3055 Logons are only enabled for user DBC.
Explanation:
Logons must be enabled only the DBC. Thus, at the moment, logons are disabled to any user except DBC, because (a) a DBCENABLE LOGON command has been executed, or (b) a logon has been attempted before the Teradata system has been fully initialized (that is, before the table initializer has finished running).

For Whom:
End User.
Remedy:
Use the console command ENABLE LOGON to enable logons to any user in the Teradata system, and make sure the Teradata is properly initialized.
