Extract TPM Owner Password from AD

I use BitLocker with AD integration on a 2003 sp2 Domain Controller. The
BitLocker Recovery Passwords and TPM Owner Passwords are stored successfully
in the AD. I installed BitLocker Recovery Password Viewer for Active
Directory to read the Recovery Passwords stored in the AD. Is there a
similar way to extract the TMP Owner Password? If I try to change the TPM
Owner PW on my Vista PC, I have to enter the Owner Password or point to a
TPM Password File. Because my Owner PW is stored in AD I have don't have
this information. What is the process to change the TPM Owner Password on my
Vista PC when I only have the TPM Owner Password stored in AD?
