connect() is always done synchronously.  Any idea when this will be
fixed?
It's actually not considered a bug.  ldap_sasl_bind(3) is async
in doesn't wait for the LDAP response.  There is no LDAP restart
API, as would be needed if the API didn't block on various
system calls.
Why is that required here?
ldap_sasl_bind()
  ldap_result()
  if (timeout) {
    ldap_abandon()
    if (just_return_on_error) {
      return error
    } else {
      do_something_else
    }
  }
To restart a bind, just abandon and bind again.
There was a discussion recently on the subject (look in hte ITS).  A 
bind cannot be abandoned as per RFC 4511-19; you need to ldap_unbind_ext 
and recreate a fresh connection.

I am not all that familiar with the LDAP API, so forgive me if I'm
way off base here.
