KRB5_SET_PASSWORD(3)	    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       of  the	three  functions, and use a newer version of the protocol (and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 prin-
       cipal 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	admin-
       istrator,  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 de-
       fault 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  de-
       scribing	 the  error  code  in result_code from the krb5_set_password()
       functions.
