[turba] 1.2RC2 distribution lists & LDAP Sources

[Adam Tauno Williams]

With 1.2RC2 and an LDAP source, every object in the DSA that matches the filter
and is beneath the root shows up as a potential distribution list to add objects
too.  This makes the page very slow, despite being rather wrong headed
behaviour.  With SQL sources one can specify a '__type' field,  but how can one
achieve the same against an LDAP source without using specific Turba schema?  IS
there to make objects '__type' 'Contact' by default?

    'title' => 'Morrison Enterprise Directory (Persons)',
    'type' => 'ldap',

        'port' => 389,
        'root' => 'ou=People,o=Morrison Industries,c=US',
