@Friendica Day A bit late, and not really ready, but jappixmini has a new feature: The administrator can now specify the address of a eJabberd server and Bosh host he operates.
He can configure his eJabberd so that it authenticates against Friendica (using a so-called extauth script which can be downloaded from the jappixmini addon admin settings).
This means that the user effectively does not have to configure anything - he gets a Jabber account automatically, with the same credentials as his Friendica account.

Brave server admins can test it already It's not in the official repository yet, but at friendica-addons on Github

Currently, if the admin activates this functionality, users can not override this, but I want to change this later.
