Extracting service keys from Windows DC or AD

[akshar kanak]

 Dear Team
     Is it possible to directly extract  the service keys (secrect key
shared between KDC and target server) from windows 2003 Domain Controller or
Active directory for SPN cifs,smtpsvc,rpc, host etc  and place them in
keytab files which can be merged with Linux keytab file instead of
adding new service to the AD using ktpass.exe.

Thanks and Regards
Akshar
