saml-20-single-sign-on

Used this with an idp I created based on simplesamlphp and it works great.

SAML is hard. Most of the people here saying it doesn't work probably don't know how to do SAML properly. I tested this plugin on 4.7 in multisite and standalone mode and it works great! There are some neat debugging strategies that simpleSAMLphp provides. Look into enabling the simpleSAMLphp admin dashboard for assistance with troubleshooting.

The plugin does authentic but does not let the user into the Admin area - HTTP Error 302. I'm connecting Wordpress (SdP) to Salesfroce (IdP). Salesforce works and I can see the user has been logged in. But Wordpress fails after authentication. What is annoying is there isn't any suitable documentation or anyone to contact for support.

Relies on Apache/PHP and PATH_INFO.

I tried installing this on a IIS box using latest WordPress (4.3.1) and found that the plugin seemed to remember settings after plugin was deleted and reinstalled. I was unable to get this plugin to work, it seems to use .htaccess files rather than the web.config I needed. Although the keys were saved to the right folder, the metadata.php/1 file returned an error and the .cer file was returning 404 through the browser although a text file in the same folder rendered ok. It's a shame as this seems to be the only SAML plugin that isn't reliant on a third party app / sign up. - In my case my client had their own ID provider.

This plugin works fine on all our sites. We use simple SAML php as IdP. Installation is quite simple and we've seen no errors up to this point. Didn't test it with multisite.
