I just created an account on 2 different databases on linux using "OPS$<myusername>". No domain name. One server knows how to authenticate via AD, the other does not. Both allowed an OS authenticated login from a Windows client. Setting remote_os_authent=true is a rather dangerous option. If is *extremely* easy for a windows client to gain ownership of the database when remote_os_authent=true. If you set it, you better be using invited_nodes in sqlnet.ora to limit who can get to the database. Jared -- Jared Still Certifiable Oracle DBA and Part Time Perl Evangelist
