decrypting the user password

[Asmaa Ahmed]

Hello,
I am having kerberos MIT integrated to LDAP as a backend which is good so far.The problem that I have some applications doesn't support Kerberos to restore the user credentials.I wonder if I can decrypt the password from Kerberos server manually to have it in a plaintext, so I can do some password sync between Kerberos/ldap server and the application DB!!!My target is having a script or so to get all the original kerberos principals passwords. 
Thanks.
