Facing issues while integrating Mobilefirst CLI 7.1 with ldap - authentication

Question

I am using mobile first CLI 7.1 and trying to integrate with the LDAP.
I am following this document to implement. I am getting 401 error (Failed to load resource: the server responded with a status of 401 (Unauthorized)) when loading the application for first time in the browser. I am getting 500 error(POST http://localhost:10080/Project/apps/services/j_security_check 500 (Internal Server Error)) when I try to logging in. I have uncommented wl.client.connect and gone through the following conversations at stackoverflow. Link1, link2 and link3
Server Logs
[ERROR ] SESN0008E: A user authenticated as anonymous has attempted to access a session owned by user:BasicRegistry/admin.
[ERROR ] SESN0008E: A user authenticated as anonymous has attempted to access a session owned by user:BasicRegistry/admin.
[ERROR ] SESN0008E: A user authenticated as anonymous has attempted to access a session owned by user:BasicRegistry/admin.
[ERROR ] SESN0008E: A user authenticated as anonymous has attempted to access a session owned by user:BasicRegistry/admin.
What is my scenario?
User is initially taken to login page and later when he clicks on login I will collect the details and automatically set to j_secutity_form when it throws challenge and submit. I am getting 401 when I open the application and getting 500 when I click on login. which calls
var reqURL = '/j_security_check';
var options = {};
options.parameters = {
j_username : loginData.email,
j_password : loginData.password
};
options.headers = {};
ldapRealmChallengeHandler.submitLoginForm(reqURL, options,ldapRealmChallengeHandler.submitLoginFormCallback);
I have following questions:
1) Is the documentation that I am following is complete or it needs some additions thing that need to be done ?
2) What is the cause for getting blocked with the above errors
And here is my code:
var ldapRealmChallengeHandler = WL.Client.createChallengeHandler("LDAPRealm");
ldapRealmChallengeHandler.isCustomResponse = function(response) {
if (!response || response.responseText === null) {
return false;
}
var indicatorIdx = response.responseText.search('j_security_check');
if (indicatorIdx >= 0){
return true;
}
return false;
};
ldapRealmChallengeHandler.handleChallenge = function(response){
};
ldapRealmChallengeHandler.submitLoginFormCallback = function(response) {
var isLoginFormResponse = ldapRealmChallengeHandler.isCustomResponse(response);
if (isLoginFormResponse){
ldapRealmChallengeHandler.handleChallenge(response);
}
else {
ldapRealmChallengeHandler.submitSuccess();
}
};
logout = function(){
WL.Client.logout('LDAPRealm',{});
}

I think this might be related to session independence mode which is turned ON by default as of MFP 7.1. I think this might explain why you are getting the SESN0008E error. Here is a link to an article that explains how to disable session independence.
There is more information on the SESN0008E error here.
Please let me know how you get on.
