Source: Novell Certificate Server
Explanation: A User Certificate with the specified nickname does not exist.
Possible Cause: The certificate has been created, but eDirectory or NDS has not yet synchronized.
Action: The partition that the User object resides in must be synchronized to all servers that hold a replica before a newly created certificate can viewed. Normally, synchronization will occur automatically, but it may take some time. If synchronization does not occur within a reasonable timeframe, run dsrepair.nlm on the servers in the replica ring.
Possible Cause: The certificate with the specified nickname has been deleted or was not created.
Action: Create a certificate for the user with the specified nickname.
