When namespace_in_path is enabled and auth_redirect_uri is manually updated to non-projects url, auth flow fails
Summary
When namespace_in_path
is enabled and auth_redirect_uri
is manually updated to a non-projects URL, the authentication flow fails. The user gets redirected to GitLab and back to Pages. However, Pages then issues a redirect back to itself, adding a '/' at the end. This results in a situation of TOO_MANY_REDIRECTS, where every redirect adds a new '/' to the end of the request.
Build version: v16.10.0
Steps to reproduce
Configuration is given here: #434372 (comment 1834860095)
Example Project
What is the current bug behavior?
The user gets redirected to GitLab and back to Pages. However, Pages then issues a redirect back to itself, adding a '/' at the end. This results in a situation of TOO_MANY_REDIRECTS, where every redirect adds a new '/' to the end of the request.
What is the expected correct behavior?
The authentication flow should complete, allowing the user to access the pages after entering their credentials.
