James C. Wu commented on DIRKRB-94:
-----------------------------------

Active Directory use ktpass for generating keytab file. The command works as 
follows: 

ktpass -out {keytab-file-to-produce} -princ 
{Service-Principal-Name}@{the-kerberos-realm} -mapUser {AD-user} -mapOp set 
-pass {AD-user-password} -crypto RC4-HMAC-NT -pType KRB5_NT_PRINCIPAL

On linux, there is java tool ktab that works similarly to ktpass. For example, 
[root@wssecjibe bin]# ./ktab -a 
HTTP/[email protected] ot56prod -k /etc/krb5.keytab
Done!
Service key for principal HTTP/[email protected] 
saved

ot56prod is the password for the principle. 

But they all require the password of the principle. I would like to have a tool 
that I can dump the keytab file if I have admin credential to the KDC.

> As an administrator, I should be able to export the keytab of any Kerberos 
> principle without having to know their password. 
> The keytab can either be generated in an interactive way like Kadmin or can 
> be generated through a script provided the right credential.
