It sounds  to me like you want a relay database.

If you are still talking about rootdn: No that is not possible.
You can have only one rootdn per database.

But you can give any LDAP user the same privileges by setting the ACLs
propperly.

Please consult man slapd.access or the admin guide.

Thanks Ulf for the quick response and detailed explanation. So do I need to have two openldap servers running on Red Hat Enterprise Linux release 8.8 (Ootpa)

For example

corporate.mydomain.com

dn: cn=admin,dc=corporate,dc=mydomain,dc=com on openldap on port 389

checker.mydomain.com

dn: cn=admin,dc=checker,dc=mydomain,dc=com on openldap on port 390 

Please guide me. Thanks in advance.

Best Regards,

Kaushal
