Comment 5 for bug 1271341

For the GUI, we agreed on the following steps:

0) GUI team will change GUI login text to ask users to look in the jenv
files for admin secrets.

1) GUI team will change Juju Core to add JUJU_ENV_NAME environment
variable for charms, providing the human readable name of the environment.

2) GUI team will change charm to include the environment name in the
configuration file sent to the GUI, if it exists.

3) GUI team will change GUI login text to give exact jenv file to look
in for the admin secret, if the name is available; otherwise it will
fall back to the message from step 0.

User effect:

- Quickstart users continue to have best authentication experience.

- Users of newer Juju + GUI environments are told exactly where to look
for their admin secret (password).

- Users of older Juju environments with newer GUI are at least directed
to the right directory to find the appropriate jenv file with the admin
secret.

I think this bug can be closed on the GUI side once we do step 0. After that, we'll want to tackle the rest ASAP, but the bug itself will be (minimally) addressed by only the step 0 bit.
