Using SharePoint Site across domains

Question

We have a SharePoint site in a domain where most of the users are located.

A few users are in a different domain.

Is it possible to give these users access to the site? Does it require a trust between the domains?

Answer 1

Here is an article I wrote a while back to pull together resources for supporting multiple domains. http://www.mikeoryszak.com/sharepoint/supporting-multiple-active-directory-domains

Answer 2

If you want the additional users on the different domain to use Windows authentication,then yes you will need a trust relationship between the domains. You could also use Forms Based Authentication for the subset group if the trust is not an option for you.
