[Samba] problem adding group to ACL

[Xiaping Lin]

Hi,
I recompiled the latest stable version Samba-2.2.8a with ACL support on 
Solaris 2.7 box.

But I can not added groups on the samba server (listed in /etc/group) to 
ACL using WinXP SP1 client machine. I get error "Unable to lookup user 
names for display". (Property->Security->add)

Adding more users to ACL works fine.

I noticed this problem was reported before

But, I can not find the reply/solution for it.

Would you please help?

Thanks

Xiaping
