>
> The SimpleCachedLDAPAuthorizationMap attempts to cache the LDAP
> authentication data; however, the locking used in the update phase can lead
> the broker to stall message dispatch since every caller that looks up
> security ACLs will wait until the update completes. Since we are caching the
> updates should occur asynchronously and only replace the existing cached
> values once the update completes.
