VMMSYNC User Synchronization fails with null Error count = 1



User synchronization fails with [ERROR] The VMM user synchronization failed. null Error count = 1


Unable to bring users from the Virtual Member Manager into Maximo Asset Management

Diagnosing The Problem

To diagnose null errors with VMM sync it is best to setup trace logging on WebSphere using the following steps.

1) Log into the WebSphere Console - > Choose Logs and Trace
2) Click on your server name - > Choose Change Log Detail Levels

3) Enter the following into the description box.*=all:*=all:*=all:*=all

4) Apply and Save then Restart the Application Server.

You will now have a trace log writing to your servers logs folder, open the trace log and you may see the following error causing null to be returned by the repository to Maximo.

CWWIM4548E The LDAP attribute used as an external identifier 'ibm-entryuuid' has a null value for entity 'uid=maxadmin,ou=users,dc=ibm, dc=com'.

Resolving The Problem

To correct the above problem you will need to update the wimconfig to add the following external attribute if it does not exist <config:externalIdAttributes name="distinguishedName"/>.


1) Search for <config:attributeConfiguration>

2) Then after it add <config:externalIdAttributes name="distinguishedName"/>

3) Save the files, restart the server and attempt to synchronize the users again.
