[Samba] can't open/create local group with usrmgr

[yaya]

Hi Samba users,
First I can't open/create local group with usrmgr.
Second creating global group and user is working, [third] but adding users 
to this [global] group failed..
I do this as yaya that has policy rights for everything, like "Domain 
Admins" has, and when I do it as root, it still doesn't work.

Here's some infos:
[root at sma-server-1 ~]# rpm -qa | grep samba
samba-3.0.20-2
system-config-samba-1.2.31-1
samba-common-3.0.20-2
samba-client-3.0.20-2
[root at sma-server-1 ~]# rpm -qa | grep openldap
openldap-2.2.23-5
openldap-devel-2.2.23-5
openldap-servers-2.2.23-5
openldap-clients-2.2.23-5
[root at sma-server-1 ~]# rpm -qa | grep smbldap-tools
smbldap-tools-0.9.1-1

The log:
[2005/10/24 16:32:27, 0] lib/smbldap.c:smbldap_open(822)
  smbldap_open: cannot access LDAP when not root..
[2005/10/24 16:32:27, 0] passdb/pdb_ldap.c:ldapsam_search_one_group(1972)
  ldapsam_search_one_group: Problem during the LDAP search: LDAP error:
(Time limit exceeded)
[root at sma-server-1 ~]#

When I do it as root, the usrmgr message:
The following error occured creating the local group Staffs:
Access is denied.

I installed Samba with ldap backend and applying IDEALX. I need to 
create/manage users and groups with usrmgr.

Thank you very much,
yaya
