https://github.com/coder/coder/pull/15608 introduced a buggy behaviour
with dbcrypt enabled.
When clearing an oauth refresh token, we had been setting the value to
the empty string.
The database encryption package considers decrypting an empty string to
be an error, as an empty encrypted string value will still have a nonce
associated with it and thus not actually be empty when stored at rest.
Instead of 'deleting' the refresh token, 'update' it to be the empty
string.
This plays nicely with dbcrypt.
It also adds a 'utility test' in the dbcrypt package to help encrypt a
value. This was useful when manually fixing users affected by this bug
on our dogfood instance.
Once a token refresh fails, we remove the `oauth_refresh_token` from the
database. This will prevent the token from hitting the IDP for
subsequent refresh attempts.
Without this change, a bad script can cause a failing token to hit a
remote IDP repeatedly with each `git` operation. With this change, after
the first hit, subsequent hits will fail locally, and never contact the
IDP.
The solution in both cases is to authenticate the external auth link. So
the resolution is the same as before.
* chore: verify pass through external auth query params
Unit test added to verify behavior of query params set in the
auth url for external apps. This behavior is intended to specifically
support Auth0 audience query param.
* feat: allow external services to be authable
* Refactor external auth config structure for defaults
* Add support for new config properties
* Change the name of external auth
* Move externalauth -> external-auth
* Run gen
* Fix tests
* Fix MW tests
* Fix git auth redirect
* Fix lint
* Fix name
* Allow any ID
* Fix invalid type test
* Fix e2e tests
* Fix comments
* Fix colors
* Allow accepting any type as string
* Run gen
* Fix href
