I can't get root level access rights(sudo) from ldap

[Zengming Zhang <nicegiving@gmail.com>]

Hi everyone:

	Please help me, I can't get root level access rights(sudo) from
ldap.When I try to use sudo command, there is an error report:
	"user is not in the sudoers file.  This incident will be reported."

	I am going to build a cluster systems, there is a file server and some
client computers. The operating system of file server is Redhat
Enterprise Linux v5.3, and the client's is Ubuntu 8.10 desktop edition.
        When users login on a client, the client will get user
authorization info from server and mount its HOME folder automatically. 

	I installed openldap server(openldap-2.3.43-3.el5) on file-server, and
use libnss-ldapd, libpam-ldap, auth-client-config
ldap-auth-client and ldap-auth-config packages to change client's user
authorization methods.

	But the problem is I do can get user authorization info from the ldap
server, but I can't get root level access rights from ldap server as
followed the steps here:
http://www.gratisoft.us/sudo/man/sudoers.ldap.html.

##################
My server configurations are:

[1]/etc/openldap/slapd.conf：
------------------------------
The sudoers.schema has been included and indexed:
include         /etc/openldap/schema/sudoers.schema
index sudoUser                          eq

[2]/etc/ldap.conf:
------------------------------
sudoers_base has been set:
sudoers_base ou=SUDOers,dc=file-server

[3]Some contents in ldap database:
------------------------------
# SUDOers, file-server
dn: ou=SUDOers,dc=file-server
ou: SUDOers
objectClass: top
objectClass: organizationalUnit

# %sysadmins, SUDOers, file-server
dn: cn=%sysadmins,ou=SUDOers,dc=file-server
objectClass: top
objectClass: sudoRole
cn: %sysadmins
sudoUser: %sysadmins
sudoHost: ALL
sudoCommand: ALL

(sysadmins is a group name that I created in my ldap server, what I want
is user in this group can get root level access rights.)
