My Mac machine fails on this test (master branch).

Just go test -v -run TestAuthInfoFromCtx in auth package.

Confirmed that this only happens in MacOS.

Nvm, my grpc-go local branch was somehow even with its master branch (git sha 844f573616520565fdc6fb4db242321b5456fd6d). Breaks from grpc/grpc-go@0c1d39d.
