More on composite rdns ...

[Pierangelo Masarati <masarati@aero.polimi.it>]

In ldap_dn2ufn there's no handling of composite RDNs

    type=value[+type=value]

and there's no mention of its conversion neither in rfc1781
(too old) or in rfc 2253 (maybe ufn was not an issue).
I modified ldap_dn2ufn to handle such case. The behavior
is very simple:

- attributes are still stripped off
    (including those of composite rdns)
- rdns are still separated by commas
- values withing a rnd are separated by ' + '.

Example:

# Pierangelo Masarati + ando, mbdyn, org
dn: cn=Pierangelo Masarati+uid=ando,dc=mbdyn,dc=org

I'll commit this change if nobody disagrees; suggestions for
better separators are welcome, however.

Pierangelo.
