ES4 user account cannot be found under livecycle console

[Parky_Chow]

I found a pain point after AD synchronize with LiveCycle ES4, some of the accounts in LiveCycle are missing.

We found that those accounts mark [OBSOLETE] in table [EDCPRINCIPALENTITY] are failed to search in LiveCycle console.  Any work around can reactive this account in LiveCycle without re-creating a new AD or changing the username ?
