Given a User ID, this method will:
A) Bind to the directory using the configured binddn and bindpw
B) Perform a search for the User Object in the directory, using
user_basedn, user_filter, and user_scope.
- C) Assuming we found the object, we will walk it's attributes
+ C) Assuming we found the object, we will walk its attributes
using L<Net::LDAP::Entry>'s get_value method. We store the
results in a hashref. If we do not find the object, then
undef is returned.
