[krbdev.mit.edu #7033] krb5 1.10 KRB5_PADATA_ENC_TIMESTAMP isn't working

[Arlene Berry via RT]

I pulled in the tip of 1.10 last week to try it out.  I'm seeing a problem with the KRB5_PADATA_ENC_TIMESTAMP preauth type.  We call krb5_get_init_creds_password after setting the preauth list to KRB5_PADATA_ENC_TIMESTAMP and it's reporting a loop error.  I debugged into it and verified that it attempts to do the requested preauth type which fails causing the loop.  I got down to lib/krb5/krb/gic_pwd.c at line 75 where krb5_get_as_key_password calls krb5_c_string_to_key_with_params and krb5_c_string_to_key_with_params reports bad enctype.  I checked and the requested enctype is 0.  The enctype is coming from the preauth rock where it's also 0 and that's as far as I got with it.
