Often times, you may have custom attributes setup in Active Directory or some other source where your user profile information comes from.  Here’s how to map those custom attributes to profile properties in SharePoint 2010

• Log in to Central Administration
• Go to Manage Service Applications
• Click on your User Profile Service Application
• Click on ‘Manage User Properties’
• Scroll down the list of properties until you see the one you want to map and edit it.
• On the ‘Edit User Profile Property’ page, scroll to the bottom until you see the ‘Property Mapping for Synchronization’ section.
• If this section has the correct mapping listed then should go to Step 10.  If nothing is listed, then please proceed to the next step.
• The next section is the ‘Add New Mapping’ section.  Select the Source, Attribute, and Direction of the new mapping and click ‘Add’.  If no sources are available, ensure that you have setup the connection to your active directory instance.
• Once successfully added, click ‘OK’
• Go back to the User Profile Service Application page and start a Full Synchronization.
  • Start Profile Synchronization
  • Select ‘Start Full Synchronization’ and click ‘OK’.
  • Once the synchronization has completed, go to ‘Manage User Profiles’.
  • Find the name of the user you want to check for the imported attribute and choose ‘Edit My Profile’
  • Scroll down to the property that you imported and verify that the correct data is there.
