DBC.logonoff : Event column

Account Name Column

The AccountName column is the current unexpanded account name for the session.

Possible Values For Event Column

•  Logon
•  Logoff
•  Logon failed

This value means a (Authentication Failure ) logon failed for reasons other than “Bad User,” “Bad Account,” or “Bad Password.” Currently, those other reasons are a failure to conform to Logon Rules or an attempt to log on without a password, where the TDP logon exit does not approve the logon.

The external profile associated with the logon request does not exist. External profiles are stored in the directory server.
•  Forced off

This value indicates that the user session was terminated from the Teradata Database console or the PM/API.
•  IP restriction

This value indicates the user is not permitted to log on from the IP address used.
•  Authentication failed
•  Bad authentication

This value may indicate other authentication errors: bad authentication field, deprecated logons, decryption failure, and so forth.
