In addition to the specific permissions that are already mentioned, the project also needs the `iam.googleapis.com` API enabled, otherwise authenticating will fail with an error similar to:
```
Error authenticating: Error making API request.
URL: PUT https://localhost:8200/v1/auth/gcp/login
Code: 400. Errors:
* could not find service account key or Google Oauth cert with given 'kid' id
```
Specifying the `allowed_organiztaional_units` parameter to a cert auth
backend role will require client certificates to contain at least one of
a list of one or more "organizational units" (OU).
Example use cases:
Certificates are issued to entities in an organization arrangement by
organizational unit (OU). The OU may be a department, team, or any other logical
grouping of resources with similar roles. The entities within the OU
should be granted the same policies.
```
$ vault write auth/cert/certs/ou-engineering \
certificate=@ca.pem \
policies=engineering \
allowed_organiztaional_units=engineering
$ vault write auth/cert/certs/ou-engineering \
certificate=@ca.pem \
policies=engineering \
allowed_organiztaional_units=engineering,support
```
* auth/aws: Make identity alias configurable
This is inspired by #4178, though not quite exactly what is requested
there. Rather than just use RoleSessionName as the Identity alias, the
full ARN is uses as the Alias. This mitigates against concerns that an
AWS role with an insufficiently secured trust policy could allow an
attacker to generate arbitrary RoleSessionNames in AssumeRole calls to
impersonate anybody in the Identity store that had an alias set up.
By using the full ARN, the owner of the identity store has to explicitly
trust specific AWS roles in specific AWS accounts to generate an
appropriate RoleSessionName to map back to an identity.
Fixes#4178
* Respond to PR feedback
* Remove CreateOperation
Response to PR feedback
Update AWS Auth backend to use TypeHeader for iam request headers
- Remove parseIamRequestHeaders function and test, no longer needed with new TypeHeader
- Update AWS auth login docs
* Consistently use "Google Cloud" where appropriate
* Update GCP docs
This updates the GCP docs to use the new updated fields that will be
present in the next release of the plugin as well as fixes up some
inconsistencies between the GCP docs and other auth method
documentation.
* Update aws auth docs with new semantics
Moving away from implicitly globbed bound_iam_role_arn and
bound_iam_instance_profile_arn variables to make them explicit
* Refactor tests to reduce duplication
auth/aws EC2 login tests had the same flow duplicated a few times, so
refactoring to reduce duplication
* Add tests for aws auth explicit wildcard constraints
* Remove implicit prefix matching from AWS auth backend
In the aws auth backend, bound_iam_role_arn and
bound_iam_instance_profile_arn were ALWAYS prefix matched, and there was
no way to opt out of this implicit prefix matching. This now makes the
implicit prefix matching an explicit opt-in feature by requiring users
to specify a * at the end of an ARN if they want the prefix matching.
