ldap_rename

[Michael L Torrie <torriem@cs.byu.edu>]

I'm using openldap 2.0.9 and I thought I was using ldapv3.  But php claims
that openldap doesn't support the rename ability (which would indicate I'm
really using only ldapv2 protocol).  How can I tell which protocol is
being used and if openldap supports rename, how do I get slapd to use
ldapv3 so I can use php's ldap_rename function?

thanks,

Michael
