I installed Debian Jessie without a desktop environment and installed i3wm afterwards. If I start an application which requires administrative privileges inside i3wm other than by running the command in a terminal (e.g. through dmenu) a GUI password prompt pops up saying:
APPLICATION needs administrative privileges. Please enter your password.
However, no matter what I put in there and no matter whether I chose
Save for this session or
Save in the keyring it always displays
Incorrect password ... try again.
