User Groups

Hello,

I have basic authentication working in Satellite 6.3 and it allows our users to log in and only create an account. I'm trying to set up the whole Roles/User group item. When I try to create a user group. and plug in the Distinguished name I always get a "is not found in the authentication source". in the logs I get this one error:
2018-03-07 14:13:02 0c930bdb [app] [I] Parameters: {"utf8"=>"✓", "authenticity_token"=>"6n/q2OXeLRdO3HZQsYXR4GzobalII+8IOMw8l9ALpqKy4wU4oDLt1Xqw9Pf0is5lhQFWlrYHliyBwg8ETKLpNQ==", "usergroup"=>{"name"=>"admins", "usergroup_ids"=>[""], "user_ids"=>[""], "admin"=>"1", "role_ids"=>[""], "external_usergroups_attributes"=>{"0"=>{"_destroy"=>"false", "name"=>"CN=Linux,OU=Security Groups,DC=myworkdomain,DC=com", "auth_source_id"=>"3"}}}, "commit"=>"Submit"}

Any ideas? I've opened up w a ticket w/ Redhat and its just being slow. Redhat Satellite 6.3 (Successful upgrade from 6.2)

Any info is greatly appreciated.
Thank You
