Update SSO

Update SSO issue with other applications like Drupal using the same Azure AD B2C tenants.

Edit Profile

also added an edit/update profile information into Azure AD B2C and reflect the same changes in Moodle. For edit/update profile(Azure AD B2C profile) to work, one needs to do the following
Add the following code to the theme's profile.php and if you are not using the customize page for profile, then add it to the layout page which the profile page will use.

<?php
    $id_token = "";
    if(!empty($_COOKIE['id_token'])) {
        $id_token = $_COOKIE['id_token'];
        $idtoken = explode("=",$id_token);
    }

    $editcheck = get_user_preferences('auth_azureb2c_edit');
    if($editcheck == 0 || $editcheck == 2 ) {
        if($editcheck == 0) {
            set_user_preference('auth_azureb2c_edit', 2);
            header("Refresh:0");
        }
        if($editcheck == 2) {
            $userid = optional_param('id', null, PARAM_INT);
            if(!empty($idtoken[1]) && ($idtoken[0] =="#id_token")) {
                updateuserazureb2c($userid, $idtoken[1]);
                $_COOKIE['id_token'] = null;
                set_user_preference('auth_azureb2c_edit', 1);
            }
        }
    }
?>

<?php
    $url = get_config('auth_azureb2c', 'editprofileendpoint')."&client_id=". get_config('auth_azureb2c', 'clientid')."&
    nonce=defaultNonce&redirect_uri=". $CFG->wwwroot."/auth/azureb2c/&scope=openid&response_type=id_token"; 
?>
<a href="">&lt;?php echo get_string('editmyprofile'); ?&gt;</a>

Add the folloing function to theme's lib.php

function updateuserazureb2c($userid, $id_token) {
    global $CFG, $OUTPUT, $USER, $PAGE, $DB;
    require_once("{$CFG->dirroot}/auth/azureb2c/classes/loginflow/base.php");
    $idtoken = \auth_azureb2c\jwt::instance_from_encoded($id_token);
    $username = $idtoken->claim('oid');
    if (!empty($username)) {         
            $firstname = $idtoken->claim('given_name');
            $lastname = $idtoken->claim('family_name');
            $country = $idtoken->claim('country');
            $countryval = "";
            if (!empty($country)) {
                    $countries = get_string_manager()->get_list_of_countries();
                    foreach ($countries as  $countrykey => $countryvalue) {
                        $countryb2c = $country;
                        $countrymoodle = $countryvalue;
                        if($countrymoodle == $countryb2c)
                            $countryval = $countrykey;
                    }
            }
        $gender = $idtoken->claim('extension_WP_Gender');

        $userupdate = new \stdClass;
        $userupdate->id = $userid;
        if (!empty($firstname))
            $userupdate->firstname = $firstname;
        if (!empty($lastname))
            $userupdate->lastname = $lastname;
        if (!empty($countryval))
            $userupdate->country = $countryval;
        $DB->update_record('user', $userupdate);

        $USER->firstname = $firstname;
        $USER->lastname = $lastname;
        $USER->country = $countryval;
        return true;
    }
}
