Type: Technical
Reported by: Maurizio Brigandi' <[email protected]>

Section: 6

Original Text
-------------

         leaf-list user-authentication-order {
           type identityref {
             base authentication-method;
           }
           must '(. != "sys:radius" or ../../radius/server)' 



Corrected Text
--------------

         leaf-list user-authentication-order {
           type identityref {
             base authentication-method;
           }
           must '(not(. = "sys:radius") or ../../radius/server)'
 

Notes
-----
As indicated in https://www.w3.org/TR/1999/REC-xpath-19991116/#booleans

the following expression comparing a node-set with a string

       . != "sys:radius"

is true if at least one node in the node-set satisfies the boolean expression.

This is not the intention of the "must" condition.

It is necessary to use not(. = "sys:radius") to achieve the right intention of 
the check.

Instructions:
-------------
This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party
