lanman apis 47 and 53

I've implemented these two calls (NetUserEnum and NetGroupEnum) in
smbd/lanman.c (enclosed patch is against 2.2.2).  The NetGroupEnum is still
hard coded to return the basic non-administration groups but the
UserGroupEnum goes to the passdb enumeration to get the usernames.  Is there
work going on somewhere on unix-domain group mappings?  Also, if there are
too many user names to fit in the client buffer, it just ignores the
remaining names and sets the error flag to 234 (overflow error number from

I hope this is useful for others.  It seems to work here.

As Andre Tridgell is now working for Quantum, expect the support for
this to get a lot better soon.

I'll ask him about the missing lanman RAP calls.
