Security provider not using the 'cookie options'

[franse]

I confirm the bug.

When you setup your security provider use the mymaindomain.com in the cookie settings, this way the user will be logged in on the subdomain as well.

That, also don’t work.
The module JSON is saved correctly, but having problems on php 8.1.21 and 7.0.3
