 1. User enters username and password. This is sent to the
StoreFront server. 2. The authentication service of StoreFront fetches the user
credentials and validates them with a domain controller. StoreFront servers
must reside either within the Active Directory domain containing the user
accounts or within a domain that has a trust relationship with the user
accounts domain. All the StoreFront servers in a group must reside within the
same domain. 3. StoreFront checks the data store for existing user
subscriptions and stores them in memory. 4. StoreFront forwards the user credentials as part of a XML
query to the backend systems, such as XenApp, XenDesktop, App Controller or
VDI-in-a-Box sequentially. In this case the credentials are sent to the
XenDesktop Controller which is the sole resource configured. 5. The XenDesktop Controller validates the user credentials
with a domain controller. 6. After a successful validation the XenDesktop Controller
checks which resources have been published to this user within its database. 7. The XenDesktop Controller sends an XML response to Web
Interface / StoreFront which contains all resources available for the user from
the XenDesktop site. 8. StoreFront sends the list of available resources
including the existing subscriptions to the Citrix Receiver installed locally
or displays them in Receiver for Web.
