Update of /home/cvs/samba/source/nsswitch
In directory va:/tmp/cvs-serv9645/nsswitch

Modified Files:
	winbindd_wins.c wins.c 
Log Message:
This commit finally gives us multiple wins server groups. We now
accept an extended syntax for 'wins server' like this:

  wins server = group1:192.168.2.10 group2:192.168.3.99 group1:192.168.0.1

The tags before the IPs don't mean anything, they are just a way of 
grouping IPs together. If you use the old syntax (ie. no ':') then 
an implicit group name of '*' is used. In general I'd recommend people
use interface names for the group names, but it doesn't matter much.

When we register in nmbd we try to register all our IPs with each group 
of WINS servers. We keep trying until all of them are registered with
every group, falling back to the failover WINS servers for each group
as we go.

When we do a WINS lookup we try each of the WINS servers for each group. 
If a WINS server for a group gives a negative answer then we give up
on that group and move to the next group. If it times out then
we move to the next failover wins server in the group.

In either case, if a WINS server doesn't respond then we mark it dead 
for 10 minutes, to prevent lengthy waits for dead servers.
