First of all I believe that you can login into forms using /@tnsname syntax. The you need to buy Oracle Advanced Security option (part of sqlnet) Next thing to do is to configure Oracle+Kerberos+AD. Oracle has some metalink notes and white papers how to achieve this. Try those: Metalink.oracle.com Note:331252.1 Configuring Oracle Advanced Security Option (ASO) with Microsoft Windows Server 2003 Active Directory Kerberos KDC Doc ID: Note:331252.1 --------------------------------------------------------------------------------- Please consider the environment before printing this e-mail "Tieland, RC (Ruben)" <r.tieland@rocmn.
