preauthentication when using keytab

[Michal Vocu <michal@karlin.mff.cuni.cz>]

Hello,
  when going through the heimdal (0.1m) sources I have noticed that 
there is some piece of code in krb5_get_init_creds_password() 
dealing with required preauthentication, but nothing similar 
in krb5_get_init_creds_password().
We are using KDC which requires preauthentication and we have had some
problems when using keytabs to authenticate to KDC. I wonder if it would
be possible to add the same code to krb5_get_init_creds_password() (I
have a patch for that) or even better to move that code to
krb5_get_in_cred() (I think that MIT code does this in
krb5_get_in_tkt()). I can make a patch for this as well if you think it
is reasonable.

Best regards,

Michal
