Hai, I want to add a new (user defined) attribute and object class to the Fedora directory server without using the console?

How i can do it?

I tried to add new attribute/object class through schema/00core.ldif file. After that i restarted my directory server,fine, my FDS recognizes the new attribute and object class.

Is it the correct way of doing it?

You should make your own files, instead of adding to existing files.

Also, you should use your own OID namespace, instead of using the ones in existing files. You can apply for an OID namespace for your organization, at iana.org.
