This script was donated by a customer to enumerates bitlocker information and populates 2 virtual attributes to store the RecoveryGUID and RecoveryPassword bitlocker information in 2 virtual attributes of DRA.   To leverage the script, first create 2 virtual attributes for Computer Objects called "RecoveryGUID" and "RecoveryPassword"   Next edit the script and update the values in the script for for your environment.   The 2 items to modify are:

OnePointsrv = "DRA SERVER NAME"

and the LDAP query line, replace the 'LDAP://DC=DOMAIN NAME' with your domain information.  

Also notice the script looks to see if the computer object is located in a "Workstations" OU.   This will need to be modified for your environment.
