Use ADRA to restore individual objects from ADAM/AD LDS.
To restore individual objects from an ADAM/AD LDS backup
On the navigation bar, click the down arrow next to Restore.
In the View by Resource pane, double-click Active Directory Application Mode.
In the Results pane, select the appropriate object or objects.
Click Run Now to start the restore job or select other restore options from the Properties pane.
Any Active Directory or ADAM/AD LDS object or property that is selected for restore will overwrite existing objects and properties, even if you selected Skip if file exists or Skip if existing file is more recent on the General Restore Job Properties dialog box.
If you restored a deleted user object, use the ADSI Edit application to reset the object's user password and re-enable the object's user account.
