hi friends

I have one small doubt on Ldap, do we need to install ldap in 7.2 version or it already have a ldap package on cd? One more thing i want to know is that do we need to creat schema  in ldap database or it is already have a default schema  in Ldap because when i try to enter any entry on ldap database using ldif file then it gives an error of object class not found.

please help me.

thanks in advance
