>                 URL: https://issues.apache.org/jira/browse/DISPATCH-1011
>             Project: Qpid Dispatch
>          Issue Type: Bug
>          Components: Policy Engine
>    Affects Versions: 1.0.1
>            Reporter: Chuck Rolke
>            Assignee: Chuck Rolke
>            Priority: Major
> If a username is a substring of a policy rule's static text then the username substitution
fails. For example:
> {{    if (!_qd_policy_approve_link_name("em", "temp-${user}", "temp-em"))}}
> {{        return "proposed link 'temp-em' should match allowed links with ${user}
but does not";}}
> Since the username *em* is found in the fixed text of *temp-* then the substitution logic
goes awry and the match fails. Thanks to aconway for making this observation.
