Definitely not for 3.2.2, I was considering v3-devel.

I created a new patch that have a lookup_domain_name() and lookup_name()
functions that differ only by the domain + name vs fullname variables
being passed in.

I did not change any logic, I just got the first part that splits the
string and make it an optional part. This way we do not see ugly things
like building a dom\name string just to see it split out back in dom and
name as the first thing inside lookup_name().
As a bonus, in this patch you get one less fstring too :-)
Btw in a couple of places it seem it would be useful to pass to
lookup_name() the separator to use, what about adding a 'separator'
parameter to it (can be NULL and defaults to '\\' in that case) ?
