I have 2 SP 2013 SP1 environments, testing and production. Both have user profile service application (using FIM agent) configure to get profiles from AD. Both the farms have similar service connection and filter settings but production is missing a few users who are present in test environment.
I have run full profile multiple times and checked the connection filters, user account is not disabled hence present in test farm. I checked the ULS of production and found the following for one of the missing user:
Returning AD resolve match 'i:0#.w|domainA\user' for input 'domainA\user'.
User profile record of "domainA\user" was changed by "domainB\farm_account".
We have one forest with multiple domains but all configuration in test and production are similar hence I'm confused as to why one farm imports the users when the identically configured other farm fails to import them.
Any suggestions/recommendation would be appreciated.
