While executing the workflow to update or adding a powerShell host using the powerShell plugin throws error   'KDC Server could not be found' . 

A sample detailed error looks like: 

No valid credentials provided (Mechanism level: No valid
credentials provided (Mechanism level: Server not found in Kerberos
database (7)))

Environment

Cause

This error might be caused by several misconfigurations.

The PowerShell host is not part of a domain.
The host to realm mapping is not correct.
The Service Principal Name of the PowerShell host is not built correctly.

Note: Kerberos authentication does not work when the destination is an IP address.
