Info about SLO on IPDv4 - no final logout response

[iljkr at tiscali.it]

  I have this scenario:
-a Shibboleth IDPv4
-two SP: SP_A and SP_B
(Shibbolet SP v2 with apache)

And I have access to resources protected
by both SPs with a successful SSO login.

I start an sp initiated logout
from SP_A, with the help of SAML tracer this is what happens:

1) SP_A
sends a SAML Logout Request to the IDP
2) IDP show me an html page based
on logout.vm template and I choose to also disconnect the other sp
3)
IDP sends a SAML Logout Request to the SP_B, SP_B sends a SAML Logout
Response to the IDP (with status Success)
4) IDP shows me an html page
based on logout-propagate-vm template, with the message Attempting to
log out of the following services: 1. SP_B

I expected the idp to send a
logout response to the SP_A to conclude, but this doesn't happen.

Is
this a known issue or a problem with my deployment?
