How to determine which users or groups in the wcm db are missing from the ldap when running memberFixer
To create a non-existant user in the WCM/JCR database, I used the Support Tools Portlet to edit the Authors field for a presentation template:
Enter this tracestring under Administration > Enable Tracing:
Run memberfixer against the library containing the Presentation Template with the invalid user.
Search or grep trace.log for "could not be found" to identify all missing users and groups. Here is the entry in trace.log that corresponds to the "bogus" user:
[9/2/14 10:12:25:343 EDT] 000000ca PrincipalInfo 2 Neither a user or a group with the ID 'bogus' could not be found
