||IBM Connections – How to switch to a custom global unique ID for users
IBM Connections – How to switch to a custom global unique ID for users
many of our todays support cases is related to non-working profiles in IBM Connections.
If users change their name, switch from one to another location or simply get a new account their profile in IBM Connections might get inactivated because the hash key between LDAP and database has changed.
There are three possible hash keys:
- UID: Often a bad choice, as this might change
- eMail: Also a bad choice
- GUID: Unique ID – a good choise
So GUID is the attribute you should go for if you have non-unique eMail or UID values in LDAP.
GUID is a canonical String that is generated from:
- AD: objectGUID / objectSID
- Domino: dominoUNID
But in daily use the GUID value is not really as shiny as it seems… Due to the fact that many Domino administrators copy documents (STRG-C + STRG-V) duplicate dominoUNIDs can occur – which might kill an IBM Connections profile. I heard from customers with Active Directories who delete an AD account and recreate it if a person changes names… The IBM Connections profile gets inactivated.
But some customers implemented another unique key (such as employee number) into their LDAP in order to avoid such problems. The question comes up, how do I need to configure IBM Connections to make use of this new unique ID?
Everything is documented in detail and works very well (Please note that you should be very careful using this approach if you have CCM libraries in use – this change might break the access rights for all users!!!):
1. Depending on what attribute shall be used you need to first define a wim extension:
1.1 Attributes that are not part of PersonAccount schema – go to ../DMGR/config/cells/CELLNAME/wim/model and create a file “wimxmlextension.xml”
<?xml version="1.0" encoding="UTF-8"?>
1.2 If your customer uses a LDAP attribute that is already part of the PersonAccount schema you can directly go to 2)
2) Open the wimconfig.xml (here we add customerUserID as an supported attribute):
<config:attributes name="userPassword" propertyName="password"/>
<config:attributes name="customUserID" propertyName="customUserID"/>
3) open and edit the LotusConnectionsconfig.xml file and add the following part:
<sloc:serviceReference profiles_directory_service_extension_enabled="true" serviceName="directory" custom_user_id_attribute="customUserID"/>
4) Make a full resync of all nodes
5) TDI: edit the file “map_dbrepos_from_source.properties” and map the new customerUserId to GUID:
6) TDI: open the file “profiles_tdi.properties” and change the field “sync_updates_hash_field” from:
sync_updates_hash_field=uid (or mail)
7) start sync_all_dns.sh and check if the profiles have been correctly updated:
db2 “select PROF_GUID from EMPINST.EMPLOYEE” should show the new customerUserID`s
8) Revert back the change in profiles_tdi.properties so that the sync_updates_hash_field is set back to the guid value
A profile with the canonical String from a dominoUNID:
A profile with the customUserID as identifier:

Update to RHEL 7.4 breaks DB2 Cluster (TSAMP / RSCT)
after updating a RHEL 7.3 system to RHEL 7.4 the DB2 HADR / TSAMP cluster stopped working. I was able to establish the HADR connection but the service IPs were not assigned to the network interface.
Executing the command “lssam” to display the cluster state showed that nearly all resources are in the “Pending online state”.
First of all I though it is an issue with the cluster config – so that I deleted th

IBM Connections 6 – Following and Followers blank
during the last weeks we had to deal with a strange problem in an IBM Connections 6 environment.
The system was migrated from IC 5.5 to IC 6 and live for about 4 weeks when suddenly the following problem occurred:
Neither users that I follow nor followers were shown in the UI. Despite installing the latest Fixes no bigger changes have been performed on the system.
I was able to follow a user:

Exchange integration into WebSphere Portal (SSO – Kerberos)
During the last years working with Portal I had several challenges with WebSphere Portals HTTP Outbound Proxy (aka. Ajax Proxy) in terms of authenticating backend calls to various other systems.
What we`ve done so far in terms of SSO / backend authentication:
– Authenticating using LTPAToken
– Authenticating using SAML
– Authenticating using SPNEGO / Kerberos (this was a new one for me)
The challenge this 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
SAML & IBM Connections 5.5 – not a dream team|
Fri, Aug 18th 2017 7:45a GIS Techblog
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

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

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.
