Hi,

You could post directly to the form from site A and if it fails/pass have a redirect back to SiteA with error/success message:
action="http://www.siteb.com/logmein" method="post"

Use Ajax like "jairoh_" said, here a example

If you need shared authentication for both SiteA and SiteB then might be more tricky., but let me know and I see what I can come up with

Hope that helps
