django-auth-ldap "an integer is required" error - django

Question

Using Django 1.4 and django-auth-ldap 1.1, I'm trying to configure my web app to authenticate users against an LDAP service. On supplying the correct login credentials in the login form, I'm getting this error :-
TypeError at /login/
an integer is required

Exception Location: /usr/lib/python2.6/dist-packages/ldap/functions.py in _ldap_function_call, line 57

Answer 1

Your LDAP server is complaining about one of the key/value pairs in your AUTH_LDAP_GLOBAL_OPTIONS. Make sure you're using the ldap.OPT_* constants as the dictionary keys.
