[Matthew Paul Thomas <mpt@xxxxxxxxxxxxx>]

This problem goes back to February 2012, with a proposal that Ubuntu
could "cover most of the use cases which require the usage of dialogs"
using a new form of notification called a "snap decision" which would
have very limited interactivity, just two buttons. This was implemented
in the Ubuntu Touch toolkit, and real dialogs were correspondingly
deprioritized.

This was a mistake that is taking years to unwind.
<https://goo.gl/1qq24w> There was never a clear or useful dividing line
between dialogs that need just two buttons, those that need two buttons
and one text field, those that need two buttons one text field and one
checkbox, those that need two buttons a text field and a radio menu, and
so on.

For example, basic wi-fi authentication was implemented by adding the
ability for snap decisions to contain a single password field and a
single checkbox, in addition to the two buttons. But snap decisions are
fundamentally incapable of doing wi-fi password validation (bug
1091391), showing connection progress in the dialog, or displaying
connection errors (bug 1318732). And the kind of control combinations
and interactions required for WPA2 Enterprise authentication are
completely out of the question.

So, WPA2 Enterprise authentication is implemented in a completely
different way, using a proper dialog. Unfortunately the Mir developers
haven't yet implemented parentless dialogs, so the dialog needs a
parent, and that parent is System Settings. Besides looking disjointed,
this leads to the situation we have here, where System Settings hangs
around (and brings the rest of the session with it) when you haven't
even finished setting up the phone yet.

So, unfortunately, that something "works fine for plain PSKs" does not
mean it is even possible for it to "work equally and transparently even
for ... WPA2/Enterprise", because the UI is completely different code.

Fixing this requires implementing parentless dialogs, so that the
authentication dialog does not need a parent, and it can float on top of
the setup just as easily as it could float on top of System Settings, or
on top of any other app if you chose the network from the indicator
menu.

A workaround would be to duplicate -- and remember to sync any changes
to -- the WPA2 Enterprise authentication UI inside the unity8 shell, so
that the dialog could use the setup as its parent. That wouldn't solve
the problem for choosing the network from the network indicator. And
that a UI shell would need to know anything at all about wi-fi
authentication would be an architectural hack. (The shell already has
special knowledge of incoming phone calls, for the same reason.)

An alternative workaround would be to just prohibit you from connecting
to WPA Enterprise networks in the setup process at all. This would
require special-casing the network listing code (bug 1467438) so that it
hid, or greyed out, enterprise networks whenever it was being embedded
in the setup. It might also require adding a link to the setup screen,
explaining and maybe apologizing for the problem.

Title:
  Wifi for Enterprise APs cause the welcome wizard to exit into the main
  system

Status in indicator-network package in Ubuntu:
  Confirmed
Status in unity8 package in Ubuntu:
  New

Bug description:
  STEPS:
  1. Install a fresh image (post ota5)
  2. Start running the wizard
  3. Get to the wifi page and select an enterprise AP

  EXPECTED:
  I expect the wifi setup to return me to the welcome wizard

  ACTUAL:
  The DUT exits the welcome wizard, enters into system settings and on exit has you on the logged in phone.  Also pin setup is failed to be activated so the phone is insecure.
