12640, 00000, "Authentication adapter initialization failed"
// *Cause: The function specified in the authentication table entry for the // service failed. // *Action: Enable tracing to determine the exact error.
My guess is one of these services is not (correctly) installed. And I must say, I have never seen such a mess - do you not have a corporate guideline that specifies *which* protocol is used?
NTS: Ultimately based on Kerberos, so why both?
Where does TCPS come in? Do you encrypt your SQL*Net based
Kerberos is Advanced Security, NTS is basic.
Using an account with password requires Advanced Security
to be bypassed (switched off). Setting
SQLNET.AUTHENTICATION_SERVICES=NONE does just that. Do you want to log on with user/password? Your configuration does not tell that - it tells a different story; one of external authentication. In order to allow for that, you must log on, and so must your third party app.
