>Subject: [PATCH] Bug 28735: Self-checkout users can access opac-user.pl for
> sco user when not using AutoSelfCheckID
>
>This patch makes the sandboxing of the selfcheckout more robust by
>adding a "sco_user" session variable which is turned on when
>logging into the self-checkout (either by AutoSelfCheckAllowed or manually).
>
>If a user with this session variable turned on tries to access
>other parts of the system (like the rest of the OPAC), it will
>"kick out", so that the browser user will lose the authenticated session.
>
>Test plan:
>1) Apply the patch
>2) koha-plack --restart kohadev
>3) Go to http://localhost:8080/cgi-bin/koha/sco/sco-main.pl
>4) Note that you are logged into the self-checkout
>     So you see the login screen specific to the self-checkout.
>     To log with the actual patron. It's a nested auth.
>5) Go to http://localhost:8080/cgi-bin/koha/opac-main.pl
>6) Note that you are not logged into the OPAC
>7) Log into the staff interface and disable the
>system preference AutoSelfCheckAllowed
>8) Log out of the staff interface (this step is very important)
>9) Go to http://localhost:8080/cgi-bin/koha/sco/sco-main.pl
>10) Note that you are prompted to log into Koha
>11) Login using the "koha" user (when using koha-testing-docker)
>12) Note that you are logged into the self-checkout
>13) Go to http://localhost:8080/cgi-bin/koha/opac-main.pl
>14) Note that you are not logged into the OPAC
>      Without the patch you would still be logged as "koha"
>15) Go back to http://localhost:8080/cgi-bin/koha/sco/sco-main.pl
>16) Note that you will need to log in again as you've lost your
>session cookie
>      Without the patch you will still be logged in the self-checkout
>Voila!
