Hello,

I needed to get LDAP protocol version 3 working to get the binddn/bindpw options to work with openldap 2.2.11. I made a source patch to add a 'protocol_version' option in the maildropldap.config file. It defaults to version 2 if not specified.

I've attached a patch that will make the few modifications needed to the source tree. To apply the patch put it in the root of the maildrop-1.6.3 source tree, then run

# patch -p0 < maildrop_ldap_protocol.patch

I hope someone will consider adding it to the source tree; it should be useful to others as well. Thanks...
