[rt-users] My_LDAP AUTH FAILED error with ExternalAuth

I'm not very familiar with Linux or Perl and have mostly been following guides that I can find from Google in getting RT set up for my company. I'm running a Ubuntu 13.10 server with RT 4.2 and ExternalAuth (installed via CPAN) to connect to Active Directory. I've run into roadblocks nearly every step of the way but I feel like I'm almost there. I was able to log on with AD credentials at one point (taking me to an error page first but I was logged in when returning to the main page) but once I added the 'group' and 'group_attr' settings, it's now not letting me log in.

Apache's error log when attempting to log in:

[10263] [Thu Nov 14 20:01:23 2013] [info]: My_LDAP AUTH FAILED: tamas.mccoy (/opt/rt4/local/plugins/RT-Authen-ExternalAuth/lib/RT/Authen/ExternalAuth/LDAP.pm:289)
