encodings while modify AD with linux-client

[Ingo S. <st...@un...>]

Hello

I've got some encoding-trouble accessing Active Directory with python-ldap=
=20
(slightly modified 2.0.6) on linux (openldap-client 2.1.30).

I can modify a container-description using umlauts without an Error/Excepti=
on:

[..]
lo.simple_bind_s(login_dn, login_pw)

modlist=3D[(ldap.MOD_REPLACE,"description",[u"hall=F6le".encode('ISO-8859-1=
')])]
lo.modify_s("CN=3Dmoreusers,CN=3DUsers,%s"%ldap_base,modlist)
[..]

Search for this container or view it in windows will result the description=
=20
"hallle" (umlauts are "cutted"). Using an different encoding (different fro=
m=20
ISo-8859-1/Latin) will result in an exception, like this one with unicode:

  File "/usr/lib/python2.3/site-packages/ldap/ldapobject.py", line 298, in=
=20
modify_s
    msgid =3D self.modify(dn,modlist)
  File "/usr/lib/python2.3/site-packages/ldap/ldapobject.py", line 295, in=
=20
modify
    return self.modify_ext(dn,modlist,None,None)
  File "/usr/lib/python2.3/site-packages/ldap/ldapobject.py", line 268, in=
=20
modify_ext
    return=20
self._ldap_call(self._l.modify_ext,dn,modlist,serverctrls,clientctrls)
  File "/usr/lib/python2.3/site-packages/ldap/ldapobject.py", line 94, in=20
_ldap_call
    result =3D func(*args,**kwargs)
TypeError: ('expected a string in the list', u'hal\xf6le')

It is documented that Active Directory uses ISO-8859-1 and not utf8 (like=20
Openldap an others).=20

So, is this a python-ldap or openldap-problem (I know, great chanceto start=
 an=20
AD-Flamewar)? Any experiences/solutions?

Thanks!
