Hi All,

I am using Oracle 9i as a backend for ASP.net web application. And i want to have windows authentication for the application for that i have set sqlnet.authentication_services to NTS in the sqlnet.ora file on the oracle server. The .Net code is on machine A and Oracle DB is on machine B.

When browser settings on A for logon for intranet are set as "automatic logon only in intranet zone", the application works fine. But when i change the settings to "Prompt for user name and password", supply my NT user name and password it gives me following error: ORA-12638: Credential retrieval failed

I want to know the role of NT logon credentials in initializing the Authentication adapter. How and when does it get initialized? Also whats the solution for this problem.
