SAP EP - Group and user consistent error

Hi all.

We have a SAP EP.

We define UME datasource as LDAP .

We create some Groups in UME. for example 'SSOR3'

For example, group 'SSOR3' have 5 users.

If one of these 5 users is deleted in LDAP, and this user will not exist in EP UME.

Then if we go to EP-useradmin task, search out this SSOR3 group. And if we want to search other users in this SSOR3 group, we meet with one exception, and UI prompts me one error occurs, ask me to check log.

I check the log, and found that EP try to search for the deleted user and throws out exception.

I think this error is because when one user is deleted from LDAP ( not in UME ), the Group-User relation is still existed and throws error.

Is there some tools to check the consistent and relationship ?
