Authentication database contains an inconsistency

Authentication database contains an inconsistency

This message is displayed while running one of the programs associated with the TCB or a protected subsystem. The Authentication database integrity is in question. The Authentication database is a composite of the Protected Password database, the Terminal Control database, the File Control database, the Protected Subsystem database, and the System Defaults database, and the message applies to all of these. Either a data entry is not present when expected, or the items within an entry are not correct. This message is intentionally vague. The invoking user is alerted to the problem but not given enough information about the cause to allow them to exploit an integrity problem within the security perimeter. The real reason for the problem may be found in the audit trail if the Database Events event was enabled for the user that generated the message. Running authck(ADM) should help you determine the problem.
