Hi friend,
I tried to configure a ldap server with the help of
file:///root/ldp/Quick_HOWTO_%20_Ch31_%20_Centralized_Logins_Using_LDAP_and_RADIUS.htm
&
http://www.redhat.com/docs/manuals/e...-ldap-pam.html

links.
But I failed to cross the step of ldapadd & domainsearch:

[root@bigboy tmp]# ldapadd -x -D "cn=Manager,dc=example,dc=com" \
-W -f /etc/openldap/example.com.ldif
[root@bigboy tmp]# ldapadd -x -D "cn=Manager,dc=example,dc=com" \
-W -f /etc/openldap/root.ldif
[root@bigboy tmp]# ldapadd -x -D "cn=Manager,dc=example,dc=com" \
-W -f /etc/openldap/ldapusers.ldif

Theses commands returning with an error msg. & ldapsearch -x -b 'dc=example,dc=com' \
'(objectclass=*)'
this command is giving an output of 0 success.

But dns is working in this machine very fine.

Can you please guide me in proper way.

And have you considered telling us the *content* of that error message?

Without having any more detail, two typical causes come to mind:

1. You'll have to add the top node "dc=example,dc=com" using slapadd rather than ldapadd. (And turn OFF slapd before doing that).
2. Check the file permissions of your database files/directories.
