samba - Sep 2013 - "net idmap dump" and "wbinfo" shows different GIDs for same SID

Hi!

I'm apologize for my poor English, but have a question.
This question is a shorter than one i posted not so long ago 
(https://lists.samba.org/archive/samba/2013-September/175649.html) and 
received no answer for a while. In this question i took a log from the 
different server, but this is no matter: the problem persists on all of 
my servers.
So, my OS is FreeBSD 9.0, my Samba is 3.6.18 acts as a domain member.
Suppose i have a local group "samba_sge_public_createdir", created
with
"NET SAM CREATELOCALGROUP".
"getent" and "wbinfo" shows this group with GID 30002 and
SID
S-1-5-21-2085021927-1344845373-2015074135-1012.
But, "net idmap dump" shows this group with GID 30008 and shows no
group
with GID 30002 at all.

Such a problem arise from time to time and my users can't access to 
shares because samba thinks they don't a members of a certain group.
Help me, please. How can I solve the problem? I'm really troubled:(

My Samba global config:
[global]
         dos charset = CP866
         workgroup = HTS
         realm = HTS.KH.UA
         server string          security = ADS
         map to guest = Bad Password
         local master = No
         wins server = 192.168.32.5
         winbind enum users = Yes
         winbind enum groups = Yes
         winbind expand groups = 3
         winbind nss info = rfc2307
         winbind max domain connections = 50
         idmap config HTS : schema_mode = rfc2307
         idmap config HTS : range = 10000-29999
         idmap config HTS : backend = ad
         idmap config HTS : default = yes
         idmap config * : range = 30000-59999
         idmap config * : backend = tdb
