Sharepoint & Alternative Mappings
Ok, here some more rambling on sharepoint. The sharepoint configuration I have (MOSS 2007 + windows 2008) has two site: one on port 80 (the intranet site with normal windows authentication (not AD mind you) and the other on port xxxx (and extranet site using forms authentication using ADAM). I have two normal DNS domains names: intranet.com and extranet.com (how original). The problem I got stuck with was how to map the port xxxx for the extranet site to so that externals could simply use port 80 on MOSS to view the site. Of course there are host headers but then I still got error messages from sharepoint.
In the end it turned out that Alternate Access Mappings (AAM) was the right way to do this.
After the break are the screen shots of the configurations that worked for me
