During an AD Synchronization, you may also have AD provisioning jobs running. This may result in some Identities to have 2 AD Accounts with identical object GUIDs mapped.
This is a rare occurrence caused by AD provisioning jobs, while simmultaneously running AD Synchronization.
The list of accounts in IM is created at a point in time when the account is not yet created in AD. The list of accounts in AD is then created when the account has already been created.
Set MaxInstance to “-1”at the JobTask “FullSync”. This ensures that no other ADS-Job can run during a FullSync.
