How to get user id from adapter

问题

Using Mobilefirst Platform 7.1,

I have a custom authenticator and login module. It the similar as the sample in the docs

I also have an java adapter with an endpoint that is protected with a realm that uses the authenticator and login modules.

WLServerAPI serverAPI= WLServerAPIProvider.getWLServerAPI();

@Path("/qdef")
@Produces("application/json")
@GET
@OAuthSecurity(scope="MyAuthenticatorRealm")
public Response getQdef(){
    SecurityAPI security = serverAPI.getSecurityAPI();
    /** Next line appears in below stack trace as com.ibm.jp.SubqmjrPcApiResource.getQdef(SubqmjrPcApiResource.java:92) **/
    OAuthUserIdentity identity = security.getSecurityContext().getUserIdentity();
    String username = identity.getId(); // *** identity is null ***
    String displayName = identity.getDisplayName();
    logger.info("id:"+username+", name:"+displayName);
    ... 
}

However that endpoint return 500 since an exception occurs. identity object is null. Why is this? Is this the correct way of accessing user id?

Things that I have checked:

• Authenticator seems to works fine: The first time I call the api, my browser app enters the login flow. I have checked with the debugger that the authenticator correctly holds username and password. Also I have checked that getAuthenticationData() method correctly makes a Map with such info.

• Login module seems to work fine too. It is correctly initialised and it receives correct info at login(Map<String, Object> authenticationData) method. It stores the username and password to later create an UserIdentity object in UserIdentity createIdentity(String loginModule) method. I have checked that this method contains the right data.

• The client browser app successfully received {authStatus:"required"} and then {authStatus:"completed"}. Prior to reach inside the getQdef() method.

This is just the tip of the error and stack trace (scroll right to see the file/lines):

Entire stack trace is here

The user/password I tried was admin/admin. So I have no idea were does that message comes from. I wonder what I am missing?

Any help is highly appreciated.

EDIT 2015/08/27 17:28 +0900 Is this kind of message: Authentication did not succeed for user ID KRJxLToMJb. An invalid user ID or password was specified. related to the result of securityContext.toJSON().toString()?

{"imf.application":{"environment":"common","id":"subqmgr","version":"1.0"}, "imf.sub":"::KRJxLToMJb","imf.device":{"osVersion":"","model":"","id":"","platform":null}, "imf.user":null}`

In order for adapters to have access to the User ID, your application descriptor needs contains a value for userIdentityRealms.
