All of our campuses currently use 2 WLAN's; one for staff and one for guest - each location has their own passphrase with WPA2-psk with AES encryption.
I'm testing out a config right now whereby a staff or faculty member would login to our staff network via CP then use their LDAP credentials and be placed in the 802.1x authenticated role - the same would apply for our students but they would most likely fall in to the guest role or a similar.
I really like the idea of LDAP authentication; it allows us as an IT dept to track and log who's on our network and it gives users the abiltiy to move from campus to campus w/out having to remember the passphrases. I'm just no sure if this is secure and I'm also wondering if anyone on here might have some thoughts on this.
