[python-ldap] Problems with using SASL and unicode

[Luminita Moruz]

Hi,

I am trying to use python-ldap with SASL. but I am not able to get SASL
working when the username or password contain special characters. The code
is given below. Any help with this would be greatly appreciated.

# -*- coding: utf-8 -*-

import ldap
import ldap.sasl

def my_function(username, password):
    try:
        ldap_connection = ldap.initialize(LDAP_SERVER)
        ldap_connection.set_option(ldap.OPT_REFERRALS, 0)
        ldap_connection.protocol_version = 3

        auth_tokens = ldap.sasl.digest_md5(username, password)
        ldap_connection.sasl_interactive_bind_s("", auth_tokens)

    except ldap.INVALID_CREDENTIALS, e:
        print e

def main():
    u = u"user"
    p = u"pass"
    my_function(u.encode("utf-8"), p.encode("utf-8"))

This works just fine if the username and password do not contain any
special characters, but gives
{'info': '8009030C: LdapErr: DSID-0C0904F8, comment: AcceptSecurityContext
error, data 52e, v23f0', 'desc': 'Invalid credentials'} otherwise.

Thanks,
Luminita
