After being applied to the 8.x branch, it should be considered for backport to the 7.x branch. Note: This tag should generally remain even after the backport has been written, approved, and committed.
The last steps the code takes before redirecting users is checking whether maintenance mode is enabled, the logged in user has the permission to access the site in maintenance mode, and the redirect URL has been set.
The code should instead:
If the redirect URL has not been set, exit immediately
If maintenance mode is enabled and the logged in user has the access site in maintenance mode permission, exit immediately
Then, the code should verify the other conditions are met.
When the Enable URL redirect checkbox is selected, the Redirect URL text field is made visible, but it should also be made required, or that field could be used to submit an empty value.
The user group API endpoint has a default limit of 100 groups by request. This means that if a user has >100 user groups, we only get the first 100 and none of the rest.
We need to handle pagination to fetch the rest.
Steps to reproduce
It's not practical to test with 100 user groups... these are steps to simulate the issue with fewer groups.
