Django Auth LDAP - NO_SUCH_OBJECT

Question

Today out of the blue my WEBApp started failing in the login. I am authenticating the users against LDAP. The Web App is hosted on a Windows 2003 Server with Django 1.6.1 and Apache 2.2 and mod_wsgi.

The error is

ERROR : 18/02/2015 01:52:17 PM : result(3) raised NO_SUCH_OBJECT({'info': "0000208D: NameErr: DSID-031001CD, problem 2001 (NO_OBJECT), data 0, best match of:\n\t'OU=EU,DC=osud,DC=corp'\n", 'matched': 'OU=EU,DC=cosud,DC=corp', 'desc': 'No such object'},)

I checked on http://docs.oracle.com/cd/E19957-01/816-5618-10/netscape/ldap/LDAPException.html#NO_SUCH_OBJECT and it says this

NO_SUCH_OBJECT

public static final int NO_SUCH_OBJECT
(32) The entry specified in the request does not exist.

At http://www.python-ldap.org/doc/html/ldap.html it says this

exception ldap.NO_SUCH_OBJECT
The specified object does not exist in the directory. Sets the matched field of the exception dictionary value.

But none of these realy apply in the situation. And after like 2 hours the login started working again. There was a restart of Apache Server in between but not sure if that can contribute to this.

What else can i do to get to the bottom of this issue? Any more logging that can be added to get more information?

I had the same problem and it was related to my base DN: OU=name,dc=some,dc=random,dc=organization

The CN of my OU got changed and my python script started to show the same error message:

ldap.NO_SUCH_OBJECT: {'info': "0000208D: NameErr: DSID-031001CD, problem 2001 (NO_OBJECT), data 0, best match of:\n\t'DC=some,DC=random,DC=organization'\n", 'matched': 'DC=some,DC=random,DC=organization', 'desc': 'No such object'}

Try running the query using some LDAP client (ldapsearch and Apache Directory Studio are my favorites) and compare the results.

I hope it helps,
