-# Authentication and Authorization
-
-This document describes how authentication (authn) and authorization
-(authz) are implemented in Argo CD. There is a clear distinction in
-the code base of when and how these two security concepts are
-enforced.
-
-## Logical layers
-
-The diagram bellow suggests 4 different logical layers (represented by
-4 boxes: HTTP, gRPC, AuthN and AuthZ) inside Argo CD API server that
-collaborate to provide authentication and authorization. 
-
-- **HTTP**: The HTTP layer groups the *logical elements* that
-  collaborate to handle HTTP requests. Every incoming request reaches
-  the same HTTP server at the same port (8080). This server will
-  analyze the request headers and dispatch to the proper internal
-  server: gRPC or standard HTTP.
-
-- **gRPC**: The [gRPC][4] layer groups the logical elements responsible for
-  the gRPC implementation.
-
-- **AuthN**: The AuthN represents the layer responsible for
-  authentication.
-
-- **AuthZ**: The AuthZ represents the layer responsible for
-  authorization.
-
-![Argo CD Architecture](../../assets/argocd-arch-authn-authz.jpg)
-
-## Logical elements
-
-The logical elements (identified by numbers) can represent an object,
-a function or a component in the code base. Note that this particular
-distinction is not represented in the diagram.
-
-Incoming requests can reach Argo CD API server from the web UI as well
-as from the `argocd` CLI. The responsibility of the represented
-elements are described below with their respective numbers:
-
-1. **Cmux**: Uses the [cmux][1] library to provide a connection
-   multiplexer capability making it possible to use the same port to
-   handle standard HTTP as well as gRPC requests. It is responsible
-   for inspecting incoming requests and dispatch to appropriate
-   internal servers. If the request version is `http1.x` it will
-   delegate to the *http mux*. If the request version is `http2` and
-   has the header `content-type: application/grpc`, it will delegate
-   to the *gRPC Server*.
-
-1. **HTTP mux**: A [standard HTTP multiplexer][8] that will handle non
-   gRPC requests. It is responsible for serving a unified [REST
-   API][3] to the web UI exposing all gRPC and non-gRPC services.
-
-1. **gRPC-gateway**: Uses the [grpc-gateway][2] library to translate
-   internal gRPC services and expose them as a [REST API][3]. The
-   great majority of API services in Argo CD are implemented in gRPC.
-   The grpc-gateway makes it possible to access gRPC services from the
-   web UI.
-
-1. **Server**: The internal gRPC Server responsible for handling gRPC
-   requests.
-
-1. **AuthN**: Is responsible for invoking the authentication logic. It
-   is registered as a gRPC interceptor which will automatically
-   trigger for every gRPC request.
-
-1. **Session Manager**: Is the object responsible for managing Argo CD
-   API server session. It provides the functionality to verify the
-   validity of the authentication token provided in the request.
-   Depending on how Argo CD is configured it may or may not delegate
-   to an external AuthN provider to verify the token.
-
-1. **AuthN Provider**: Describes the component that can be plugged in
-   Argo CD API server to provide the authentication functionality such
-   as the login and the token verification process.
-
-1. **Service Method**: represents the method implementing the business
-   logic (core functionality) requested. An example of business logic
-   is: `List Applications`. Service methods are also responsible for
-   invoking the [RBAC][7] enforcement function to validate if the
-   authenticated user has permission to execute this method.
-
-1. **RBAC**: Is a collection of functions to provide the capability to
-   verify if the user has permission to execute a specific action in
-   Argo CD. It does so by validating the incoming request action
-   against predefined [RBAC][7] rules that can be configured in Argo CD
-   API server as well as in Argo CD `Project` CRD.
-
-1. **Casbin**: Uses the [Casbin][5] library to enforce [RBAC][7] rules.
-
-1. **AuthN Middleware**: Is an [HTTP Middleware][6] configured to
-   invoke the logic to verify the token for HTTP services that are not
-   implemented as gRPC and requires authentication.
-
-1. **HTTP Handler**: represents the http handlers responsible for
-   invoking the business logic (core functionality) requested. An
-   example of business logic is: `List Applications`. Http handlers
-   are also responsible for invoking the [RBAC][7] enforcement function to
-   validate if the authenticated user has permission to execute this
-   business logic.

+2. `doesn't match $setElementOrder list: [`

-If you are connecting repositories via SSH, Argo CD will need to know the SSH known hosts public key of the repository servers. You can manage the SSH known hosts data in the ConfigMap named `argocd-ssh-known-hosts-cm`. This ConfigMap contains a single key/value pair, with `ssh_known_hosts` as the key and the actual public keys of the SSH servers as data. As opposed to TLS configuration, the public key(s) of each single repository server Argo CD will connect via SSH must be configured, otherwise the connections to the repository will fail.

+* `argocd-repo-server` Every 3m (by default) Argo CD checks for changes to the app manifests. Argo CD assumes by default that manifests only change when the repo changes, so it caches the generated manifests (for 24h by default). With Kustomize remote bases, or Helm patch releases, the manifests can change even though the repo has not changed. By reducing the cache time, you can get the changes without waiting for 24h. Use `--repo-cache-expiration duration`, and we'd suggest in low volume environments you try '1h'. Bear in mind that this will negate the benefits of caching if set too low.

+## Known Issues
+
+### Broken `project` filter before 2.4.27
+
+Argo CD 2.4.0 introduced a breaking API change, renaming the `project` filter to `projects`.
+
+#### Impact to API clients
+
+A similar issue applies to other API clients which communicate with the Argo CD API server via its REST API. If the
+client uses the `project` field to filter projects, the filter will not be applied. **The failing project filter could 
+have detrimental consequences if, for example, you rely on it to list Applications to be deleted.**
+
+#### Impact to CLI clients
+
+CLI clients older that v2.4.0 rely on client-side filtering and are not impacted by this bug.
+
+#### How to fix the problem
+
+Upgrade to Argo CD >=2.4.27, >=2.5.15, or >=2.6.6. This version of Argo CD will accept both `project` and `projects` as
+valid filters.
