ldapom's Issues

Saving without modifications yields LDAP Syntax Error

Reported by @maethor in unrelated issue #32

ldapom.error.LDAPError: Invalid syntax

Doesn't happen on my machine. We should investigate.

COPYING file missing

Would you please add COPYING file to make the licensing terms clear. That'd be super.

jpegPhoto attribute has no value

Hi,

When I retrieve a user, the jpegPhoto attribute is fetched but stay is empty even if it is set in the LDAP.

>>> entry = LDAPEntry(ldap, "cn=guillaume,dc=sysnove,dc=fr")
>>> entry.fetch()
>>> entry._fetched_attributes
{<LDAPAttribute userPassword>, <LDAPAttribute objectClass>, <LDAPAttribute mailAlternateAddress>, <LDAPAttribute mailQuotaSize>, <LDAPAttribute accountStatus>, <LDAPAttribute jpegPhoto>, <LDAPAttribute mailForwardingAddress>, <LDAPAttribute sn>, <LDAPAttribute mail>, <LDAPAttribute cn>, <LDAPAttribute givenName>}
>>> entry.jpegPhoto
set()

I'm using ldapom with python3.3.

Thanks.

Disable attribute type mapping for less connection overhead

Hi,

i was using ldapom 0.9.x a year ago and it was working great.
Now, after upgrading (and changing some parameters in LDAPConnection), the library doesn't work anymore, every connection attempt fails with LDAPNoSuchObjectError..

I figured out that ldapom tries to query in cn=subschema which does not necessarily exist.
I am using ldapom with a lot of LDAP connections (aka logins) per second and am concerned why it wants to fetch the complete schema on every connect. Can this be disabled again?
Also, as i mentioned, the schema doesn't have to be in cn=subschema (for me it is in cn=schema)...

Unfortunately, i had to revert back to 0.9.4 which happens to work very well for me :(

Cheers,
Sebastian

Binary attributes are cut on \x00

Hi,

I have a problem when I set a binary attribute with a value containing "\x00" (Null Character).

>>> user.jpegPhoto = Avatar.generate(8, user.mail)
>>> user.jpegPhoto
b'\xff\xd8\xff\xe0\x00\x10JFIF\x00\x01\x01\x00\x00\x01\x00\x01\x00\x00\xff\xdb\x00C\x00\x08\x06\x06\x07\x06\x05\x08\x07\x07\x07\t\t\x08\n\x0c\x14\r\x0c\x0b\x0b\x0c\x19\x12\x13\x0f\x14\x1d\x1a\x1f\x1e\x1d\x1a\x1c\x1c $.\' ",#\x1c\x1c(7),01444\x1f\'9=82<.342\xff\xdb\x00C\x01\t\t\t\x0c\x0b\x0c\x18\r\r\x182!\x1c!22222222222222222222222222222222222222222222222222\xff\xc0\x00\x11\x08\x00\x08\x00\x08\x03\x01"\x00\x02\x11\x01\x03\x11\x01\xff\xc4\x00\x15\x00\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x06\xff\xc4\x00!\x10\x00\x01\x02\x05\x05\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\x00\x02\x03\x04\x11\x121\x05\x13!BQa\xff\xc4\x00\x15\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x06\x07\xff\xc4\x00\x17\x11\x00\x03\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\x021\xff\xda\x00\x0c\x03\x01\x00\x02\x11\x03\x11\x00?\x00\xa5\x898\x1f\xa7B\x95\xdb \xb1\xd5\xbe\xf3C\x9e\xbe\xf3\x9f\x81\x11\x14\xd2\xad\xd6\x85\x1boO\xff\xd9'

>>> user.jpegPhoto
b'\xff\xd8\xff\xe0'

In connection.py, line 391, after doing strval = ffi.new("char[]", value):

>>> strval[4]
b'\x00'

This must cause a problem in CFFI, because \x00 means "end of string" in C.

What do you think ? Can I escape theses bytes ?

Thanks.

KeyError upon LDAPConnection instantiation

When connecting to an LDAP server on a remote CentOS machine I receive the following error:

>>> import ldapom
>>> c = ldapom.LDAPConnection(uri='ldap://auth-1.example.io', base='dc=example,dc=io', bind_dn='cn=Manager,dc=example,dc=io', bind_password='password')

Fetch attributes in _search() ?

Hi,

I don't understand what is the point of having the fetch() method separated from _search(), and more precisely why entry._fetched_attributes is not set by the _search() method.

I retrieve objects with search(). If I want to update them, I have to fetch each object found, one by one. Obviously, this cause some performance problems. Setting entry._fetched_attributes in _search() should solve this problem.

Thanks.

Unicode need string or buffer, not list

Hi,

When I try to print node.objectClass, I got this error message:
TypeError: coercing to Unicode: need string or buffer, list found

I checked the source code. My ldap attributes for objectClass is a list like this:
'objectClass': ['top', 'person', 'organizationalPerson', 'user']

Therefore, when I try to print node.objectClass, the list type will pass to unicode function in:
ldapom.py", line 379, in unicode
return unicode(self._values, "utf-8")

This causes a type error for unicode.
Could you fix this?
Thanks

LDAP "invalid syntax" when setting attribute with previous value and saving

Hello,

I'm trying to migrate my webldap app (https://github.com/FedeRez/webldap) to Python 3 and ldapom 0.11. OpenLDAP version is 2.4.31 (Debian Wheezy).

Unfortunately, I get an error when basically doing the following:

me = l.get_entry(binddn)
me.cn = old_value
me.save()

where { old_value } is the same as me.cn. This does not depend on the kind of attribute it seems.

Traceback (most recent call last):
  File "/home/bertrand/env/ldapom/lib/python3.4/site-packages/django/core/handlers/base.py", line 115, in get_response
    response = callback(request, *callback_args, **callback_kwargs)
  File "/home/bertrand/web/federez_ldap/accounts/views.py", line 48, in _view
    return view(request, l=l, *args, **kwargs)
  File "/home/bertrand/web/federez_ldap/accounts/views.py", line 124, in profile_edit
    me.save()

    return func(lc, *args, **kwargs)
  File "/home/bertrand/env/ldapom/lib/python3.4/site-packages/ldapom-0.11.0-py3.4-linux-x86_64.egg/ldapom/connection.py", line 430, in save

    raise error.LDAPError(error_string)
ldapom.error.LDAPError: Invalid syntax

No error occurs if the LDAP attribute is different (ie. the user chooses a new cn value). I've been unable to reproduce this issue with the test suite, maybe because the OpenLDAP version is different?

With some of the older commits, I get a "Constraint violation" error instead.

Doesn't fetch memberOf attribute

Hi,

I can't find a way to fetch the "memberOf" attribute of an entry. The attribute is present in entry._attributes, but not in entry._fetched_attributes.

>>> entry = LDAPEntry(ldap, "cn=guillaume,dc=example,dc=fr")
>>> entry.fetch()
>>> entry._attributes
{<LDAPAttribute jpegPhoto>, <LDAPAttribute userPassword>, <LDAPAttribute cn>, <LDAPAttribute sn>, <LDAPAttribute mail>, <LDAPAttribute accountStatus>, <LDAPAttribute givenName>, <LDAPAttribute mailQuotaSize>, <LDAPAttribute mailAlternateAddress>, <LDAPAttribute objectClass>}
>>> entry._fetched_attributes
{<LDAPAttribute jpegPhoto>, <LDAPAttribute userPassword>, <LDAPAttribute cn>, <LDAPAttribute givenName>, <LDAPAttribute accountStatus>, <LDAPAttribute mail>, <LDAPAttribute mailQuotaSize>, <LDAPAttribute sn>, <LDAPAttribute mailAlternateAddress>, <LDAPAttribute objectClass>}
>>> entry.memberOf
set()
>>> entry._attributes
{<LDAPAttribute jpegPhoto>, <LDAPAttribute userPassword>, <LDAPAttribute memberOf>, <LDAPAttribute cn>, <LDAPAttribute sn>, <LDAPAttribute mail>, <LDAPAttribute accountStatus>, <LDAPAttribute givenName>, <LDAPAttribute mailQuotaSize>, <LDAPAttribute mailAlternateAddress>, <LDAPAttribute objectClass>}
>>> entry._fetched_attributes
{<LDAPAttribute jpegPhoto>, <LDAPAttribute userPassword>, <LDAPAttribute cn>, <LDAPAttribute givenName>, <LDAPAttribute accountStatus>, <LDAPAttribute mail>, <LDAPAttribute mailQuotaSize>, <LDAPAttribute sn>, <LDAPAttribute mailAlternateAddress>, <LDAPAttribute objectClass>}

Do I have to do something special ? Is it a bug in LDAPConnection._raw_search() ?

I'm using ldapom with python3.3.

Thanks.
