session.state.timeout never work as described in the comment.

[Kojiro-Goto]

When session.state.timeout time passed after accessing IdP login page, you can't process
authentication and IdP(SSP) sends redirect response and show login page again.
My understanding for this parameter is above.

Latest version of SSP doesn't perform as above so this means that session.state.timeout has no meaning.
This change comes from commit: 3c52b28

Questions:

1. Is this latest SSP design?
2. Is this an issue?

How to reproduce:

1. set 60 for session.state.duration
   'session.state.timeout' => 60

2. Using ldap:LDAP module for authentication

3. Access to the IdP. (IdP Shows login page)

4. Wait 60 seconds.

5. Input any id and any password

Old version (before commit: 3c52b28) works fine. (Redirect same URL)
Latest version (after commit: 3c52b28) perform authentication process.

Thanks,
