Yes oh dear god yes !
This is such an absolute pain, and its absolutely pointless ... we don't 
*need* to know it's hex , because hex is the only bloody format that 
anyone writes hashes out in directories these days :\

It's annoying for anyone wanting to use the same hashes for samba 
Authentication as RADIUS authentication, because samba doesn't like the 
0x prefix, and so you have to write out the same hash in two different 
attributes.

So yes, if theres not a really good reason not to apply this patch, i'm 
all for it.

Thanks,
Arran
