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

     krb5_change_password, krb5_set_password, krb5_set_password_using_ccache,
     krb5_passwd_result_to_string -- change password functions

     Kerberos 5 Library (libkrb5, -lkrb5)

     #include <krb5/krb5.h>

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

     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_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);

     These functions change the password for a given principal.

     krb5_set_password() and krb5_set_password_using_ccache() are the newer of the three func-
     tions, and use a newer version of the protocol (and also fall back to the older set-password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 princi-
     pal 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

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