'special' salt type

[Rahul S]

Hi,
   Is it possible to create a new principal with user supplied salt.
Looks like the code has a salt type 'special' but kadmin.local is not
accepting it.

kadmin.local:  ank -e des-cbc-crc:special user2
WARNING: no policy specified for user2 at realm1; defaulting to no policy
Enter password for principal "user2 at realm1":
Re-enter password for principal "user2 at realm1":
add_principal: Unsupported salt type while creating "user2 at realm1".

Regards,

-Rahul S.
