"handleApacheAuth()" can throw a LoginException when trying to authenticate as a disabled user. This needs to be explicitly handled to redirect to an error page, as otherwise the login page will try to be loaded which, in turn, will try to authenticate again and cause an endless loop.

I think there should be a fitting Exception or interface in the OCP space, no?

#549 might be fixed by this, although I am not sure if the problem can happen too when using SAML 2.0 or only when authenticating via environment variable (this pull request only fixes it when authenticating via environment variable).
handleApacheAuth()can throw aLoginExceptionwhen trying to authenticate as a disabled user (and it has done it since Nextcloud 23.0.0, 22.2.1, 21.0.6 and 20.0.14). This needs to be explicitly handled to redirect to an error page, as otherwise the login page will try to be loaded which, in turn, will try to authenticate again and cause an endless loop.How to test
Result with this pull request
An error page with Account disabled is shown
Result without this pull request
Infinite loop of redirections
