There are several new SimpleSAMLPHP related tests added to action_admin_notices() via commit 89a3d5e that run also when the config specifies to use the 'internal' backend. That is inefficient and leads to incorrect warnings in the logs.

The easy workaround is to put

• lines 694-695
• lines 723-808

in an else clause to the if statement in line 699.

I will open a PR doing the above.
