I have trial access to the SAP Web IDE and SAP Gateway (ES4). I can logon (with my SCN client certificate) to the Web IDE at: webide-s00********trial.dispatcher.hanatrial.ondemand.com however, when I want to create a new project from template I get prompted (basic auth) for a login. The thing is my username/password is not accepted. I am 100% sure of the username/password as I can use it to access the web gui at sapes4.sapdevcenter.com/sap/bc/gui/sap/its/webgui.
If I cancel the login I get:
Unable to access the selected system. Check your credentials and try again. If the problem persists, check if the OData service is available and contact your backend system administrator.
Interestingly my user does not get locked even if I try to login 20 times so it seems it's not authenticating with the ES4 system at all.
