This tip is for SharePoint Server 2010.
I had this post sitting for a bit in my drafts and decided I should put it out there.
User profiles have been getting a lot of attention with SharePoint 2010. In this post I am going to show you how you can create your very own Active Directory attribute, map that attribute to the FIM client SharePoint 2010 uses to import profile information and get that attribute into SharePoint.
In some cases you will already have an Active Directory attribute and just want to map in to SharePoint. In that case you can start with step 6.
Drop down the menu for the profile and Edit My Profile.
