If you have a test environment (with PHP 8.1) to debug with we can walk through the steps of debugging the issue here to maybe speed up the process. You'd first need to un-phar the plugin by cding to your osTicket plugin directory on the webserver (eg. /path/to/osTicket/include/plugins/) and running the following command:

php -r '$phar = new Phar("auth-ldap.phar"); $phar->extractTo("./auth-ldap");'

This will create a new folder called auth-ldap/ within your /path/to/osTicket/include/plugins/ folder containing the un-phared contents of the plugin. Once you have this, login to the database, go to the plugin table, find the record for the ldap plugin, set the install_path to plugins/auth-ldap (basically just remove the .phar from the current value), set isphar to 0, and restart the webserver and PHP-FPM (if you're running it) to clear any file cache.

Now you will be running the un-phared plugin and you can add debug statements to the code that will reflect on screen or in your logs.

From here you can open include/plugins/auth-ldap/authentication.php file, go to the authenticate() method, and look for these specific lines.

Under the $r = $c->bind($dn, $password); line and above the if (!PEAR::isError($r)) line add the following statement:

error_log(print_r($r, true));

Once you make the changes please save the file, tail the error logs on the webserver, attempt to login as a User via LDAP, and see what gets logged in your error logs. I'm going to bet this will be a PEAR error containing an error from the bind attempt. If you don't see anything being logged then it seems it's not even attempting LDAP auth.

Please note that the log may be put in your webserver error logs or PHP error logs or even the general server logs. It just depends on how you have PHP configured. You can look at your PHP INI file to see where error logs are being stored.

Cheers.

      I appreciate you working with me. Last week we were on Spring Break so I had some cycles to spend on this. Unfortunately, I don't have time to spend right at the moment. I will try to get back to you. Thank you!

      Thank you for those tips - after debugging this (to some extent), I think the issue might be related to PHP 8.1.0 migrating from ldap resource to LDAP classes. So ldap result is replaced with LDAP\Result and ldap result entry is replaced with LDAP\ResultEntry. The same functions now return objects instead of resources. This seems to be causing issues in parsing search search results where checks using is_resource() are failing.

      Am I on the right track here?

          If that's the case how come I can use PHP 8.1 with LDAP with no issues?

          Cheers.

            That's a good question. I was able to track the LDAP logs and saw the search result being returned, but when the auth-ldap code was trying to convert the search results into Net_LDAP2_Entry objects, it was not able to convert them.

            When I added debugs, I got this error from the shiftEntry() method:
            " Unable to create connected entry: Parameter $entry needs to be a ldap entry resource! "

            When I printed the actual object it was trying to convert, it was of type LDAP\ResultEntry. That is what got me looking at PHP 8.1.

            I honestly don't know how its working for you. Sorry I could not help more with the debugging.

            BTW, if I try to hack it temporarily and accept the search result as a LDAP\ResultEntry object, I am able to successfully authenticate (the problem was when it was trying to retrieve the DN from the search result).

            I also found another minor issue with the configuration.php file in auth-ldap.phar - when we specify a port number in the ldap servers information (as host:port) in the instance detail screen, it assumes the port number is at most 4 digits, I think it needs to be adjusted to allow up to 5 digits.

                  I'm talking about this part:

                  BTW, if I try to hack it temporarily and accept the search result as a LDAP\ResultEntry object, I am able to successfully authenticate (the problem was when it was trying to retrieve the DN from the search result).

                  I'm curious to see what you did to authenticate successfully.

                    Nevermind...I feel SO stupid right now.. this ENTIRE time I forgot I had already made those changes to convert is_resource() to valid checks and that's why mine has been working... the reason I didn't know about the changes is because I was editing the raw plugin from within my normal core osTicket git not the osTicket-plugin git so it didn't track the plugin changes..

                    Your comment really helped me by making me question my own sanity and I can't thank you enough lol 🙌

                    Cheers.

                      Everyone,

                      We will have a pull request made and a new build of the plugin released soon that should resolve the user login issue.

                      Cheers.

                      Everyone,

                      Below is a custom build of the plugin until we make new releases. This has the PHP 8.1 support patches as well as a patch to fix a fatal error included. Just replace your current plugin build with this build (after unzipping of course).

                        That's because your issue is completely unrelated to this thread. Your issue is with LDAPS not connecting at all. This thread is about LDAP is able to connect but user authentication is not working.

                        Cheers.

                            Sigh, I have a similar issue using the LDAP plugin, inclusive of the one that @KevinTheJedi submitted. I installed it, configured it and it works fine for agent creation, but no matter what, the user accounts get access denied.

                            I have all of the recommended extensions installed as well.
                            I also checked the ost_user_account table and can confirm that the backend is ldap.client.pxxx

                            Is there anything else I can check to get this to work?

                            Regards.

                              Clear the cache/cookies and retest. Have them try a different browser/device. Make sure you restart the webserver and PHP-FPM (if you're running it) to clear any file cache. If you use a shared host ask them if there is anything else you need to do to clear any file cache. Most of the time PHARs are heavily cached so even if you replace the PHAR file it will still serve the cached version.

                              Other than that look into your logs on the AD server to see if their authentication attempts are actually going through and if they are successful or not.

                              Cheers.
