Oracle databse NTS authentication

edited Jun 19, 2018 2:56PM in Database Administration (MOSC) 27 commentsAnswered

HI All

We have Oracle database express edition installed on Windows 7 machines. I want to connect to database using NTS i.e by changing sqlnet.ora file to use NTS authentication

SQLNET.AUTHENTICATION_SERVICES=(NTS)

Once this is done I want to connect usig:

sqlplus / as sysdba

This is not working . I am getting following error :

ORA-12638: Credential retrieval failed

My user id is present in ORA_DBA group.

Please let me know if this works on windows 7 or not. Kindly help me in fixing the issue.

Howdy, Stranger!
