Hi,

I'm not sure if this is relevant, but Firefox preserves session
cookies across browser restarts. This was discussed on the Security
Now! podcast recently:

Search for 'sessionstore' and read a little before and after.

Are session cookies relevant for kerberos authentication?

It's only tangentially relevant. IPA does use session cookies. IPA logout destroys the session on the server making the session cookie stored in the browser invalid.

However, SSO (Single Sign-On) continues to work as it's supposed to. As long as you have valid credentials in your kerberos cache you'll be automatically logged in (albeit with a brand new session and session cookie). All this is by design.

You can logout of IPA which destroys your session, but unless you also destroy your credentials the automatic SSO process will be applied the next time you visit the web UI.
