Is this behavior from Single Sign On (SSO)or is it built into your form? SSO will ask for your domain username and password. If it is a form behavior there is probably a page dedicated to log in somewhere in the form. It will probably be the first page of the form. “Turning it off” will depend on what “it” is. You can export the form design http://www.perfectforms.com/Documentation/manual/html/?d_exportingformsandformdata.htm and attach a copy of the .PF file to a support inquiry http://www.perfectforms.com/support_contact.php and I can review it for you.
