BDC event error 5731

My BDC has the event5731 in event viewer. I have tried the fix from Q172302 with no luck. The event log fills up with these message every five minutes:
replication of SAM local group “RID: 0xa91” failed group does not exist

replication of SAM local group “local” failed
user already exists

Does anyone have any insight that might help me?
thanks for your time
