What View client is being used and what version?
Also, would you mind adding the following log entry to your view_ssl_auth irule?
Within:
when HTTP_REQUEST_DATA {
after
if { $static::ViewSSL_Auth_debug > 1 } { log local0. "<$log_prefix>: In Request data"}
add
if { $static::ViewSSL_Auth_debug > 1 } { log local0. "<$log_prefix>: Payload equals [HTTP::payload]"}
I am looking to see if your payload is complete and contains "do-submit-authentication". If you want, please post the log after scrubbing the username and password which will be within the log.
thanks, Greg
