I am trying to single sign on to OCS (2007) and am trying this code: //Formulate the form with hidden fields that will be posted to Communicator's logon page formInput = "<form action='" + authenticationUrl + "' method='post' name='myform' id='myform'>"; formInput += "<input type='hidden' name='uri' value='" + accountUri + "'/>"; formInput += "<input type='hidden' name='user' value='" + username + "'/>"; formInput += "<input type='hidden' name='pw' value='" + password + "'/>"; formInput += "<input type='hidden' name='signinas' value='" + signOnStatus + "'/>"; formInput += "<input type='hidden' name='language' value='" + language + "'/></form>"; Response.Write(formInput); This is returning error id code 4. But I supply the correct credentials to this it seems? Any ideas of how to single sign on to OCS? Thanks in advance!Rob McCabe
