No "domain cookie" in IPS4?

[RObiN-HoOD]

I can't find in ACP "domain cookie" setting. Is there one?

Nope. It sends without, which works better.

If you have a custom SSO setup which requires sending something different, it can be done by adding to constants.php:

define( 'COOKIE_DOMAIN', 'example.com' );
