I just upgraded to the latest version from 3.x.x. I also converted to mySQL. Everything seems to be working fine, but I can't authenticate using reverse lookups like I used to be able to. This is the config line I used: ./configure --enable-roaming-users=y --enable-mysql=y --enable-ip-alias-domains=y --enable-default-domain=box5.net Yes, the reverse lookup records are right. I can authenticate anything off box5.net without the domain, but anything else needs either @domain.com or %domain.com added to the username. It works fine once the domain is appended. Any help would be GREATLY appreciated. I need to get this resolved ASAP. -Andy [EMAIL PROTECTED]
