Hi Chris,

This looks fine to me too. Thanks for taking care of this issue.

A potential issue I see is that the test might fail if
"localhost" does not resolve to the loopback address - but you
would likely get a "Connection refused" in that case.

One possibility to get that out of the way could be to use
the URIBuilder:

  * @library lib/ /test/lib


            URI providerURI = URIBuilder.newBuilder()

   59         env.put(Context.PROVIDER_URL, providerURI.toString());

best regards,

-- daniel

> According to failure logs, test already run done and give a pass message, but test framework caught “java.lang.RuntimeException: java.net.SocketException: Connection reset” from other thread during test end, go through the test code, LDAPServerHandler thread may throw such exception in specific case. This change will replace test itself implemented TestLDAPServer/LDAPServerHandler with customized BaseLdapServer to fix the corner. I had run the changed test on 4 platforms for total 600 times, no failure observed.
