Thanks for opening up this PR! Happy to merge this in, just want to clean up the unneeded line!

@mtodd Hear you are, bro~

@wuranbo build is red, probably because it needs master merged in. Doesn't seem related to the diff.

@mtodd I tried to rebase impertinently. But it turns out that it's not the reason. So I check the two CI failure, https://travis-ci.org/github/github-ldap/builds/65865839, https://travis-ci.org/github/github-ldap/builds/65998284。

The reason of this two failure were the CI env.Travis CI run apt-get update failed.
