I'm trying to sign out from my vanilla (v2.1.5) forum, from another site (in the same domain) : when the user click on "sign out" on my site, he/she should be logged out from both my site and vanilla. To do this, I need to call the Vanilla signout url with the TransientKey as parameter, but I can't find it in the DB. There is a TransientKey column in gdn_session table, but it remains always empty.
Where can I find this TransientKey ? is it stored somewhere in the db ?
Another option would be to clear all cookies set by Vanilla ... it works but I'm not sure this is the correct way to do it?
Any advice would be appreciated.
