Comments in src/backend/libpq/auth.c say: (after successfully finding
the final DN to check the user-supplied password against)
/* Unbind and disconnect from the LDAP server */
and later
/*
* Need to re-initialize the LDAP connection, so that we can bind to
* it with a different username.
*/
But the protocol actually permits multiple subsequent authentications
("binds") over a single connection.
So, it seems like the whole connection re-initialization thing was
just a confusion and can be safely removed, thus saving quite a few
network round-trips, especially for the case of ldaps/starttls.
