OK - I changed my TNS_ADMIN to point to a local copy of SQLNET.ora and set the authentication_services= none and as expected I can now log in. This isn't a great solution since I don't want to make people run off a local copy of the sqlnet.ora -- I'd rather play by the corporate rules. Is there a way to make the NTS authentication work through a VPN connection? Received on Tue Feb 12 2008 - 12:37:54 CST
