[Samba] %M client DNS name resolution

[phillip.griffith at srs.gov]

Since upgrading from 2.2.8a to 3.0.11, I'm having trouble with the %M 
samba variable that represents the client's DNS name.  Instead of the 
hostname, it's resolving to the IP address.

I added "exec = /data1/smbvars.sh "%m" "%M" "%I" "%a" "%D" "%u" "%H" "%g" 
"%U" "%G" "%S" "%P" "%p" "%h" "%L" "%N" "%v" "%d" "%R" "%T" 
>/tmp/smbvars.txt" to the global section of smb.conf, and the results 
follow:

Client variables...
%m = p-griffith = Client's NetBIOS name
%M = 192.168.174.212 = Client's DNS name
%I = 192.168.174.212 = Client's IP address
%a = Win2K = Client's architecture

(IP addresses have been changed to protect the innocent.)

I'm running Solaris 9, and I have no trouble resolving IP addresses to 
hostnames, or hostnames to IP addresses, using getent(1M) from the command 
line.
