cmd/dex/serve.go:116: invalid operation: conn.ID == nil (mismatched types string and nil)

[ericchiang]

Thanks for the PR! ID is a string so you'll have to do conn.ID == ""

Updates #681

D'oh! I guess it helps to make sure the code compiles before I send a PR.

[ericchiang]

@cjyar that's why we have CI :)

@cjyar can you squash and edit the commit message to begin with cmd/dex. That's just a CoreOS style thing. For example

cmd/dex: validate that connectors have an ID

[cjyar]

@ericchiang It won't let me. I can squash them in my repo, delete this PR, and make a new one. Or you can squash them on your end with the pulldown on the "Merge pull request" button. That button doesn't show up for me, because I don't have permission to merge into your repo.

@cjyar You can squash them locally on your workstation and force push to the master branch on your fork under @cjyar. That will then update this PR with a squashed version with the requested changes.

@SEJeff Thanks for the tip!

lgtm!
