@nebulon Well, both apps do support LDAP in the Cloudron package, but I do need users to sign up within one of the apps. If those credentials could somehow make their way up to my Cloudron, then the LDAP integration would take care of the second app. Does that make any sense?
To be more explicit, one is a Wordpress site with an ecommerce plugin where users create an account as they make a purchase, and the other a Nextcloud instance where they need to sign in to collect their purchase.
So they should be able to sign in with the same credentials, and I can't quite ask them to also sign up for a Cloudron account to LDAP them into both apps, as it should not be confusing or complex for them.
In theory, it should be easy to use either Wordpress or Nextcloud as OAuth source for the other, but in practice I am struggling (and can't afford expensive Wordpress plugins that promise to do it better, as this is a tiny operation), hence looking for some type of workaround...
