The server implements a strategy called "Refresh Token Rotation" to
ensure refresh tokens can only be claimed once.
ref: https://tools.ietf.org/html/rfc6819#section-5.2.2.3
Previously "refresh_token" values in token responses where just the
ID of the internal refresh object. To implement rotation, when a
client redeemed a refresh token, the object would be deleted, a new
one created, and the new ID returned as the new "refresh_token".
However, this means there was no consistent ID for refresh tokens
internally, making things like foreign keys very hard to implement.
This is problematic for revocation features like showing all the
refresh tokens a user or client has out.
This PR updates the "refresh_token" to be an encoded protobuf
message, which holds the internal ID and a nonce. When a refresh
token is used, the nonce is updated to prevent reuse, but the ID
remains the same. Additionally it adds the timestamp of each
token's last use.
Introducing glide-vc caused us to unknowingly removed our Go
protobuf compiler (since it's a main). Add flags to glide-vc usage
to remedy this.
Since we now require several glide and glide-vc flags, add a Makfile
target and tests to catch when PRs don't use the correct flags.
Add a script to check the Go version before building dex. This
gives a nice error message rather than just failing to compile.
With changes:
$ go version
go version go1.6.4 linux/amd64
$ make
ERROR: dex requires Go version 1.7+. Please update your Go installation: https://golang.org/dl/
Makefile:93: recipe for target 'check-go-version' failed
make: *** [check-go-version] Error 2
Checks only added for building the actual binary, not tests, since
this is aimed at users just starting off with the project.
This PR reworks the web layout so static files can be provided and
a "themes" directory to allow a certain degree of control over logos,
styles, etc.
This PR does NOT add general support for frontend customization,
only enough to allow us to start exploring theming internally.
The dex binary also must now be run from the root directory since
templates are no longer "compiled into" the binary.
The docker image has been updated with frontend assets.
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.
It's not clear that the best way to manage clients is through a
gRPC based command line tool. For example we may explore an admin
dashboard and enable bootstrapping through static clients.
For now use static clients while we hold off on a more concrete
proposal.
