Authentication

Hi Hiren Bhut 

     I got the same error and by making few configuration changes you can get rid of this problem. go the authsources.php page in your simplesaml/config/ directory and make a change as per you want

In authsource.php

        'admin:Admin123$' => array(
            'uid' => array('admin'),
            'eduPersonAffiliation' => array('member', 'admin'),
        ),
    ),

that bold text should be mapped in saml configuration 

SAML username mapping:  eduPersonAffiliation

in instead of uid=username you have to change eduPersonAffiliation and  then check whether you receive it again
