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.
Accept the following response_type for the implicit flow:
id_token
token id_token
And the following for hybrid flow
code id_token
code token
code token id_token
This corrects the previous behavior of the implicit flow, which
only accepted "token" (now correctly rejected).
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.
Ensure compared times are within a second of one another instead of
rounding, which can flake if the two times are different enough to
do round to different values.
Tested using the golang.org/x/tools/cmd/stress tool.
The following set of commands fail without this patch:
$ go get golang.org/x/tools/cmd/stress
$ go test -o server.test github.com/coreos/dex/server

Closes#699
Instead of throwing a 500 error if a user enters an invalid name,
display the same text box as if the user had entered the wrong
password.
NOTE: An invalid username now returns much quicker than an invalid
password. Consider adding an arbitrary sleep in the future if we
care about masking which was invalid.
"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.
fixes: #636
This commit addresses a problem where the `max-age` value is being set
in nanoseconds as opposed to seconds, as required by the specification.
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.
