See the README for usage with Dex or any other OIDC provider.

To test run a backend:

    python3 -m http.server

Run dex and modify the example config with the proxy callback:

    go get github.com/coreos/dex/cmd/dex
    cd $GOPATH/src/github.com/coreos/dex
    sed -i.bak \
      's|http://127.0.0.1:5555/callback|http://127.0.0.1:5555/oauth2/callback|g' \
       examples/config-dev.yaml
    make
    ./bin/dex serve examples/config-dev.yaml

Then run the oauth2_proxy

    oauth2_proxy \
      --oidc-issuer-url http://127.0.0.1:5556/dex \
      --upstream http://localhost:8000 \
      --client-id example-app \
      --client-secret ZXhhbXBsZS1hcHAtc2VjcmV0 \
      --cookie-secret foo \
      --email-domain '*' \
      --http-address http://127.0.0.1:5555 \
      --redirect-url http://127.0.0.1:5555/oauth2/callback \
      --cookie-secure=false

Login with the username/password "admin@example.com:password"

#369: Optionally allow skipping authentication for preflight requests

various fixes for getting Nginx auth_request mode working

This is useful in Nginx auth_request mode, if a 401 handler is
configured to redirect to the sign-in page. As the request URL
does not reflect the actual URL, the value is taken from the
header "X-Auth-Request-Redirect" instead. Based on #247

This is enhancement of #173 to use "Auth Request" consistently in
the command-line option, configuration file and response headers.
It always sets the X-Auth-Request-User response header and if the
email is available, sets X-Auth-Request-Email as well.

Skip 404 errors when looking up Google groups

Improve redirect checks

When checking user membership against Google groups the groups are checked one
at a time and in the order that they were supplied. If one of the groups does
not exist then the checking is halted with the following error.

google.go:201: googleapi: Error 404: Resource Not Found: groupKey, notFound

None of the groups following the missing group are checked either. This means
that something as trivial as a typo in the first group will make it impossible
for anybody to login.

This change catches the 404, logs a message, and then carries on as usual. In
this way a typo will cause a particular group to stop working but will not
affect any other groups.

Update vendored dependencies.

This fixes a test w request signing due to a content-length:0 header from Go 1.8

dist.sh and Godeps updates

golang.org/x/oauth2/google is same repo as golang.org/x/oauth2
  - this sometimes confused gpm/git

cloud.google.com/go/compute/metadata is a missing dependency
of golang.org/x/oauth2

so gpm is not affected if module exists in user's GOPATH already
