Before, you could not POST your credentials to a password-connector's
endpoint without GETing that endpoint first. While this makes sense for
browser clients; automated interactions with Dex don't need to look at
the password form to fill it in.
A symptom of that missing GET was that the POST succeeded (!) with
login successful: connector "", username="admin", email="admin@example.com", groups=[]
Note the connector "". A subsequent call to finalizeLogin would then
fail with
connector with ID "" not found: failed to get connector object from storage: not found
Now, the connector ID of an auth request will be updated for both GETs
and POSTs.

connector/microsoft implements authorization strategy via Microsoft's
OAuth2 endpoint + Graph API. It allows to choose what kind of tenants
are allowed to authenticate in Dex via Microsoft:
* common - both personal and business/school accounts
* organizations - only business/school accounts
* consumers - only personal accounts
* <tenant uuid> - only account of specific tenant

This way, the user who has selected, say, "Log in with Email" can make up
their mind, and select a different connector instead.
However, if there's only one connector set up, none of this makes sense -- and
the link will thus not be displayed.

This allows users of the LDAP connector to give users of Dex' login
prompt an idea of what they should enter for a username.
Before, irregardless of how the LDAP connector was set up, the prompt
was
Username
[_________________]
Password
[_________________]
Now, this is configurable, and can be used to say "MyCorp SSO Login" if
that's what it is.
If it's not configured, it will default to "Username".
For the passwordDB connector (local users), it is set to "Email
Address", since this is what it uses.

connector/linkedin implements authorization strategy via LinkedIn's
OAuth2 endpoint + profile API.
It doesn't implement RefreshConnector as LinkedIn doesn't provide any
refresh token at all (https://developer.linkedin.com/docs/oauth2, Step 5
— Refresh your Access Tokens) and recommends ordinary AuthCode exchange
flow when token refresh is required.

The bcrypt hashing algorithm runtime grows exponentially with cost,
and might cause a timeout if the cost is too high. Notifying the user
of high cost and of long running calculations will help with tuning
and debugging.
Switch from using "text/template" to "html/template", which provides
basic XSS preventions. We haven't identified any particular place
where unsanitized user data is rendered to the frontend. This is
just a preventative step.
At the same time, make more templates take pure URL instead of
forming an URL themselves using an "authReqID" argument. This will
help us stop using the auth req ID in certain places, preventing
garbage collection from killing login flows that wait too long at
the login screen.
Also increase the login session window (time between initial
redirect and the user logging in) from 30 minutes to 24 hours,
and display a more helpful error message when the session expires.
How to test:
1. Spin up dex and example with examples/config-dev.yaml.
2. Login through both the password prompt and the direct redirect.
3. Edit examples/config-dev.yaml removing the "connectors" section.
4. Ensure you can still login with a password.
(email/password is "admin@example.com" and "password")
The "at_hash" claim, which provides hash verification for the
"access_token," is a required claim for implicit and hybrid flow
requests. Previously we did not include it (against spec). This
PR implements the "at_hash" logic and adds the claim to all
responses.
As a cleanup, it also moves some JOSE signing logic out of the
storage package and into the server package.
For details see:
https://openid.net/specs/openid-connect-core-1_0.html#ImplicitIDToken
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.

^C
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.
