DESCRIPTION

32     These functions change the password for a given principal.
33
34     krb5_set_password() and krb5_set_password_using_ccache() are the newer of
35     the three functions, and use a newer version of the protocol (and also
36     fall back to the older set-password protocol if the newer protocol
37     doesn't work).
38
39     krb5_change_password() sets the password newpasswd for the client princi‐
40     pal in creds.  The server principal of creds must be kadmin/changepw.
41
42     krb5_set_password() and krb5_set_password_using_ccache() change the pass‐
43     word for the principal targprinc.
44
45     krb5_set_password() requires that the credential for
46     kadmin/changepw@REALM is in creds.  If the user caller isn't an adminis‐
47     trator, this credential needs to be an initial credential, see
48     krb5_get_init_creds(3) how to get such credentials.
49
50     krb5_set_password_using_ccache() will get the credential from ccache.
51
52     If targprinc is NULL, krb5_set_password_using_ccache() uses the the
53     default principal in ccache and krb5_set_password() uses the global the
54     default principal.
55
56     All three functions return an error in result_code and maybe an error
57     string to print in result_string.
58
59     krb5_passwd_result_to_string() returns an human readable string describ‐
60     ing the error code in result_code from the krb5_set_password() functions.
