Shibboleth SP getting progressively slower

Hi Scott,

sorry for resurrecting an old thread, however, I see another issue here,
besides having the possibility to have these two options
(maintainReverseIndex="false" or setting excludeReverseIndex).

Now I'm looking at logout, the reason for the reverse index to exist in
the first place. I have the default <Logout>SAML2 Local</Logout>
configured. When I explicitly call the /Shibboleeth.sso/Logout URL, it
very much seems that it is only the session itself and not the reverse
index belonging to the respective NameId being removed. I was doing a
load test including logout, and I see exactly the same behaviour as
without logout.

Just to confirm, is this correct? I'm a bit concerned, because *if* I
had an SLO compliant IdP, would there be no real SAML2 SLO of all active
sessions belonging to that user? Asking the other way round, why would
the SP, being unable to find a SLO URL at the IdP in my set-up, keep
itself from removing all sessions of the user?
