[rt-users] Undefined subroutine&RT::Authen::ExternalAuth::UserExists - Probably Resolved

Tue Nov 18 13:09:20 EST 2008

Ripped out everything, including perl, apache2, rt, and the equine
companions they ambulated towards me with.  Obliterated any file that
looked like it was even thinking of the string "authen".  Put it all
back very slowly.

While i've made some mistakes in my LDAP config and I'm not successfully
authenticating, I get a proper "Your username or password is incorrect"
on the login page, not the horrible perl error from before.

Not really sure what could've done it.  At some point when 06 was out, I
think I tried using the CPAN version of that: I thought I blew all those
files away, but at this point I'm betting I missed one.

I hope this info is useful to someone at some point.  Now I go back to
trying to sweet-talk my AD server.
