Enable SSL support on VDA

1. Obtain an SSL Server certificate for all your VDAs. A certificate issue by a trusted third-party root CA is recommended, however a self-signed certificate can also be used.
2. Install the certificate in the Computer certificate store (not the user store). If the local certificate store on the VDA is used to generate a CSR, ensure that the private key is marked exportable. If a pkcs12 is used to install certificates, ensure that keys are marked exportable during pkcs12 import.
   

   Once the certificate is installed, it must indicate that certificate private key is available

3. Note down the certificate thumbprint, as it will be used to associate the certificate with the VDA
4. Once the certificate is installed, navigate to 'Manage private keys' and allow full control and read permissions for ‘PorticaService’.
   This service can be added by searching for 'NT SERVICEPorticaService' under the computer directory (not under the domain)
   
   
5. Open registry editor on Windows and edit the following registry:
   HKLMSystemCurrentControlSetControlTerminalServerWdsicawd
   At this registry, you need to complete two steps:
   1. Edit the binary value of 'SSLThumbprint' and manually type the thumbprint saved from step 3
   2. Change the DWORD value of SSLEnabled to 1 (from 0)

8. Finally, provide a name for the policy and check the 'Enable policy' box

   Asnp citrix.*
   Get-BrokerAccessPolicyRule –DesktopGroupName ‘GROUPNAME’ | Set-BrokerAccessPolicyRule –HdxSslEnabled $true
