In AuthToken the attributes are actually stored in a Hashtable<String, Object>, and there's already a generic get() that returns Object, so we probably can just add a set(String name, Object value). If the list of groups is only kept in memory I don't see a reason to concatenate them into a single string.

3. The listGroups() is always called with "*" filter so it will pull all groups in the database, then the code will execute a search operation for each group to check if the user is a member. I think this is highly inefficient. The listGroups() should have been called with the right filter to get the right list of groups with a single search operation.

4. When constructing a DN the attribute values should be escaped with LDAPUtil.escapeRDNValue() to prevent problems with DN special characters. 5. When constructing LDAP filter the attribute values should be escaped with LDAPUtil.escapeFilter() to prevent problems with LDAP filter special characters. 6. If there's an exception the method should rethrow the exception so the client will see the problem. 7. The array of groups can be added into a list with a single operation: groups.addAll(Arrays.asList(groupsArray)); 8. The Utils.stripQuotes() right now is called multiple times for the same value. It can be simplified as follows: matched = groups.contains(Utils.stripQuotes(value));
