My client has a drupal 6 site. This is used with there clients to project manage projects. We are building a new main website for our client using drupal (6/7 yet to be decided). They wish to have a login box on the home page of there new website that will log you into the project manage site. So something like:
Go to main website Enter user name and password for project site Website changes to project site with user logged in.
Would this be possible? The user would not have a login on the main site.
Both sites would be running on the same machine. Part of me is thinking that maybe multi-site could be my answer.
