UserProvider is null. Why?

Hi,

I just deployed my application to my sapdev account, using the SAP ID Service as a Userprovider.

Then I want to get the currently logged-in user with the following code:

UserProvider userProvider = UserManagementAccessor.getUserProvider();

user = userProvider.getUser(request.getUserPrincipal().getName());

It fails, because the userProvider is null. I remember using this code some time ago and it worked, so I dont understand why it fails? I checked the included libraries, and they are okay.

Does this not work because I am using a sapdev account and need a full-account? Or do i need to do some configuration in the account itself?

Edit: I also added the necessary <login-config> in the web.xml, i tried with FORM and SAML2 which seem to be the same when used without <form-login-config>?

I also added a security role and added the role to my user using the cloudcockpit.

Regards,

Kevin
