Environment:
- Citrix Storefront 1912
- Store enabled for Domain Pass Through
- Cloud Connectors configured as Delivery Controllers on HTTPS/443
- Citrix Cloud Connectors
Issue:
When we were browsing to the Storefront URL it would do Domain Pass Thru, it logs in as the user but no apps or desktops available.
In Event Viewer it has 3 errors:
- Cloud Connector 1 is not available
“The Citrix XML Service object was not found: 404 Not Found. This message was reported from the XML Service at address https://<cloud_connector_1>/scripts/CtxIntegrated/wpnbr.dll. The specified Citrix XML Service could not be contacted and has been temporarily removed from the list of active services.”
2. Cloud Connector 2 is not available
“The Citrix XML Service object was not found: 404 Not Found. This message was reported from the XML Service at address https://<cloud_connector_2>/scripts/CtxIntegrated/wpnbr.dll. The specified Citrix XML Service could not be contacted and has been temporarily removed from the list of active services.”
3. All the Citrix XML Services configured for farm failed to respond to this XML Service transaction.
“All the Citrix XML Services configured for farm <name> failed to respond to this XML Service transaction.”
After around 10secs in Event Viewer
- Cloud Connector 1 is available
“The Citrix XML Service at address <cloud_conenctor_1>:443 has passed the background health check and has been restored to the list of active services.”
2. Cloud Connector 2 is available
“The Citrix XML Service at address <cloud_conenctor_2>:443 has passed the background health check and has been restored to the list of active services.”
If we refreshed the Storefront URL or browse again the above process repeats.
If we enabled the Store to do Username/Password auth we can log in fine and apps are there.
Resolution:
Within Storefront,
- Select the Store experiencing the issue
- Select Configure Store Settings
- Select Kerberos Delegation
- Select ‘Disable Kerberos Delegation’
As soon as Kerberos Delegation was disabled, Storefront Domain Pass Through continued to work, all applications were available and no errors in the Storefronts Event Viewer.
