Does anyone

know what would cause some clients to get this brower error when access the NAC Guest server sponser page?

"400 Bad request

Your browser sent a request that this server could not understand.

Size of a request header field exceeds server limit."

The NAC server has this error in the HTTPS log.

request failed: error reading the headers

Are you using Kerberos on Nac?

Then there is this bug: CSCtc26885 NAC Guest server sponsor AD SSO can fail with large kerberos tickets

Else it's a most likely browser problem, read this:
