Did you consider to use OATH-LDAP's schema?
That's the most flexible way of doing it which is appreciated.
Furthermore I'm very paranoid regarding security of shared secrets. In
current OATH-LDAP they are asymmetrically encrypted with only an
*external* component having access to the private key(s).
It would be nice to join forces developing something which is more
integrated with OpenLDAP though.
Ciao, Michael.
