[rules-users] direct access to guvnor servlet without login

Hello everyone! I saw several threads related to this or a similar question: - how to directly access the Guvnor securityService servlet without the login window. In the single sign-on scenario it is desirable to pass user credentials directly. What is the URL to pass the credentials? I provide below the example, but this example does not work /drools-guvnor/org.drools.guvnor.Guvnor/securityService?username=[]&password=[] GWT and SEAM frameworks are good in hiding the URL. Did anyone do this? What is the URL? Thank you for sharing! Jeff
