Managing ldap changes in connections

How do you manage changing the LDAP system on IBM Connections, What if your organisation decides to change the users DN. Maybe you know how to manage Connections, but what about CCM, Cognos and Forms. Get tips and best practices from the field

3. Overview • Task: Migrate from 1 ldap to another
 • Difficulty: DN for users changes
 • Migrate as is à Issues
 • Solution

5. Migrate from 1 ldap to another
6. Difficulty: DN for users changes • Customer LDAP team decided to change the user DN from 
 
 
 
 To

7. Issue #1 • If using default as GUID and no special config • à Users deactivated à New users
8. Issue #2 • Cognos Administrative user is an LDAP user • Does not exist on new system • Even if you create identical user and have custom GUID, you will have to remove and re- add from application roles due to different realm

9. Issue #3 • IBM Forms field mapping for Displayname
 • Our old LDAP had another attribute name for the users displayname then the new one.
 • As IBM Forms does not use the Profiles DSX services, you need to change the IBM Forms config
10. Issue #4 • Users will lose all access to CCM files
 • With the default configuration (no custom guid) Filenet will generate new users (just like the TDI Sync for profiles).
11. Solution: General approach • Implement custom GUID GUID LoginName • We already had a custom GUID (best practice) for users • Add one for groups as well if you plan on using groups in connections !!! • Do this before you add CCM to your deployment
12. Solution: General approach • The Identifier for Users and Groups in Connections is the GUID
 • A GUID for an object does not change
13. Solution: General approach • If an object is deleted, and recreated in LDAP, that object is recreated with a NEW ID (GUID) • Need to choose something “other” than the default! (e.g. uid, employee ID etc). • Custom GUID must follow following guidelines: • Must be unique and static • Must not exceed 256 char, for better performance se fixed length • Must be one to one mapping with the object

14. Solution: General approach
15. Solution: General approach • Must exist in LDAP Schema and in WebSphere Virtual Member Manager (VMM) schema • If not, add the attribute to the wimxmlextension.xml to make it available to WebSphere • Connections must be told about these attributes • LotusConenctions-config.xml • Must be specified in map_dbrepos_from_source.properties • Must be available in each object class assigned to your user or group
16. Solution: General approach
17. Solution: General approach
18. Solution: General approach • On WebSphere
 level, 
 wimconfig.xml is
 the place to be

19. Solution: General approach
20. Solution: General approach • We used a non-standard VMM Attribute for groups à wimxmlextension.xml
21. Solution: General approach • Corresponding LotusConnections-config.xml • On Connections you can override using LotusConnections-config.xml • I prefer not to override, especially when also using IBM Forms, IBM Cognos and IBM Filenet
22. Solution: #Issue 1 • The TDI Solution directory provided offers a solution to migrate your users (even if no custom GUID)
 • You can configure a mapping field that the sync process can use to identify the user in the old and new LDAP
 • Source LDAP is stored in the Profiles DB
23. Solution: #Issue 1 • Before Migration • Change following parameter in profiles-tdi.properties • Sync_updates_hash_field • And make sure you enter a unique cross LDAP value
24. Solution: #Issue 1 • Change all other needed parameters in the config file (LDAP, base entry, credentials, …) • Make the necassary changes to map_dbrepos_from_source.properties • Run the sync_all.dns script
25. Solution: Issue #2 • You will need to backup
 all users in the Cognos
 Admin role
26. Solution: Issue #2 • Update admin user and password in 
 /apps/ibm/bin/CognosConfig/cognos- setup.properties
27. Solution: Issue #2 • Run the following command while Cognos is running • Add the new account as admin in WebSphere • Update the J2C alias • Re-add Metrics Admins and remove Everyone
28. Solution: Issue #2 • Remove and add users from WebSphere roles

29. Solution: Issue #3 • Check /apps/ibm/data/Forms/extensions/ Builder_config.properties and verify that this is reflecting your new LDAP à Restart
30. Solution: Issue #4 • Make sure you have custom GUID setup for Users and Groups à It is that simple
 • If you do not, your users will lose all access to libraries and documents
 • Don’t listen to IBM, they tell you you need a Filenet services team* for this migration
31. Solution: Issue #4 • Check Waltz debug log to see if FileNet picks up the Custom GUID • Download and copy log4j.xml to your server and place it in the Application server log folder • Add the following arguments to your JVM configuration
 -Dlog4j.configuration=/apps/ibm/data/WebSphere/profiles/ AppSrv01/logs/log4j.xml -DskipTLC=true
32. Solution: Issue #4 • Screenshot JVM arguments`…

33. Solution: Issue #4 • Restart Filenet and check waltz.sonata.trace.log • Custom User Id Attribute is set to UID • Custom Group Id Attribute is set to null. This will change after migration to new LDAP
34. Solution: Issue #4 • Check FileNet SID’s for some users before migration as reference • 2 ways to do this • Database: UT_CLBUSERIDENTITYMAPPING (FNOS) • Command line: generateSID.sh
35. Solution: Issue #4 • After migration, check again for the same users after uploading a document with that user. If configuration is good you should see the user only once…
36. Recap: Migration steps • Backup Cognos and CCM Security • Migrate Profiles using TDI • Migrate LDAP in WebSphere • Migrate Cognos • Migrate Forms • Migrate CCM • Clearscheduler on all db’s
