Configure LDAP authentication

I can see a few people seem to have had success setting up askbot to authenticate against active directory but I'm having trouble with it, could anyone clarify how these fields should be used:

LDAP service provider name: I tried "Active Directory"

URL for LPAP service: I tried "ldap://"

Explain how to change pwd: left blank

With these settings I get an Internal Server Error, and nothing inserted into the log.

I've been fighting LDAP for a bit here, and found a couple tricks that helped me out.

First, if your LDAP requires authentication, just add this to your

LDAP_LOGIN_DN = 'someldapuser'

LDAP_PASSWORD = 'somepassword'

Fill in the ldap read username/password.

Also, make sure to use the current git repository instead of the PyPi build, as it is out of date. Make sure that your has ldap, for me even when using git to build I had the out of date version. You can tell as the final setting will be indentica.

After that, go ahead and login with your admin user. Go into settings and configure your LDAP settings, then configure it again under external keys... I'm not sure which takes precedence. Finally, go into login providers and uncheck everything. Then recheck "Always display local login form" and "Activate Local Password Login". Don't worry, that's just going to force it to only use LDAP.

From there, you should be ok. I edited the log level in to be info for the purpose of getting all configs set correctly.

Hope this helps some others!

Koni's answer does not solve the problem because it does local login, not ldap.

I can't find any good explanation of the use of ldap on the site. Does it work or not? (I think not)

Which version of LDAP protocol are you using? Askbot is hardcoded to work with v3. LDAP support was contributed by somebody else and we have not tested it thoroughly yet. If you have ability to test and debug - please look at the module askbot.deps.django_authopenid.backends.

Evgeny's avatar Evgeny (2012-06-23 18:20:05 -0500) edit

Looked at the protocol again - it turns out we connect to LDAP without authentication, and if your directory does not allow anonymous lookup of data - it won't work. Also - please do check your log/askbot.log all LDAP errors are logged. Please tell me which one do you have?

Evgeny's avatar Evgeny (2012-06-23 19:20:09 -0500) edit

I can connect with jxplorer using v3. But I can't make it work with askbot. We have authentication as mandatory, so we can't use it anonymously. There are no logs on the log folder. I am going to debug backends to see what happens

What is the point of using ldap on the login system if you dont use authentication?

enrique's avatar enrique (2012-06-25 10:53:41 -0500) edit

On, on the method "ldap_authenticate", I connect to the ldap server and on the line "res = ldap_session.search_s(askbot_settings.LDAP_BASEDN, ldap.SCOPE_SUBTREE, user_filter, None)" fails throwing an exception "{'desc' : 'Bad search filter'}" It looks like its searching on a field called desc which does not exists. It should be "cn" not "desc"

I got it working here:

I'm not sure if this will cover all LDAP configurations, but it's working for me now. You'll need to adjust the appropriate login configuration items so that the openauth items do NOT display, and to setup the ldap configuration values in settings/EXTERNAL_KEYS.

Only three files need to be updated:

  • deps.django_authopenid.views
  • deps.django_authopenid.backends
  • conf.external_keys
