Hi all.
I have, probably trivial, issue.
11.2.0.4 with October 2017 PSU. Linux 6 , kerberos 5
I am trying to setup up mixed authentication (different database users will use different authentication mechanism)
i.e. partially users will use kerberos authentication and partially password base.
1. When use SQLNET.AUTHENTICATION_SERVICES= (BEQ, TCP, KERBEROS5) (both client and server side)
And client not obtain kerberos tickets ---> can't use password authentication. error: ORA-12638
Once kinit running the connection is successful.
I've set SQLNET.FALLBACK_AUTHENTICATION = TRUE, as per note (972896.1)
As well SQLNET.AUTHENTICATION_SERVICES= (NONE,KERBEROS5,BEQ,TCP)
No success.
2. When use: SQLNET.AUTHENTICATION_SERVICES= (NONE) (client side)
I, obviously, can't use kerberos authentication but success to connect using password.
Please correct me if I am wrong but I think there is should be no issue to have such kind of mixed authentication, some clients use kerberos some others use password based. Whoever use kerberos run kinit to obtain tickets, whoever use password don't.
Thanks
Evgeni
