SimpleSAMLphp, Symfony 2 and Session information lost

[Boy Baukema]

Hi,

Just posting this for Google to index but we had an issue integrating SimpleSAMLphp 1.13 with Symfony 2.6 always giving "State information lost".

Our SF2 project was first setup using the memcached session handler but we wanted multi-tenancy which the memcached session handler will only support in the upcoming SSP 1.14.

So we decided to try the default phpsession session handler.

Unfortunately this always gave us "State information lost".

After much debugging it turned out that this issue http://trac.symfony-project.org/ticket/9021 is still present in Symfony2.

SSP tries to write to the session after Symfony closes the session.

Switching Symfony2 to use the PHP bridge session handler makes it work.

Cheers,

Boy
