[Samba] winbind on Solaris8 problem concerning Domain Users

[test01 at pu-hiroshima.ac.jp]

Hello.
I am in a trouble.
ActiveDirectory(joind Domain Users in secoundry group) user can not use terminal in X.
If use,X session is freeze.

But,ActiveDirectory(not joind Domain Users in secoundry group) user can use terminal in X.
X session is not freeze.

Why?
anyone,please tell me how to work well.
(That is,X session is not freeze evenif ActiveDirectory is joind Domain Users in secoundry group)

My environment
solaris8,
samba3.0.10(winbind) on solaris8,
ActiveDirectory user number is about 5,000.
All ActiveDirectory user is set Domain Users group.
But Domain Users group is all secoundry group.
