I cannot remember having a previous hex-based case-sensitivity issue in 
Samba4.  Please correct me if I am incorrect.

If W2K8 is matching against a lowercased hex string, and we have not 
previously encountered any case-sensitivity issues, can we not assume 
our initial implementation implied the wrong case for hex strings?

After my testing with and without Tridge's casing patch, doesn't it make 
more sense to address any new case-sensitivity issues as they occur, as 
opposed to implementing new, special-cased functions every time we 
discover a case discrepancy?
