Checking / changing a password on Safeguard returns "The service account credential type is not valid for this action. (60152)"
When selecting an account and trying to check/ change password, or attempting discovery Safeguard returns the error "The service account credential type is not valid for this action. (60152)"
This means that the Asset does not have a Connection Account configured (most likely set to "None" on the Asset 'Connection' tab) so Safeguard is unable to check/change the password, perform discovery or update an dependent asset.
Edit the Asset "Connection" tab to add a valid service account.
