Shouldn't this also be blocked then in the actual login controller? Otherwise it would just be the form that is hidden.

Would still be good to have a way to manually enable the login as mentioned in #3 to have a way to get back to it if something
went wrong on the Nextcloud side.

Thanks for the review, julius :)

Not sure how important that is since it should fail in that case due to the csrf check?
@LukasReschke what is your take on this? :)

Already implemented. See https://github.com/nextcloud/all-in-one/pull/94/files#diff-e91b468a29aee3ff92547f02d1032086caca43138d1f9c5f693dea700f3e6058R17-R18 :)
