Pfsense and SSO

[centuryx476]

Hello,
I ask this question here as I do not know where else to put it.

I have pfsense as my router/firewall.
I have owncloud and subsonic which I use for my private cloud and to JAM out to music out on the go.

Both owncloud and subsonic have LDAP to authenticate to Active Directory which I also have setup.

I want to make a website login page where I type in my user creds once (SSO) and I can access both owncloud and subsonic without having to type in my user creds for each one.

Can I leverage pfsense to do this at all ? If not what type of software can I use to accomplish this? Open source preferably.

Thank You
