Integration with Endian Firewall 3.0.5

Hello everyone, today in my tests with Univention, tried to integrate it with the Endian Firewall to make use of authenticated proxy, however when trying to integrate it to Univention, the following error appeared:

Failed to join domain: failed to connect to AD: Strong(er) authentication required

Someone here forum know how can I solve this problem?

Personal apology for creating the topic unnecessarily … I made a mistake here on the forum itself and ended up finding the solution.

However a question, is it making this change, some client, whether Windows XP or later, or Linux will face problems to log in this database? And will any service like radius or another, will also face a problem? If you know and can help me give thanks a lot.
