KRB5_SET_PASSWORD(3)	 BSD Library Functions Manual	  KRB5_SET_PASSWORD(3)

NAME
     krb5_change_password, krb5_set_password, krb5_set_password_using_ccache,
     krb5_passwd_result_to_string — change password functions

LIBRARY
     Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS
     #include <krb5.h>

     krb5_error_code
     krb5_change_password(krb5_context context, krb5_creds *creds,
	 char *newpw, int *result_code, krb5_data *result_code_string,
	 krb5_data *result_string);

     krb5_error_code
     krb5_set_password(krb5_context context, krb5_creds *creds, char *newpw,
	 krb5_principal targprinc, int *result_code,
	 krb5_data *result_code_string, krb5_data *result_string);

     krb5_error_code
     krb5_set_password_using_ccache(krb5_context context, krb5_ccache ccache,
	 char *newpw, krb5_principal targprinc, int *result_code,
	 krb5_data *result_code_string, krb5_data *result_string);

     const char *
     krb5_passwd_result_to_string(krb5_context context, int result);

DESCRIPTION
     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     the three functions, and use a newer version of the protocol (and also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 princi‐
     pal in creds.  The server principal of creds must be kadmin/changepw.

     krb5_set_password() and krb5_set_password_using_ccache() change the pass‐
     word 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 adminis‐
     trator, 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 describ‐
     ing the error code in result_code from the krb5_set_password() functions.
