Hi, Just to back up Job Miller's post, I was able to setup proxy authentication using Java/Tomcat/11gR2 with client auth. This allows the session using the proxy to be audited as well which is requirement in some environments. It essentially works as a poor man's SSO without the need of an LDAP where Tomcat does the authentication and the database does the authorization. -- mohammed On Fri, Jan 11, 2013 at 1:23 PM, TJ Kiernan <tkiernan@xxxxxxxxxxx> wrote: > Change the default > SQLNET.AUTHENTICATION_SERVICES= (NTS) > to > SQLNET.AUTHENTICATION_SERVICES= (NONE) > > in the client's sqlnet.ora.
