Can confirm this happening for our instance (31.0.7) as well. The 7.0.0 Update made the App non-functional with the same symptoms.

The provided fix works and we applied it manually to restore functionality. Thanks a lot for figuring it out!

I too can confirm that user_saml is currently broken. I've also applied your patch and it works again. Thanks.

The same problem occurs with 7.1.0; same fix is working for me.

Nothing related in this regard has changed within 7.0.0 or 7.1.0 on our side. Auto-tests also continue to work correctly as well as any other configuration I was looking at.

# diff vendor/onelogin/php-saml/src/Saml2/Utils.php.orig vendor/onelogin/php-saml/src/Saml2/Utils.php

This is related to the library we are using, https://github.com/SAML-Toolkits/php-saml/

Could it be related to SAML-Toolkits/php-saml#629 ?

You have to have something in your setup/configuration that leads to this situation (not saying it is your fault, I am not making any conclusions at this time).

[pelzvieh]

It appears that this is the same problem indeed. It seems that any installation is affected, where Nextcloud is on a path on a reverse proxy: https://somehost/nextcloud/ in my log.
Surprisingly, the validation error is not related to that path, but the received request is built to a string that duplicates the relative path within the nextcloud installation (apps/user_saml/saml/index.php/apps/user_saml/saml in my log).
Therefore definitely a coding error.

Can confirm this still happening as before. The upgrade to 7.1 happened automatically and effectively deleted the fix described above which we applied manually. How can we accelerate the fix? Is this something that has to be handled upstream as this is some external module?
Its troubling that this app currently does not work with path-based setups.

[blizzz]

Yes, it is an upstream issue, as confirmed above.
