Hi all,
Im looking at implementing a solution in wordpress where discourse becomes the SSO provider.
I already have 1000+ users on discourse and want to allow users to have accounts on the wordpress site.
Does anyone know whether this is possible today using exiting plugins?
thanks
SSO provider is built in, search site settings. Not sure it’s very well documented at the moment but @sam added it a while ago.
thanks Jeff,
I’ve configured discourse as the SSO provider, but unsure whether a plugin exists for Wordpress to redirect to logins to discourse.
How does one re-direct the Wordpress logins to discourse.
I’ve installed WP-OAUTH in the hope that one can copy an existing provider.php file and modify to get it to work with Discourse. Copied the gitbhub one, settings are below if you any one trying something similar. Not working yet.

?>Is this working ? I can’t find any post about integrating discourse as a sso provider for wordpress
Looking for something similar. Can’t find much via search. I’m thinking this should probably be an official option in wp-discourse (using Discourse as the authority rather than WordPress).
Any update on this one. WP struggles to have a proper user profile. Discourse seems to be the obvious choice when using with WP.
Using Discourse as an SSO provider is documented here:
That howto also links to a PHP script by @paxmanchris that implements Discourse as SSO provider:
أُضيء على هذا الأمر بعد مرور ما يقرب من 4 سنوات، لأرى ما إذا كان هناك أي تحديثات بالصدفة.
نحن نبني موقع ووردبريس حول منصة ديسكوس، ونرغب في فرض التسجيل للبقاء على ديسكوس (مع كل المزايا التي يوفرها)، واستخدام ووردبريس كفرصة لتسجيل الدخول الموحد (SSO).
هل لدى أي شخص خبرة في القيام بذلك والتحديات التي واجهها ربما؟
يحتوي إضافة WordPress لدينا على خيار يسمح للمستخدمين بتسجيل الدخول إلى WordPress من خلال Discourse. تتيح هذه الإضافة لـ Discourse العمل بطريقة مشابهة لخيارات تسجيل الدخول عبر الشبكات الاجتماعية الأخرى، مثل تسجيل الدخول إلى WordPress عبر Facebook. توجد إعدادات التكوين هذه في علامة تبويب خيارات عميل SSS الخاصة بالإضافة.
شكرًا جزيلاً لك على هذا الإضافة الرائعة.
