Can't find "oidc" auth provider

[mehdideveloper]

Hey
I tried running the tool on my but it gives me this error:

...
Testing for unauthenticated access...
panic: No Auth Provider found for name "oidc"

which happens inside the `kubernetes.NewForConfig" call.

I checked my config file and it actually contains an auth provider called oidc

Hi,

Sorry, right now the tool only works when using mutual TLS for authenticating with the apiserver.

I also ran into this issue, though in my case the missing Auth Provider was GCP. Based on this comment, it seems that client-go doesn't include all auth providers by default, but one can import them as needed:

// Import just the GCP provider.
_ "k8s.io/client-go/plugin/pkg/client/auth/gcp"
// Or import all providers.
_ "k8s.io/client-go/plugin/pkg/client/auth"

I added the latter import to main.go and when I re-ran the tool I got the following error:

$ go run main.go
# github.com/gravitational/cve-2018-1002105/vendor/k8s.io/client-go/plugin/pkg/client/auth/azure

vendor/k8s.io/client-go/plugin/pkg/client/auth/azure/azure.go:266:23: cannot use token.token.ExpiresOn (type json.Number) as type string in assignment

Some more googling led me to the following update for Gopkg.toml:

[[override]]
name = "github.com/Azure/go-autorest"
revision = "bca49d5b51a50dc5bb17bbf6204c711c6dbded06"

After running dep ensure to update the dependencies I was able to run the tool successfully. Hopefully that helps!
