Description

I’ve added and setup the LDAP plugin (see picture), following what was shown here . But when I go to login to the web portal I get a http 500 error and the below is the apache error log that coincides with the login attempt. I had had the LDAP plugin installed before, but uninstalled and reinstalled following this post

If I’m reading the code correctly, it appears that the php ldap module is not installed on your ubuntu box. The fog installer should do this by default.

[Tom Elliott]

Unless it is an update. Please try installing manuallt

[iyoung]

php-ldap was not installed. I’ll restart and see what happens. I also looked in /opt/fog/.fogsettings and didn’t see php-ldap or a package that depends on it.

[george1421]

@iyoung FWIW: You only need to restart apache when you update php

[george1421]

You will probably have other issues since you did not supply a bind DN. AD does not allow blind binds via ldap.

[iyoung]

Success! I was able to login with a domain user, after installing php-ldap, without issue.

[george1421]

@iyoung Ok so now the question is why didn’t the installer install that for you?? (just an open question).

That’s great it worked for you, Tom spent quite a bit of time working out the details on that plugin to make it a bit more universal.

Marking issue as solved.

@george1421 @tom-elliott I’ll spin up a host to see if it’s an issue on fresh installs of 1.3.0.

I had this working last week but it’s mysteriously stopped working now. I didn’t spend a lot of time looking into it, just giving this tidbit of info here.

[iyoung]

Just looking at FOG installing now, I can see php7.1-ldap in the “Packages to be installed.” The only things I changed before installing FOG were installing aptitude and ssh-server.

OS: Ubuntu 16.10 Server
FOG: 1.3.0 (SVN 6051)

[Tom Elliott]

@iyoung I think the difference was your “fresh” install knows to install ldap already. The upgrade, however, doesn’t.

[iyoung]

@Tom-Elliott I looked at the creation date of my main FOG server and it looks like it was created on 09/15/2016, and I know that I went right to trunk when I installed FOG. I skimmed this thread which is, for the most part, newer than that. Was php-ldap added more recently?

[Tom Elliott]

@iyoung yes I think october ish timeframe

[george1421]

@iyoung That is most likely the case, the php-ldap module, before the thread, was a user responsibility to add it in and not provided by the fog installer (if I remember correctly). Once Tom updated the ldap plugin it was logical that if The FOG Project supplied the plugin that the installer should install all required modules.

@iyoung Test completed. LDAP plugin added and test login succeeded.
