To manage users separated by site in Sitefinity, it is necessary to set up a Membership Provider for each site. Each website must be configured with the corresponding Membership Provider using this setting. The setting maintenance displays the membership providers that exist in Sitefinity.
After creating the provider, you must restart the application by modifying the Sitefinity web.config file or following the steps in the Sitefinity Documentation (https://www.progress.com/documentation/sitefinity-cms/administration-application-restart).
After the application restarts, you will see that the new provider is active.
Beginning with version 7.1 standard Sitefinity Site-Specific Users will be utilized to manage Membership Provider. For more information click here.
Sitefinity limits users’ concurrent sessions so that they are not allowed to be logged in simultaneously from different browsers and machines. When trying to login to the website if there is another valid session open for a given user there will be an additional question to confirm to log out the previous session. This setting allows you to automatically logout users out from other HTTP clients upon login.
