[Samba] Samba x Ldap Latency change groups

[Flávio]

I'm with a problem and need some help with this.

So i'm using 389ds + samba 3.6.9,

I have Ldap integrated with samba, it works. I get login successfully,
attributes permissions with ACL, created Shared FOlders, all right.

But when I insert a user in a Samba Group,it  takes between 20 ~ 30 minutes
to works.
I already restart service, restart server, but only is inserted after the
time.

What i have to do ?
