About krb5 api

[shavingha]

     I'm using kerberos to development a simple ,  application easy to use( generally, for add principal, change password, add so on,  with GUI),But I did not know how to using the SDK(or API) for windows 2000, do you have some suggestion or sample? 
     
     I have gotten some document from non-official website,  But It can not work properly with the source code. 
Can you help me? Thanks a lot.

    Yours shavingha
