Hi @d1egoaz -- this is required when using some versions of Active Directory. It appears to be the problem blocking my issue #1519 as well.

Sorry, I totally forgot this PR,

I've already updated with the requested changes. I think it is ready for another review and/or merge.

I'm getting the following error:

KRBMessage_Handling_Error: KDC did not respond appropriately to FAST negotiation

Googling and following Github issue trails leads me to believe it may be fixed by this pull request.
