Confirm that all of the connectors are installed. One connector must be installed for each directory source being synchronized.
Confirm that the source connector detects the change to the user. Use the central audit log to determine if the connector for the directory source where the user was added or modified detects the modification.
Verify that all connectors are in the SYNCING state using the Identity Synchronization for Windows console or idsync printstat command.
Determine if the destination connector processes the modification.
