Traveling between locations without re-signing in to SSID
I have 9 locations and our users travel between them. I currently have a ZD1100 controlling 19 APs across the 9 locations that are getting rather old. Users are able to travel to any site without having to sign into each site. If I setup unleased APs in each location with the same ssid and password, will users be able to go between locations with out signing in to each site?
