Did anyone do or runs a D11 multisite? I want to use a domain domainname.com as homepage and have different categories which will have subdomains sub1.domainname.com, sub2.domainname.com, etc. - my plan is to set up a multisite, all the sites should or can have their own database and want to share userlogin over all sites so that users login in one time and are logged in on all sites - is this possible?
