After upgrading Aria Automation Orchestrator to 8.18.1 it does not retrieve current authentication provider configuration that was configured previously. As the Control Center is removed in this version the only way to check this is via the command line using "vracli vro authentication"
It will return "No authentication provider configured."
If the authentication provider was set in the Control Center previously then the command will not return any result. This is due to the Control Centre being removed in 8.18.1. The Control Center and the command "vracli vro authentication" use different mechanisms so the command will not show what was configured in the Control Center.
This is a known issue.
The workaround is to unregister the re-register the authentication provider on the command line of the node using the following method
Previous authentication provider details can be found in the following files on the Aria Automation Orchestrator node:
/data/vco/usr/lib/vco/app-server/conf/vmo.properties
/data/vco/usr/lib/vco/app-server/conf/csp.properties
/data/vco/usr/lib/vco/app-server/conf/sso.properties
