I have a large campus with 121 WAPs (1231 IOS). I am using Leap Authen which works great but some not all of the buildings are getting DHCP. I do not know why.
I can ping the DHCP server from any of the WAP's and keep in mind they are all configured the same and the configuration has been verified by Cisco and about 10 of the 36 buildings.
Ping DHCP Good
Ping ACS 3.2 doing Radius Good
Ping DGW Good
People on the wired network get an address fine. I do not know!
