Checkmk Werk 12127: Fix one site logging out the login session of another site

ID: 12127 Title: Fix one site logging out the login session of another site Component: Multisite Level: 1 Class: Bug fix Version: 2.1.0i1 Since #11499 we are tracking login sessions in each site individually. This results in one change of the authentication session handling that has not been mentioned in the previous werk before. In previous Checkmk versions it was possible to share login session between Checkmk sites of a single distributed setup. You could login into the central site and then browse to the user interface of the remote site and did not have to login into that site because your central site login session was accepted. This is not possible anymore. The result is: The login sessions of Checkmk sites are now completely independent of other sites.
