Netgroup/allow hosts problem

[Andy_Barsby at tectonic.co.uk]

Hi,

I'm trying to limit access to pre-defined set of hosts. I already have a
netgroup (in
NIS) defined, which I would like to use.

Now the man pages for samba say that I can do :

hosts allow = @netgroup

When I try this I am asked for a username/password even though the share
has:

public=yes

If I limit the hosts to specific hosts i.e.:

hosts allow = hostname1, hostname2

This works fine (i.e. no password required - access from only the specified
 hosts), is
there a problem with using netgroups?

Thanks

Andy
