thanks to you I have made progress in my configuration and I no longer have the same error.
I have changed this like the documention (https://docs.osticket.com/en/latest/OAuth2/Microsoft%20Authorization%20Guide.html)

https://i.imgur.com/ZHezMrj.png

In the apache2 global conf : etc/apache2/apache2.conf i have changed AllowOverride none by AllowOverride All

Here’s my osticket conf

Now when I send the auth2 configuration, the browser ask me to authenticate to microsoft 365 then I have this error :

My scope is like this :

    That means you didn't add offline_access as an API Permission in the App Registration in Azure AD. You must also grant Admin Consent to all the API Permissions as well. Please go back and follow our documentation thoroughly.

    Cheers.

      Thanks KenvinTheJedi, I made a typing error: office_access instead of offline_access
      So now it's ok !

      Hi Everyone,

      I've worked with OSTicket Support and they suggested I ask in this forum. I'm having the same problem

      I've checked the .htaccess file and I have Rewrite and Override set. But still no luck. I've also installed a GUI on the CentOS 7 box that OSTicket lives on. Tested the OAuth directly from the server and still no luck.

      I enabled debug level logging for rewrite using the following:

      LogLevel alert rewrite:trace2

      Below is the logging message I received, but I'm not sure what to do to correct my issue. Can anyone help?

        Sounds like you have other Apache configurations blocking rewriting for this site. The main thing is making sure you have AllowOverride All in the site config.

        You can google “how to enable url rewriting for Apache centos7” or “Apache url rewriting enabled but not working” for further information.

        Cheers.

          Hi Kevin,

          I have confirmed that AllowOverride All is set on all conf files. I've checked multiple articles and I went from having not found to Internal 500 Error.

          When I get this message in the GUI. I see this in the /var/log/httpd/error_log

          '[Fri Dec 30 16:08:10.016201 2022] [rewrite:trace1] [pid 215986] mod_rewrite.c(470): [client XXX- - [X.X.X.X/sid#564f86685f60][rid#564f869571e0/initial] pass through /osTicket/api/auth/oauth2, referer: https://login.microsoftonline.com/

          any other ideas? I've insured AllowOverride All is in all config to the point that it broke OSTicket at first, but above is the closest I got. I also checked /var/log/messages but nothing helpful there.

          Thanks for any advice!

          Matt

            MattHaberer

            It’s saying AllowOverride is not allowed within the /var/www/html/osTicket/api/.htaccess file. So it seems like you edited the .htaccess files that osTicket ships with. You are not supposed to edit any of the osTicket files. Please restore these files to vanilla and retest.

            Cheers.

              I had the same issue and couldn't get the apache2 URL Rewrite to work in Ubuntu . The thing that finally fixed it was enabling it in the main apache config, not just the site config.

              Steps:
              1) sudo nano /etc/apache2/apache2.conf
              2) Find

              <Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

              3) replace AllowOverride None with AllowOverride All

              <Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
</Directory>

              4) Restart apache
              sudo systemctl restart apache2

              System Specifics:

              osTicket Version 	1.17-git (?) — 8fbc7ee is available

              Hi, I too am getting the error.
              However, in my case the directory / file don't actually exist on the server
              The plugin is enabled, and has been for some time.

              I get this after setting up the Auth:

              Should I remove and re-install the Plugin?
              Currently running Version 1.17.2
              Centos V7, using httpd that ships with Centos

              Is it possible I have missed a step somewhere during the Plugin install?

                Androids

                URL Rewriting is not enabled on your webserver. The file doesn't actually exist which is why you need URL Rewriting installed/enabled so that our .htaccess files can rewrite and direct the URL to the proper destination.

                Cheers.

                    Thanks, it was already enabled - (/etc/httpd/conf.modules.d/00-base.conf in Centos)
                    It is working now regardless.

                    Just to add to this;
                    [root@tickets /]# httpd -M|grep write
                    rewrite_module (shared)

                    In (Centos) /etc/httpd/conf/httpd.conf
                    <Directory "/var/www/html/osticket"> # YOUR EXACT directory
                    AllowOverride All
                    Options FollowSymlinks
                    Require all granted
                    </Directory>

                    systemctl restart httpd

                    That worked for me - Explicitly defining the osticket directory was the key

                    Hi, I've been getting the same error. Before starting with URL rewrite and other suggested fixes, i wanted to know if it is necessary to setup remote mailbox and outgoing. I don't have them setup and i just want to implement simple OAuth with Microsoft login for which i have followed the necessary steps show in the authentication guide for Microsoft in osticket official docs.

                          Hi, I have the same problem, when I authenticate with office.

                          I have apache modrewrite enabled.
                          In my virtual host as well as in apache2.conf I have the following

                          In the virtual host

                          Can you help me

                            Rookye23

                            I can't say for certain but it's probably due to your virtual site config rules. I would clear all the custom rules, make it default, reload/restart the webserver so the changes are applied, and retest.

                            Cheers.

                                Hello KevinTheJedi

                                This is what I have configured in the plugin

                                And I have left the vhost as clean as possible.

                                I have modrewrite enabled, which I'm missing

                                in my directories I don't have the path to api/auth/oauth2

                                I might be configuring the wrong redirect url in Azure ?.

                                Thanks

                                    Rookye23

                                    No that’s correct. The api/http.php file redirects the request to the proper channels. Definitely seems like a setup issue as you have a custom port but don’t have the site config setup correctly for that.

                                    Cheers.
