Authentication with ldap

The following python script demonstrates the authentication with ldap:

import ldap


def authenticate(address, username, password):
    conn = ldap.initialize('ldap://' + address)
    conn.protocol_version = 3
    conn.set_option(ldap.OPT_REFERRALS, 0)
    try:
        result = conn.simple_bind_s(username, password)
    except ldap.INVALID_CREDENTIALS:
        return "Invalid credentials"
    except ldap.SERVER_DOWN:
        return "Server down"
    except ldap.LDAPError as e:
        if type(e.message) == dict and e.message.has_key('desc'):
            return "Other LDAP error: " + e.message['desc']
        else: 
            return "Other LDAP error: " + e
    finally:
        conn.unbind_s()
    return "Succesfully authenticated"


print(authenticate('192.168.10.254', 'administrator@trainingX.net', 'yourPassword'))
