Why use a Common Login Site?
Many companies have multiple GroveSite sites within their GroveSite 'Organization'. Within an Organization, each site is uniquely addressable by a URL structured as:
https://secure.grovesite.com/orgshortname/siteshortname
For example, consulting firm Golden Associates may have multiple sites, one for each client engagement. So their site URLs would look like:
https://secure.grovesite.com/goldenassociates/abcclient
Members who are enrolled in multiple sites -- sometimes tens or even hundreds of sites -- may find it burdensome to remember or bookmark each site's URL.
Provide a single URL through a Common Login Site
With a Common Login Site, you can give all members an additional option, to simply go to:
https://secure.grovesite.com/orgshortname
In our example:
https://secure.grovesite.com/goldenassociates OR http://goldenassociates.grovesite.com
