Can not connect to Oracle Database Server authenticated by Kerberos
I have configured my Oracle database with Kerberos authentication following this documentation link
However when it comes to the last step to verify the connection in Step 7.2.4 I am getting this error:
ORA-12154: TNS:could not resolve the connect identifier specified
I have created a user in Active Directory, then import this external user to Oracle DB as it says in step 7.1.9. Then I logged into the workstation as that domain user created in AD before running sqlplus.
Appreciate if anyone has any feedback and have come across this issue.
