Common Network Device Enrollment Service (NDES) configuration wizard failures

Thank you Rob for you very detailed answer!

In fact I disabled EPA because I found out that it does not work with it enabled and still using NTLM. So I disregarded that "easy way out" pretty fast.

As of now we try to get Kerberos working as it should. But we fail miserably.

Today I found out in a trace log with curl, that we have some kind of gss-api problem, that sounds like the realm is wrong or written with the wrong case. But it is not...

But I think that this problem is too special for you to help us out... I understand that and I thank you again for your time as of now!
