This does not sound secure:
The user can easily use a modified copy of your script.

You probably want to use

http://www.python-ldap.org/doc/html/ldap.html#ldap.LDAPObject.simple_bind_s

Check whether password is non-zero before because most LDAP servers consider
an empty password as anon simple bind even if the bind-DN is set.
