[Fedora-directory-users] FDS- Adding New attribute and object class?

[Hariharan R]

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?

  Is there is any formal method to adding it(without using FDS console)?

  Pls advice me.
