"state" means something specific to OAuth2 and SAML so we don't
want to confuse developers who are working on this.
Also don't use "session" which could easily be confused with HTTP
cookies.
Let the server handle the state token instead of the connector. As a
result it can throw out bad requests earlier. It can also use that
token to determine which connector was used to generate the request
allowing all connectors to share the same callback URL.
Callbacks now all look like:
https://dex.example.com/callback
Instead of:
https://dex.example.com/callback/(connector id)
Even when multiple connectors are being used.
go-oidc sends an extra space before the list of scopes. This is bad
but we have to support it, so we'll be more lenient and ignore
duplicated whitespace.
Currently, whether or not a user has authenticated themselves through
a connector is indicated by a pointer being nil or non-nil. Instead
add an explicit flag that marks this.
Add a small program to iterate over the templates directory and
generate a go map of name to file data. This is so we can compile
these templates into the dex binary instead of requiring files on
disk.
Also add a Makefile rule to do this automatically.
As we've seen on master it's very easy mistakenly make changes that
assume root URL paths. Run server integration tests at a non-root
issuer URL to prevent this.
