Changing passwords in MS KDC from MIT krb5

[Curtis Robinson]

Ok, I have the code necessary to take the password set in iPlanet
Directory Server.  I have the sample MS code to change the password
for the users.  What I am having trouble is the functions necessary to
transform the admin username and password to the krb5_ccache variable
out to feed to the MS change password function? 

Function for setting password:
int set_passwd (char *targpname,
                char *passwd_new)

Create these variables:

    krb5_error_code ret;
    krb5_context context;
    char pname[] = "administrator";
    char passwd[] = "secret";
    krb5_ccache ccache;
    krb5_principal targprinc, princ;
    int result_code;
    krb5_data result_code_string, result_string;

Create the context with:
krb5_init_context(&context);

krb5_parse_name (context, pname, &princ);
krb5_parse_name (context, targpname, &targprinc);

Something between this gets the krb5_ccache from the pname and passwd.

Set the password (MS Function):
ret = krb5_set_password(context, ccache, passwd_new, targprinc,
                                &result_code, &result_code_string,
                                &result_string)
