specify an optional the number of lines.

The new version can also enable/disable/check the rc-service with the "service" command.

For diagnostics I added the "stacks" command which will quickly just dumps the call-stacks without other NSD functionality (less overhead).


The biggest change is the cleanup of the log files. You can now specify how long logs are stored and the logs are removed when you use the "clearlog" command
or when you enable the log clear functionality at startup in the configuration.

There are a couple of options and I also added some functionality for clearing temporary files at startup.

I have also added more functionality for the system database compact (you can leverage DBMT and there are separate other options) and also a separate log.nsf compact is available.

One of my customers also requested that the log.nsf can be renamed on startup.
I have added a new feature to move the log.nsf with a different name to a backup directory on startup after n days (this avoids creating a new database on every short term startup).

All functionality is completely customizable. There are settings for each of the commands.

I would be very interested to get your feedback about the new commands and options and before I release it, I would like to send it to some admins for beta testing.

If you are interested, feel free to drop me a short mail and I will send you the current state of the start script.
I am using it in customer environments and on my servers already in production.

But I still want to get some feedback before I release it. Documentation is already updated.

Here is the complete extract of what is new in this release.

I hope you like the new functionality

Daniel

New command "stacks" runs NSD stacks only

New option for command "archivelog"

- additional parameter to specify an additional string to add to the archive log file name


New Parameters to enable new features

DOMINO_LOG_CLEAR_DAYS
Number of days until logs are cleared

DOMINO_LOG_BACKUP_CLEAR_DAYS
Number of days until backup logs are cleared

DOMINO_CUSTOM_LOG_CLEAR_SCRIPT
Custom log clear script will be used instead of the standard log clear operations and replaces all other clear operations!


DOMINO_COMPACT_TASK
Compact task can now be specified. By default "compact" is used.

Option for the new "ini" command for changing the editor.


REMOVE_COMMAND_TEMP
-------------------
New option to specidy a different command for removing old tempfiles on startup (default: "rm -f")


REMOVE_COMMAND_CLEANUP

New option to specify a different command for removing expired log files (default: "rm -f")


Changes
-------

DOMINO_REMOVE_TEMPFILES
The script only deletes *TMP files in data directory which are at least 1 day old to ensure no important files are deleted.


The "nsd" command by default will generate a NSD with memcheck -- full nsd
"fullnsd" command is removed from documentation but can still be used.
"nsdnomem" is now used to generate a NSD without memcheck.


Problems Solved
---------------
When checking resources (shared mem, MQs, Semaphores) the ipcs command in combination with grep is used to check the resources for a certain partition/user.
The ipcs command does not allow to specify a user-name. The was a potential issue whe the login user-names where sub-strngs of each other.
Exampple "notes" and "notes1".  Even this is fixed it is still recommended to ensure that login names are not sub-strings of reach other.

Domino 9.0.1 FP5 IF1 with Security Fixes

Daniel Nashed  30 January 2016 14:47:59
There is a new IF1 for Domino 9.0.1 that includes two fixes we have waited for in the TLS area specially when communicating with STARTTLS and web-services as posted before on my blog.
       

SPR #KLYHA57S37 - Disable TLS Session Resumption on outbound connections by default        

This fix addresses and issue for outgoing STARTLS sessions on SMTP.

See some more details in my other blog post -->  http://blog.nashcom.de/nashcomblog.nsf/dx/tls-1.2-connection-issues-with-protection.outlook.com.htm

SPR #MKENA4SQ7R - Domino TLS 1.2 Client Hello does not offer a Signature Algorithm extension causing some handshakes to fail        

The second issue is a problem with a missing security algorithm extension that causes connection issues which happened in many customer environments -- and it looks like this happened depending on the certificate used in some cases.
And also what the remote server supported. The fix implements the missing extensions and improves compatibility.


SPR #KLYHA5YRVP - Recommended security fix for IBM Domino (technote 1974958)        

The Domino SLOTH vulnerability is about collision attack with the MD5 hash function that is used in the TLS handshake.
The fix addresses this issue.

Here are the main details from the TN describing the SPR.

CVEID: CVE-2015-7575
DESCRIPTION: The TLS protocol could allow weaker than expected security caused by a collision attack when using the MD5 hash function for signing a ServerKeyExchange message during a TLS handshake. An attacker could exploit this vulnerability using man-in-the-middle techniques to impersonate a TLS server and obtain credentials.

See more details here -> http://www.ibm.com/support/docview.wss?uid=swg21974958



SPR #DKENA32JMP - Add support for Extended Master Secret (RFC 7627) to TLS 1.2        

This is a quite new RFC which has been implemented by Microsoft and Google for their browsers recently. Both sides need to support this extension!
Domino does now support this extension which eliminates a risk of a man-in- the-middle attack in some situations described in the RFC below.


The Transport Layer Security (TLS) master secret is not
cryptographically bound to important session parameters such as the
server certificate.  Consequently, it is possible for an active
attacker to set up two sessions, one with a client and another with a
server, such that the master secrets on the two sessions are the
same.  Thereafter, any mechanism that relies on the master secret for
authentication, including session resumption, becomes vulnerable to a
man-in-the-middle attack, where the attacker can simply forward
messages back and forth between the client and server.  This
specification defines a TLS extension that contextually binds the
master secret to a log of the full handshake that computes it, thus
preventing such attacks.
