DDC queries Citrix License server to verify that the end user has a valid ticket.ġ1. Virtual Delivery Agent (VDA) verifies the license file with the DDC and exchanges the ticket for user credentials with the DDC.ġ0. Note: In the case of Single Sign-on or Smartcard authentication, instead of the ticket, Launch Ref is exchanged with the DDC.ĩ. Citrix Receiver establishes an ICA connection to the specific virtual machine that the DDC allocated for this session and passes the Ticket embedded in the ICA file. Web Interface/StoreFront creates and sends an ICA file to the Citrix Receiver pointing to the virtual machine that hypervisor identified.Ĩ. DDC identifies to Web Interface/StoreFront the virtual machine it assigned for this particular session.ħ. Using the Delivery Group information obtained from the database for the resource the user requested, DDC queries the hypervisor about the status of resources within that group.Ħ. This request is sent to the Delivery controller through the storefront. User clicks on one of the resource icons to start a desktop or application session. The resources defined by the Delivery Groups are sent to the WI or SF server and presented to the user (enumeration).ĥ. DDC then queries the site SQL database for the end user’s assigned Delivery Groups (SQL named instance uses default ports 14). SF then passes the validation over to the DDC to begin resource enumeration (Step 4).Ģ.b For Web Interface, the username and password is passed to the Desktop Delivery Controller (DDC).ģ. The DDC then queries a Domain Controller with the end user’s credentials to verify user authorization.Ĥ. a For StoreFront, the credentials are verified directly to a Domain Controller (Similar to Step 3). The user device submits credentials to the Citrix web site hosted on either a Web Interface (WI) or StoreFront(SF) web server.Ģ.
