||SAML & IBM Connections 5.5 – not a dream team
last week we had to fight with an activation of SAML on a IC 5.5 CR3 environment.
The setup was:
- IBM Connections 5.5 CR3 as test instance
- ADFS Server 3.0 (I know… it is only tested with ADFS 2.0 – but works with 3.0 too)
We followed the instructions from the IBM Connections Knowledge Center. Smooth setup everything standard procedure. When testing this setup, the redirect to the IdP was initiated. After logging into the IdP the browser was redirected to IBM Connections ACS app. But then a loop started. IdP – Connections – IdP – Connections – IdP …Just until the ADFS Server detected this look and cancelled the request (from the ADFS error log):
Encountered error during federation passive request.
Microsoft.IdentityServer.Web.InvalidRequestException: MSIS7042: The same
client browser session has made '6' requests in the last '2' seconds.
Contact your administrator for details.
(SamlContext context, MSISSignInResponse response)
(ProtocolContext protocolContext, PassiveProtocolHandler protocolHandler)
Enabling traces on both InfraCluster & UtilsCluster showed us the following error message:
[8/15/17 9:06:59:669 CEST] 000000fb ContextManage 3 Opaque token lookup via mbean will not occur.
[8/15/17 9:06:59:669 CEST] 000000fb ContextManage 3 Exception getting opaque token from originating server.
com.ibm.websphere.security.auth.WSLoginFailedException: SSO token uniqueID not null, but opaque token not found. Need to re-challenge the user to login again.
There is a technote for this describing this issue.
Basically this technote summarizes that this problem is caused by:
“In Websphere Application Server 18.104.22.168 and 22.214.171.124 there are two settings which can contradict each other in certain circumstances if they are both set to true. ”
Addition to this: The properties IBM talks about is also active in WAS 126.96.36.199. From 188.8.131.52 on the property was removed.
The property is called “com.ibm.websphere.security.disableGetTokenFromMBean”
Use this property to disable the outbound SOAP call to retrieve the subject from the originating server when Single Sign-On is enabled. Typically, when Single Sign-On is enabled, and an inbound request needs to be authenticated, the receiving server attempts to retrieve the authentication from the originating server. The connection between the sending and receiving servers never times out during this callback process. When this property is set to true, the receiving server does not attempt to authenticate the inbound request.
And it is set to true by default. This caused the loop.
Setting this to “false” and restarting the cell, SAML authentication immediately started working.
It would be very helpful to get a short link in the IBM Connections 5.5 Knowledge Center to the above technote! This would have saved quite some time.

User provisioning for IBM Connections Cloud – You have the choice
Customers who use IBM Cloud for Connections, Sametime or other applications face the problem to manage their cloud accounts. For some single users you can use the Web frontend to add or change user accounts or to assign subscriptions and licenses to users. But in real world scenarios it is not possible to manage thousands of users manually or to keep them synchronized with an on-prem user repository or LDAP.
This can be handled

IBM Docs – Migration from DB2 –> ORACLE
within our last big project, we had the challenge to transfer the IBM Docs database from DB2 to ORACLE. Within this database comments and other document related data is stored.
Officially there is no script available to perform this move using DBT (remove constraints / transfer / reapply constraints). We looked into the database and figured out how to perform this task using DBT – so we are not dependent on any other products. We m

IBM Connections – trouble adding additional nodes
we are currently involved in a project where we installed a 1 node IBM Connections 6 Cluster and later added a second node to the cell.
So far so good… Everything that needs to be done after adding the second node is described here … Everything? Yes, mainly… but not in the mandatory details as I think! Missing custom properties and other settings might result in non-functional nodes. Especially not setting httpSess

SNOUG 2017 Presentation – SikaConnect goes External

Whiteboard in IBM Sametime Meeting 9.0.1 removed
IBM implemented in Sametime Meeting 9.0.1 a whiteboard function as technical preview. Ben described in his articel how to enable this feature:
With the current cumulative Fix 901-ST-General-FP-SMOL-AK4G43 for the Meeting Server IBM has removed this function.
The response on my PMR was:
“I can confirm The Meetings Whiteboard feature release is being put on hold indefinitely.

Wikis content not accessible…
it`s been quite a long time; many projects at the moment so that blogging needs to wait
Last week we had a very interesting problem at one customer’s environment. When accessing a Wiki, the page was displayed blank – no content was available. Browsing to older versions of this wikis worked.
The error in the log:
Parsing error… Wikis content (the body) gets store in the filesystem as xml files. If you access a Wiki there is a XML parser

Automatic WebSphere plugin modification II – PowerShell for Windows
some months ago I published a shell script to automatically modify the Primary / BackupServer definition in a WebSphere plugin-cfg.xml file.
As we have several Windows customers we decided to transfer this script to PowerShell so that it is also useable for a Windows Cluster installation. My colleague Jan Bruns did a great job implementing this script.
It basically works the same way as the Linux script:

IBM Connections Docs – file preview not possible for some CCM pdf files
last week we had trouble in a customer environment using the file preview functionality for some pdf files (only those that were uploaded using CCM).
Instead of a preview the message was displayed:
At the same time we saw the following warning in the log:
The mime-type was set to “image/pcl” instead of “application/pdf”… this mime-type is not supported by IBM Docs File viewer. We had to dig deep into th
