You can use a token associated with your user for authentication.
If the server is defined with SSO, this will be the only way for this plugin to authenticate.
To use it, have a token (access key) issued to your user.
In Jenkins, create new Jenkins credentials based on the token you received: use the value of ClientIdKey in the Username and the value of ClientSecretKey key in the password.
Then use the new Jenkins credentials with this checkbox switched on.
