> SASL library generates un-necessary DNS and LDAP requests
> ---------------------------------------------------------
>
> Key: DISPATCH-244
> URL: https://issues.apache.org/jira/browse/DISPATCH-244
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Tests
> Affects Versions: 0.5

> The dispatch system tests (e.g. system_tests_management) run very slowly when
> connected to a VPN.
> - about 10x slower on VPN configured to use TCP connection
> - about 5x slower on VPN configured for UDP connection
> Wireshark shows unexpected LDAP and DNS queries on the VPN interface.
> `wallace` below is the local host name, but is not mentioned in any tests so
> must be picked up by proton or dispatch at runtime:
> {code}
> 1 0.000000000 10.3.113.108 10.11.6.1 LDAP 242
> searchRequest(11) "dc=redhat,dc=com" wholeSubtree
> 2 0.035161000 10.3.113.108 10.5.30.160 DNS 72
> Standard query 0xd03f A wallace.lab.bos.redhat.com
> {code}
