ORA-20001: Unauthorized for Login!

edited Jan 27, 2011 6:59PM in Database Administration (MOSC) 6 commentsAnswered
Some of our windows domain users use the Oracle user 'SCOTT' to connect to our Oracle instance  from windows client and get the follwoing error message: Skipped error 604 during the execution of SYS.LOGON_CHECK
ksedmp: internal or fatal error
ORA-00604: error occurred at recursive SQL level 1
ORA-20001: Unauthorized for Login!
ORA-06512: at line 4
But  other windows domain users use the same Oracle user 'SCOTT' to connect to the same Oracle instance  from the same windows client  and it is Ok.
If I grant DBA role to Oracle user 'SCOTT', all windows domain users can login successfully.What could be the reason ?

Howdy, Stranger!
