What does donotcache flag do ?

[Shagun Akarsh]

Hello,

There is a donotcache flag being used in User password authentication flow.

Shibboleth IdPv3 documentation
<https://wiki.shibboleth.net/confluence/display/IDP30/PasswordAuthnConfiguration>
quotes "Name of the form field signaling to avoid caching the
authentication result for SSO, defaulting to donotcache".

So does this means
a) donotcache enables/disable SSO as per user request. (donotcache=true -->
SSO disabled, donotcache=false --> SSO enabled) Link
<http://shibboleth.1660669.n2.nabble.com/Reverse-logic-of-quot-donotcache-quot-checkbox-on-IdP-td7617977.html>
or
b) it caches the authentication success/failure (increases shib_idp_session
timeout) thus not prompting login screen for next application trying to
authenticate using IdP, something similar to remember me. If yes then for
what time ? (Switch aai reference link
<https://www.switch.ch/aai/support/presentations/shibboleth-training-2015/T3P06-Login_Form_Customization.pdf>
page 5 of 10 says donotcache = Don't Remember Login)
