My company has numerous applications that can connect to our 11g server via TNSNAMES without any trouble. However, a new app was introduced which utilizes Oracle SSO. For this app to connect, users must have SQLNET.AUTHENTICATION_SERVICES= (NTS) set in their SQLNET.ORA file. However, once the users set this, none of the other apps they run can connect to our database. They have to comment out the SQLNET.AUTHENTICATION_SERVICES= (NTS) line in order to connect with the other apps. Is there any way to get all of these apps, the one which uses a SSO connection and then the other regular connection apps, to work together? As is we have to change the SQLNET.AUTHENTICATION_SERVICES setting everytime we go back and forth.

Thank you.
