Splits the DN returned by ldap_get_dn() and breaks it up into its component parts. Each part is known as Relative Distinguished Name, or RDN.
The distinguished name of an LDAP entity.
Used to request if the RDNs are returned with only values or their
attributes as well. To get RDNs with the attributes (i.e. in
attribute=value format) set
with_attrib to 0
and to get only values set it to 1.
