[turba] pgpPublicKey and LDAP

[Volker Then]

Hello,

recently I switched my addressbook to LDAP. Is there a way to store PGP 
information in the LDAP directory? It seems that IMP gets the PGP 
information only from the localsql addressbook. sources.php.dist says

// These are not stored on the LDAP server.
        'pgpPublicKey' => 'object_pgppublickey',

But where is that information stored if not on the LDAP server? This is 
somehow confusing, because when adding a new contact to the LDAP 
directory the field "Public PGP Key" appears anyways, but after putting 
in some information the server responds with "(17) Undefined attribute 
type."

Is there some sort of workaround? I would like to get rid of the MySQL 
part of turba.

Thanks

Volker
