I flashed one of my 5406 to 15_06_006, When I use firefox chrome or safari I now get "bad request" instead of web page.
these are all on snow leapard mac. I removed all cached stuff on chrome and it made no difference. Does web interface work for others out there using 15_06_006? Current auth setup is with local pw for web/offline and tacacs for ssh. This setup has been working on procurve for years.
