A PHP web page behind SSO is exposing a web form with about 71 fields. When submitting the form only the first 43 fields are passed to the PHP script while the 71 fields have been sent by the browser (checked using Firefox > developer > Network).
When tested on a server not behind SSO all the fields are passed properly.
The problem was also not detected when using OpenAM Web Agent/3.3.3. Policy agent has been upgraded to 4.0.0 in order to use virtual hosts in Apache.
