#superuser_name = omneon

8. Create a symbolic link between the two LDAP configuration files as follows:
mv /etc/openldap/ldap.conf /etc/openldap/ldap.conf.old
ln -s /etc/ldap.conf /etc/openldap/ldap.conf
9. Type the following to test the configuration:
id diradmin
where “admin” is a user who is only in ldap and not in the local /etc/passwd file.
You should see the following if the configuration is set up properly:
uid=1000(diradmin) gid=20(games) groups=20(games),80(admin)
If you see the following output, LDAP is not configured properly, and you must trace the
problem:
id: diradmin: No such user
10. Restart the omcld service by typing the following:
service omcld restart
11. Run mdsclientn as shown below to verify that you can authenticate successfully against any
valid user account in the Open Directory:
/opt/omcld/bin/mdsclientn localhost
sess get-users
sess get-groups
sess auth [username] [password]
The following is a sample output from mdsclientn:
[root@mds3 ~]# /opt/omcld/bin/mdsclientn localhost
