But for the #network admins out there, I'm curious: What's your take on captive portals for guest wireless in this day and age?
Personally, I've seen it cause a large number of end-user complaints a majority of the time it's implemented. I'd also question the legal efficacy, especially when a lot of companies are blindly throwing in a generic/default use agreement. I feel like I haven't seen as many guest networks leaning on captive portal as I used to.
Then again, I've been outside of most "enterprise networking" until last year, so I'd love to hear from folks who have been immersed in that area longer.
