In my previous post ‘Adding Active Directory Accounts to SharePoint‘ I outlined how you can first create AD accounts then add them to SharePoint 2007. Since the AD portion still stays the same this will outline how to add users to your SharePoint instance.
Log onto your server with appropriate administrator right to add SharePoint accounts and click: Site Actions>Site Settings>Users and Permissions>People and groups. You will land in the ‘Visitors’ group page.
We can see that by default we land into the ‘Visitors’ group. By default there are three groups in a SharePoint site.
To add our existing AD account select the appropriate group and press ‘New’. Add in the appropriate user account information.
From this windows you can options you can select and press OK:
If you need to grant direct permissions outside of a group go to Site Actions->Site Permissions->Grant Permissions
You now have a AD account that is part of your SharePoint site.
