Event ID 7 appears in the Windows Event Viewer stating that, "ICA Connection request denied because the current user (user name) is not the owner of the session (session ID)"

• This behavior is traditionally not related to the configuration of the Citrix Environment, but is usually related to the SIDs of the User Accounts themselves.
• Citrix recommends reaching out to any third-party Credential providers if available to assist.
  • Otherwise, Citrix recommends that the User SIDs be investigated and checked to see if there are any duplicate SIDs associated to the user objects in the Active Directory Domain.

Problem Cause

• User SID Mismatch : When there is a SID mismatch while launching applications
• Un-brokered access :  When trying launch a session or application using a custom ICA file fails
• Ticket mismatch
• Connection Error

• ​The issue happens when users are attempting to launch multiple applications (from same client and user) before the first application launch is complete.
• 1st application launch is required for session sharing. If users are clicking on a second application before the first one is launched, the second launch is getting denied.
  • A warning message is posted to the event log for informational purposes.
