Please note you will need to pass uid (in the plugin) instead of wp_userid as the documentation indicates. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[simpleSAMLphp Authentication] Plugin doesn't log me in to WP](https://wordpress.org/support/topic/plugin-doesnt-log-me-in-to-wp/) * [colemab](https://wordpress.org/support/users/colemab/) * (@colemab) * [13 years, 6 months ago](https://wordpress.org/support/topic/plugin-doesnt-log-me-in-to-wp/#post-3442320) * I am new to wordpress plug-ins and so I am not sure *why* this works but the code above works for me. Since you were having the same problem, I thought I would share what I found. * Maybe you can take that line out and let us know if it works for you?
