<p>Per now you need to go to <code>/feide_login</code> to log in, we should add a setting to:</p>
<p>* Include this link on <code>/user/login</code><br>
* Optionally hide normal login form</p>
<p>Example code: <a href="https://git.drupalcode.org/project/simplesamlphp_auth/-/blob/8.x-3.x/simplesamlphp_auth.module?ref_type=heads#L173">https://git.drupalcode.org/project/simplesamlphp_auth/-/blob/8.x-3.x/simplesamlphp_auth.module?ref_type=heads#L173</a> </p>
