krb5_change_password, krb5_set_password, krb5_set_password_using_ccache, krb5_passwd_result_to_string —

       These functions change the password for a given principal.

       krb5_set_password()  and krb5_set_password_using_ccache() are the newer of the three functions, and use a
       newer version of the protocol (and also fall back  to  the  older  set-password  protocol  if  the  newer
       protocol doesn't work).

       krb5_change_password()  sets  the  password  newpasswd  for  the  client  principal in creds.  The server
       principal of creds must be kadmin/changepw.

       krb5_set_password() and krb5_set_password_using_ccache() change the password for the principal targprinc.

       krb5_set_password() requires that the credential for kadmin/changepw@REALM is  in  creds.   If  the  user
       caller   isn't   an   administrator,   this   credential   needs   to   be  an  initial  credential,  see
       krb5_get_init_creds(3) how to get such credentials.

       krb5_set_password_using_ccache() will get the credential from ccache.

       If targprinc is NULL, krb5_set_password_using_ccache() uses the  the  default  principal  in  ccache  and
       krb5_set_password() uses the global the default principal.

       All three functions return an error in result_code and maybe an error string to print in result_string.

       krb5_passwd_result_to_string()  returns an human readable string describing the error code in result_code
       from the krb5_set_password() functions.
