OAuth2 "No input file specified"

KevinTheJedi

Looks fine to me. That error simply means url rewriting is not allowed or is being blocked or something. Some people have success by modifying the api/.htaccess file and updating the [L] to [R,L]. Make sure you reload Apache and PHP-FPM is you’re running it.

I did try updating the [L] to [R,L] in the api/.htaccess file. But once I input the Microsoft email credentials I am redirected to localhost/osTicket/. Could there be another issue with the api/.htaccess or httpd.conf file?

Any suggestions on how to troubleshoot if URL rewriting is functioning correctly?

No, that likely means there is an underlying error so it redirects to the homepage. You can modify your bootstrap.php file and set display_errors and display_setup_errors to 1 and retest to see if it outputs an error on screen.

It looks like that is already set by default. This is what I get have from the bootstrap.php file -

    #Don't display errors
    ini_set('display_errors', '1'); // Set by installer
    ini_set('display_startup_errors', '1'); // Set by installer

Is there a file that would log any errors?

Many different ones but sometimes none; welcome to the world of debugging lol Typical logs are PHP error logs and Apache error logs but could be a number of different logs depending on where the issue lies.

Post a screenshot of your email's oauth2 config information (censoring any sensitive information).

I had already checked the PHP and Apache error logs but nothing was being added at the time I tried to submit the plug in.

Are your endpoints really the "common" ones? Those are just the defaults we ship with that you are supposed replace with your real endpoints. You may be using the "common" ones but you need to verify to ensure that. Go to the app registration in azure, go to Overview tab, click on Endpoints button at the top, and look for the OAuth2 (v2) endpoints. Then compare them to see if they differ from the "common" ones. If so, update your endpoints in osTicket and retest.

Cheers.

The url contains the secret all along. If you read it it says the app is not configured as a multi-tenant application and cannot use the common endpoints. So my above response still stands true. You need to get the real endpoints and update them in osTicket.

Cheers.

Sorry. Disregard the screenshot. I must have had set the default endpoints during my troubleshooting by mistake. I just applied the correct endpoints but get the same 'No input file specified' error.

If you've already made the change to the api/.htaccess file of adding [R,L] then that error means one of three things:

URL Rewrite module is not installed or enabled in your Apache instance. Google the correct command to check that for your specific OS.
The URL Rewrite module may be installed and enabled but URL Rewriting is not enabled for the site. See the example below of a proper <Directory> block that allows URL rewrites.
The URL is returning like your earlier (now deleted) post with some bull-crap tacked on to it. A proper redirect should look like: https://domain.tld/api/auth/oauth2?code=xxx&state=xxx&session_state=xxx

Apache Site Config Example

Note: This is obviously an example. Your config may look different - the patch will definitely be different.

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

Cheers.
