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 http://marc.theaimsgroup.com/?l=samba&m=102127292621531&w=2 But, I can not find the reply/solution for it. Would you please help? Thanks Xiaping
