Shibboleth IdP configuration with simplified backend

[Marek Denis]

Hello,

As I am playing with ECP extensions at the moment, I am trying to
deploy my own Shibboleth Identity Provider Server in order to have a
controllable IdP with access to the logs.
So to speak what I am interested in, is a simplified configuration of
the IdP with set of 2-3 users. So far I have seen configurations with
the LDAP used as a backend. I don't really need LDAP, and I don't want
to spend time configuring it.
I would be extremely happy with some docs/examples for a static
configuration (with flat files) or simple references for MySQL
configurations. Anybody?

Maybe, instead of installing my own IdP there is a publicly available
IdP with ECP enabled (just like testshib.org is enabled for normal
webSSO configuration)?

Thank you,
