Hello,
I work at this university and I'm seeking an effective solution for an internet login mechanism.

We have a leased-link at our campus, which is shared by both staff & students. All systems (desktops + laptops + handhelds) connect to the internal network via wifi and can then get onto the net.

However, a local govt. regulation requires us to keep track of individual internet usage and hence we need a solution (pref. free / opensource) that'll enable us to implement some sort of an authentication mechanism once a user hooks onto the network.

One requirement is that the software should be able to authenticate either against LDAP or some other custom user database (MySQL based) or both.

Can anyone suggest any such software or mechanism? Most of our servers are Linux based... so something that runs off such a platform will be good.

Thanks, m^e
