* Move configuration from lib/service to lib/service/servicecfg
The new servicecfg package will hold only configuration for services.
This will allow other packages (like tctl and tsh) to depend on
servicecfg without pulling in all of lib/service (which has a number
of platform-specific details).
This is the first step towards being able to build tctl for Windows.
* Move PAM and BPF config into servicecfg
This breaks a compile-time dependency on BPF/PAM for tctl.
* Move the authorizer into its own package.
The Authorizer and associated functions and constants have been moved into
their own package `authz`. This will allow us to more easily create separate
services for gRPC functionality so that we're not pushing as much into the
`lib/auth` package.
Though this PR is large, the only actual code change here is making
`ContextForLocalUser` exported and changing the `permissions_test.go` so that
it doesn't rely on the `lib/auth` package.
* Use context functions.
* Test and linting fixes.
* Add in a temporary alias file to ensure e still compiles.
* Use functions instead of var aliases for performance reasons.
* Adding in godocs, cleaning up tests.
* Fix tests.
* Add a few more aliases.
Added the ability to specify two CLI flags for Access Requests:
"--request-ttl" and "--session-ttl".
Updated "CreateAccessRequest" to adhere to the following rules.
If an Access Request does not have a TTL set (expiration time
types.AccessRequest resource itself), a default of 1 hour is used. Next,
the request value is truncated by the lifetime of the certificate,
requested expiration, and then strictest session TTL on all roles
requested.
Similar logic is followed for the expiration time of the elevated
certificate that will be issued if the Access Request is approved. First
the requested value is truncated by the lifetime of the certificate,
requested expiration, and then strictest session TTL on all roles
requested.
The output of "tsh requests ls" and "tctl requests ls" has been updated
to display the TTL values.
* Add hint message when removing access requests.
* Add hint message if removing an access request that has already been approved.
* fixed typo.
* do not delete access requests unless it hasn't been approved or a force flag has been provided.
* Tweaked hint messaging.
Various improvements related to extending the dynamic access
API, including:
- Support for users with no statically defined roles.
- Unify trait mapping logic (e.g. claims_to_roles) across
the connector types.
- Support for matcher syntax and claims_to_roles mappings when
configuring which roles a user is able to request.
- Allow tsh or the web UI to automatically generate wildcard
access requests when dictated by role configuration.
- Allow RBAC configuration to attach annotations to pending
access requests which can be consumed by plugins.
- Allow plugins to attach annotations to approvals/denials
which appear in the audit log, and may also be looked up
later to determine additional info about a resolution.
- Support prompts, request reasons, and approval/denial
reasons for access requests.
