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

sudoers_base has been set: sudoers_base ou=SUDOers,dc=file-server

(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.) ##################

So, any ideas of you? Please let me know, thanks very much in advance!
Did you confirm that when you run 'sudo -l' or similar, sudo is actually doing an LDAP search?
Did you enable debugging in the sudo LDAP support, by e.g. adding:
sudoers_debug 2
to /etc/ldap.conf ?
Can you provide 'sudo -l' output?
