debug aaa detail enable - use this if there are authentication related issues with AAA server
debug aaa events enable - use this if there are authentication related issues with AAA server
debug aaa all enable - use this for auth issues; this is verbose so use it only when needed (i.e. for AAA override cases etc)
debug mobility handoff  - use when roaming issues between WLCs
 
Collect the output for the WLC show commands via the CLI:
 
config paging disable
show time
show client detail <mac-address of client> (note the client state on the WLC)
Ping the client from the WLC
