LDAP: providers dict does not have 'ldap'

I have a working AskBot system on CentOS 6.x, askbot version 0.7.53, so I have successfully used LDAP before. However, I am trying to install a completely new AskBot (not upgrade) on a different server, Ubuntu 16.04, askbot version 0.10.0, and I cannot get LDAP working on the new system.

I only want LDAP login and local login. I have turned off all others. I have the following settings:

  • Login provider settings: "Activate local password login" is checked
  • Login provider settings: "Activate ??? login" for AOL,Blogger,ClaimID,Facebook,etc. are all unchecked
  • LDAP login configuration: "Use LDAP authentication for the password login" is checked

I'm using runserver to debug. I can use pdb.set_trace() to gather more information, if that would help. When I try to login using my admin user (local login), it works fine. When I try to login using LDAP, I get a KeyError (see below). Note that if I hack the code to get past this error, thus allowing AskBot to create the new user in its tables, I do not hit the error again. It apparently only happens during the initial login via LDAP. But my hack is not usable; I just did it to see if the login would work.

@dccarson, could you try checking out the latest code from the Askbot master branch at github? https://github.com/ASKBOT/askbot-devel. I remember fixing some issues related to LDAP, but it might not have made it to the 0.10.0

@Evgeny : I have reconsidered my method and have decided to continue on the 0.7.x stream for now. I need to very quickly bring an askbot server back online. So, why, when I start out with a fresh virtualenv, do I get import errors? Shouldn't `pip install "askbot<0.8"` give me the **correct** versions of everything needed? First, I get an error importing `import_string` during the syncdb step. This is easy to hack, which is what I did because I need to get this working quickly. Now, when I try to run `python manage.py migrate askbot` I get an error importing `migrations`. According to answers I have read elsewhere, `migrations` is not in Django until 1.7. But why is `migrations` being used when pip should have installed the correct version of everything? I have tried many different approaches and every time, I hit errors. At ...(more)

@dccarson - it could be that errors occur because askbot did not fix upper version of dependency libraries - this can lead to the package breaking in the future. In the upcoming releases this will be fixed. Testing currently the 0.7.x branch for a fresh deployment, will post an update shortly.

I've test-deployed the latest commit from the 0.7.x branch of the github repository into an empty virtualenv, worked for me. I will pin the latest acceptable dependency versions to avoid the potential dependency incompatibility issue. @dccarson, lease let me know how ldap works with this version.

OK. Should I be waiting for an 0.7.56 version before I try again? If not, then can you give me the exact git command to use to get the version where you are pinning dependencies. I am not a git user.
