Fedora directory users - Oct 2006 - Cannot Setup PDC use Samba with FDS!

Hi everybody,

I''ve got a problems when I setup PDC use Samba3 with FDS.
I''ve followed HOWTO:Samba in Documentation Section. But when I map
ntgroup to
unix group, It''s state like : 
"[root@~]# net groupmap add ntgroup="Domain Admins"
unixgroup=DomainAdmins
rid=512
adding entry for group Domain Admins failed!"

I''ve tried to look around, and found some info. I will post here:
1. Kernel message:
"audit(1160332356.611:65): avc:  denied  { bind } for  pid=5752

scontext=root:system_r:samba_net_t:s0-s0:c0.c255

2. Error when I''ve try to use webmin to add NTgroups

"Failed to save group : /usr/bin/net failed :

[2006/10/09 02:44:37, 0] utils/net.c:net_maxrid(789)
  can''t get current maximum rid
"

Thanks,
