WL.Server.getActiveUser returns Null - ibm-mobilefirst

Question

I need the ability to get a users login userid/password in a java adapter. After reading lots of articles, the best way seems to be to call
WL.Server.getActiveUser from a javascript function that gets called from the java adapter. So, I added a getIdentity function to the http adapter that authenticates our app. I have verified that getActiveUser works in the authentication function that the login pages calls...
When I call the getIdentity function, getActiveUser returns null using The same authentication realm. I have set the realm in the application_descriptor file. Not sure what else I have to do. Any ideas?
function performAuthentication(username, password) {
WL.Logger.info("In performAuthentication: username = " + username + " password = " + password + "Time = " + new Date(new Date().getTime()).toLocaleString());
var invocationData = {
adapter : 'BluePages',
procedure : 'authenticate',
parameters : [username, password]
};
var invocationResult = WL.Server.invokeProcedure(invocationData);
var fullName = invocationResult.result.fullName;
if (invocationResult.result.success == false) {
return {
authRequired: true,
loginPassed: false
};
}
else {
userIdentity = {
userId: username,
credentials: password,
displayName: username,
attributes: {
foo: "bar"
}
};
WL.Server.setActiveUser("AuthRealm", null);
WL.Server.setActiveUser("AuthRealm", userIdentity);
var activeUser = WL.Server.getActiveUser("AuthRealm");
WL.Logger.info("activeUser = " + activeUser);
if(activeUser && activeUser.userId == username){
WL.Logger.info("Active userId = " + activeUser.userId + " password = " + activeUser.credentials);
WL.Logger.info("User has been logged in!");
return {
loginPassed: true,
authRequired: false,
fullName: fullName,
result: invocationResult.result
};
}
else {
WL.Logger.info("Else Clause...");
if(activeUser != null)
WL.Server.setActiveUser("AuthRealm", null);
WL.Server.setActiveUser("AuthRealm", userIdentity);
}
return {
authRequired: false,
loginPassed: true,
fullName: fullName
};
}
}
function getIdentity() {
WL.Logger.info("AuthAdapter: In getIdentity: Time = " + new Date(new Date().getTime()).toLocaleString());
WL.Logger.info("AuthAdapter: userIdentity = " + userIdentity);
var activeUser = WL.Server.getActiveUser("AuthRealm");
WL.Logger.info("AuthAdapter: getIdentity: getActiveUser returned = " + activeUser);
if (activeUser) {
WL.Logger.info("AuthAdapter: getIdentity userId = " + activeUser.userId);
return {
userId: activeUser.userId,
credentials: activeUser.credentials,
};
}
}

Answer 1

There could be 2 reasons to get null when using WL.Server.getActiveUser:
1)If no realm is defined on the adapter, the method returns null (active user is unknown)
2)If a realm is defined on the adapter:
If there is no strong identity associated with the user (the user was authenticated in this session or in a previous session), the method returns null.
In your case you said the realm is exist so I suggest to try #2
