Scenario: A Citrix Architect has met with a team of Workspacelab members for a design discussion. They have captured the following requirements for the Citrix ADC design project:

• The Citrix Gateway virtual server is integrated with the Citrix Virtual Apps and Desktops environment.

• The authentication must be deployed for the users from the workspacelab.com and vendorlab.com domains.

• The workspacelab users connecting from the internal (workspacelab) network should be authenticated using LDAP.

• The workspacelab users connecting from the external network should be authenticated using LDAP and RADIUS

• The vendorlab users should be authenticated using Active Directory Federation Service.

• The user credentials must NOT be shared between workspacelab and vendor) ab.

• Single Sign-on must be performed between F and Citrix Gateway.

• A domain drop down list must be provided if the user connects to the Citrix Gateway virtual server externally.

• The domain of the user connecting externally must be identified using the domain selected from the domain drop down.

At which bind point should the architect bind the domain drop-down schema policy?
