SSOCircle保持重定向到Consent页面SAML2.0

Question

I am using SSOCircle to test out my SAML implementation with Codeigniter. The current steps are:

1. Access website.com
2. Redirected to SSOCircle Consent Page
3. Verify identity
4. Pass user data back to website.com

However, after step 3, it goes to step 4 and back to step 3 immediately.

This is my code:

public function index()
    {
        $data['languages']= get_all_languages();
        $sp_auth = 'default-sp';
        try {
            $auth = new SimpleSAML_Auth_Simple($sp_auth);
            $auth->requireAuth(array(
            'ReturnTo' => $this->data['controller'],
            'KeepPost' => FALSE,
            ));
            $attributes = $auth->getAttributes();
            var_dump($attributes);
        } catch (Error $e) {
            print_r($e);
        }
    }

I have considered that my redirect may be the reason it keeps calling the consent page. However when added another url for it to access with this function

public function auth(){
        $attributes = $auth->getAttributes();
        var_dump($attributes);
}

I get this error:

SimpleSAML_Error_Error: UNHANDLEDEXCEPTION

Backtrace:
1 www/_include.php:45 (SimpleSAML_exception_handler)
0 [builtin] (N/A)
Caused by: SimpleSAML_Error_Exception: No authentication source with id 'Login/Auth' found.

1 modules/saml/www/sp/saml2-acs.php:12 (require)

I'm hoping someone can take a look at this and help me with it. Thank you.

UPDATE:

I recently noticed that SSOCircle actually returns back to my login page. However, it immediately redirects it back to the SSOCircle page. Not sure if this helps

NULL Redirect You were redirected to: https://idp.ssocircle.com:443/sso/SSORedirect/metaAlias/publicidp?SAMLRequest=vVPBjtowEP2VyPfghCQqWIDELqoWabeLCO1hLytjD4ulxHY9k6X8fZ2kVbc9cOzJ0vO8N%2B%2FN2AuUbePFuqOz3cP3DpCSH21jUQwXS9YFK5xEg8LKFlCQEvX66VFMJ5nwwZFTrmEfKLcZEhECGWdZst0s2WtWgNafINe5UlrqY1lJmE1BlvOimkN10mVWZZDn85wl3yBgZC5ZFIp0xA62FklailCWz9KsSPP8kM1EVYqqeGHJJqYxVtLAOhN5FJwb7SeITpmgGpgo14qyLHhEeF0%2F70GbAIp4CyTXjZHIfXdsjIoslqx%2Fu793FrsWQg3h3Sj4un%2F8o6%2FhfRJdBe0UpjgWYN%2BH7x%2FuniCoLly59D6KDs44nU3Qr14GunI0rW%2BgnyO%2FXC68dbqLJv3Z8wHD8ZymUuGAajjJrqEUo7vdr23cGauNfbu9iONYhOLhcNilu%2Bf6wFaLXlsMgw2r%2FxSnn7OWJP9Js%2BAfvSzGR%2Folpthudi62uiafXWgl3Q7ZI0anp6FUUJAWDViKi2wad7kPIAmWjEIHjK%2FGln9%2FhdVP&RelayState=https%3A%2F%2Fwww.website.com%2Fapp

UPDATE2 : I just checked the logs and I have received this warning

Mar 12 23:26:26 simplesamlphp WARNING [da20d4a7a3] Could not load state specified by InResponseTo: NOSTATE Processing response as unsolicited.

I was told that this is because of lost state information. However I have checked my cookie names and they match up. What else have I missed?
