Since the "admin account" use-case is a rather limited one (we
probably have 10.000 times the number of students compared to admins
for a given application) I usually recommend to use a second
webbrowser -- or a second instance or "private browsing" mode of the
same webbrowser -- which will not share state with the other instance
for admin account usage.
Beats ruining the SSO experience for everyone else (or running a
second IdP) any day for me.
