Description Stefan Metzmacher 2017-11-14 15:15:01 UTC 
It seems this attribute is only evaluated for objects with objectClass=computer
and not for normal accounts.

The presence of a supported encryption type should also have some meaning if
a key for that type is not yet stored in the database.

But the KDC should notice support for new encryption types and use
that for session keys.

I like our current behaviour where we have a way to control what encryption types are available.  Otherwise we have no way to, per user, control the encryption types.
