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krb5_set_password and krb5_set_password_using_ccache are the newer of the three functions, and use a newer version of the protocol (and also fall back to the older set-password protocol if the newer protocol doesn’t work).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