Hi,

Enable SQL*Net tracing:

12638, 00000, "Credential retrieval failed"
// *Cause:  The authentication service failed to retrieve the credentials of a
//          user.
// *Action: Enable tracing to determine the exact error.

Best regards.

Frank

Credential Retrieval failed ORA-12638 occured while trying to connect remote database through publlic database link.
We are able to connect the remote database through tnsname that is created for the same dblink but through dblink above error is shown.
If the AUTHENTICATION_SERVICES = (NONE) IS SET THEN THE CONNECTION IS OK. WHAT WOULD BE THE PROBLEM IF THE PARAMETER FOR THE AUTHENTICATION_SERVICES = (NONE) IS SET.
PLESE SUGGEST AS SOON AS POSSIBLE
