Web Interface vs StoreFront logon process

The user logon workflow (logon process) in StoreFront is different to Web Interface. The detailed description of the logon process is shown in Table 1.

Figure 1

Step	Web Interface	StoreFront
1	User enters username and password.  This is sent to the Web Interface server.	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	Web Interface forwards the user credentials as part of a XML  query to XenApp or XenDesktop sequentially. In this case, the  credentials are sent to the XenDesktop Controller which is the sole resource configured.	StoreFront forwards the user credentials as par t 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 resource  available for the user from the XenDesktop site.
8	Web Interface displays the available resources.	StoreFront sends the list of available resources  including the existing subscriptions to the Citrix  Receiver installed locally or displays them in  Receiver for Web.
9	Now the user can start a resource.
