The server has a valid Let's Encrypt cert. Verified w/ multiple browsers. Unclear why this error is happening. The links are to the libcurl docs, which state: The remote server's SSL certificate or SSH fingerprint was deemed not OK.

If I find anything I'll post more info.

Looks potentially related to not sending intermediate certs. Not sure if I have to set certificate paths in PHP, I thought ACME/Let's Encrypt handled it. Still looking.

What versions do you have installed?

  • osTicket
  • oauth2 Plugin
  • PHP

Are you running the phar version of the oauth2 plugin?

Also try rebooting the server or running IISRESET from an elevated PowerShell prompt

    Rebooted server, no change: invalid_client
    Versions:
    osTicket (v1.17-rc4)
    Oauth2 Client 0.3
    PHP 8.1.10
    Windows Server 2019 Standard
    IIS 10.0.17763.1

    Not sure on phar or not, I didn't actually install the plugin, someone else did. I can confirm though.

    Ah, the plugin is now on v0.6
    Please update it and test again.

    So latest plugin version seems to be 0.5, and we're using the phar version. But using the new plugin throws a 500 and the modal window doesn't populate. To get 0.6, do I need to compile myself from the github repo?

    Any ideas?

      Swapping back to the old plugin doesn't resolve it. I'm going to replace all of the core files and start fresh.

      At the moment yes; when stable is released the plugin on our website will be updated. You can actually download the raw folder/files from github, put the auth-oauth2 folder in the include/plugins/ directory, go to the database and go to the plugins table, change the install_path from plugins/auth-oauth2.phar to just plugins/auth-oauth2, update isphar from 1 to 0, and you should be good.

      Cheers.

          KevinTheJedi Is this the updated plugin?
          https://github.com/osTicket/osTicket-plugins/blob/develop/auth-oauth/plugin.php
          The version says .1. I tested again with OAuth2 plugin 0.3, I can click the edit configuration just fine. If I uninstall it, and install 0.5 from the website, I receive 500 errors and a blank modal (no php or IIS errors that I can see). I'll gladly try what you recommended but I don't see 0.6 listed anywhere.

              KevinTheJedi This guide worked out for me. After a day's worth of struggle and fighting with everything from having the right PHP version installed all the way to getting a successful connection to outlook.office365.com's IMAP service (on port 993) via the Microsoft OAuth2 authentication (plugin version 0.5), I wanted to leave a few notes for the next guy that may be struggling with this:

              1. If you're on PHP 7.x and osTicket 1.15.8, get PHP 8.0 working first. Specifically 8.0. Upgrade to osTicket 1.16.3 by copying the contents of the "upload" directory over the contents of the existing 1.15.8 installation. As in a folder merge, overwriting any existing files. Update your filesystem permissions as needed if you are doing this through WinSCP as root (www-data or whatever webserver user needs permissions)

              2. Once you can verify that 1.16.3 is working (after going through the upgrade in the web interface) it's time to do the same thing with the 1.17 RC4 "upload" directory. Merge everything with the 1.16.3 installation overwriting all conflicting files. This is one of my many struggles. Apparently a fresh install of 1.17 RC4 does not work with the database still having data from 1.16.3? After that merge/copy/overwrite, be sure to update file permissions as needed.

              3. Unsure how this goes on Windows servers but for my case in a Debian 11 install with apache2, I had to tell apache2 to read the .htaccess files and enable the rewrite module. In the apache2.conf file, there might be a few lines that say "AllowOverride None". Those lines need to read "AllowOverride all". You also need the rewrite module enabled, it's usually enabled via "a2enmod rewrite".

              4. Follow this guide I am replying to exactly. (https://github.com/osTicket/docs/blob/3b6b623c026c15bb267e404a4afd72b19d29f035/OAuth2/Microsoft%20Authorization%20Guide.rst) Meaning create a new Azure app. I believe my issue was that I had created my Azure app a while back and something was different about the JSON that comes back from the user details "/me" endpoint.

                Hi guys, we are now two days out from the Oct 1 basic auth cutoff, do we yet have a date for 1.17 stable release? Additionally when configuring in our environment, attempting to configure the OAuth2 plugin always requests admin consent, and never successfully configures. Is this a known issue? Cheers.

                  I get the same thing. I have followed the guide you have linked Kevin but each time I configure the email account I get taken through the microsoft authentication process which completes then I am returned to our osticket landing page. I have to navigate to the /scp section then I check the email setup and it's still unconfigured with no green banner to say it's setup nor a red error message.

                      We had the same issue when setting this up. We found that this was caused due to not having the App Registration setup for Multitenant.

                          I did have it set that way originally but the new documentation https://github.com/osTicket/docs/blob/3b6b623c026c15bb267e404a4afd72b19d29f035/OAuth2/Microsoft%20Authorization%20Guide.rst showed it as single tenant. I've set it back to multi-tenant and unfortunately I'm now stuck with an issue that's being talked about here - https://forum.osticket.com/d/101542-oauth2-plugin-error. Unfortunately i'm having issues building the plugin myself and as a non-developer i'm finding it tricky to figure out so i'll just have to follow the conversation.
