undefined method split for nil - ad_objects/group.rb line 51

[guttermonkey]

I've been using AdAuth in a couple apps for awhile and recently upgraded one to 2.0.3 and most of my users are fine, but for one particular user I'm getting an error in the above mentioned line about not being able to split nil. The relevant part of the stack trace:

adauth (2.0.3) lib/adauth/ad_objects/group.rb:51:in cn_groups' adauth (2.0.3) lib/adauth/ad_object.rb:111:inblock in cn_groups_nested'
adauth (2.0.3) lib/adauth/ad_object.rb:109:in each' adauth (2.0.3) lib/adauth/ad_object.rb:109:incn_groups_nested'
adauth (2.0.3) lib/adauth/authenticate.rb:26:in allowed_to_login' adauth (2.0.3) lib/adauth/authenticate.rb:10:inauthenticate'
app/controllers/sessions_controller.rb:8:in `create'

I've checked and the user is pretty much in the same groups as another user with similar groups. I assume that there's something misconfigured in her AD account, I just can't seem to figure out what.

Well I got the user working by removing one group from her group list. I'm not entirely sure I understand what that would change though if you have some insight.

I am having this same problem. I've managed to track it down to a group that has more than 1,500 members. When I look at ado.inspect, I see

:member=>[], :"member;range=0-1499"=>[ ... 1500 members listed ... ]

I'm guessing this is the issue as :member is actually empty causing the split to fail. Any thoughts on the best way to implement a fix for this?
