I've got a fairly simple SharePoint 2010 farm set up: 2 WFE servers with Network Load Balancing hosting the main portal site.
As per Microsoft's best practice recommendations I've set up My Sites in a separate web application. As some of the user base are not using domain joined PCs they have to login once for the portal (http://portal) and then again when the access My Sites since they're crossing in to a separate web application on a separate host (http://mysite). Portal & MySite are both hosted on the same physical WFE servers.
Is there an easy way to set up some thing to stop this happening and just have them login once?
I understand that there's plans for us to deploy ISA in the not too distant future - could we use ISA to manage authentication to the two sites so that the users only need to log in once?
