There is a request to use an alternate port binding, instead of the default 443. This has never been a problem in the past but this is the latest release of Laserfiche.
It still works fine with Forms by updating the Forms URL in the config to include the port in the URL
However in web client, even if you specify https://domain:port/laserfiche in the Laserfiche Web Client URL and https://domain:port/LFDSSTS/ in the Directory Server configuration it still removes the :port in the browser when you visit the website, trying to default back to the 443 port
Forms works fine, with STS and everything. Web Client, first thing it does when you visit the site is removes your port specification from the URL and then complain that https://domain/laserfiche does not exist.
