Redmine

Hello,

i try to contribute to a plugin which allows the login via http header variables. therefore i would like to give the possibility to change the login and logout links to some external.

I would like a behavior where all restricted areas are redirecting to the custom login url and the Logout-Link in the top right points me to the custom logout url. Also i would like to keep the default login so that an admin could login even when the external system is unavailable by manually going to `/login`.

Is this even possible? how would i achieve that?

Thanks in advance
