Something I've been fighting since yesterday... I got trac installed, and working. Then I had to add security. Got all the moving pieces in - mod_ssl, auth_kerb. If I go to https://hostname/trac, everything's fine, a popup window asks for username and password. But if I go to https://hostname.f.q.d.n/trac, it fails, returning a 500? 501? Internal server error. I'm on a workstation running CentOS 6.5; my user, on Windows and running IE, gets the same. But if I open another firefox window with -P --no-remote, and pick another profile, it works. I certainly have no idea what to try in IE.... But I think there's some other misconfiguration of apache. Anyone have any thoughts on the matter? I don't think management will appreciate a head-shaped hole in the wall by my cube.... mark
