-=== Impersonation
-A request to the {product-title} API may include an *Impersonate-User* header,
-which indicates that the requester wants to have the request handled as though
-it came from the specified user. This can be done on the command line by passing
-the `*--as=username*` flag.
-
-Before User A is allowed to impersonate User B, User A is first authenticated.
-Then, an authorization check occurs to ensure that User A is allowed to
-impersonate the user named User B. If User A is requesting to impersonate a
-service account (*system:serviceaccount:namespace:name*), {product-title} checks
-to ensure that User A can impersonate the *serviceaccount* named *name* in
-*namespace*. If the check fails, the request fails with a 403 (Forbidden) error
-code.
-
-By default, project administrators and editors are allowed to impersonate
-service accounts in their namespace. The *sudoers* role allows a user to
-impersonate *system:admin*, which in turn has cluster administrator permissions.
-This grants some protection against typos (but not security) for someone
-administering the cluster. For example, `oc delete nodes --all` would be
-forbidden, but `oc delete nodes --all --as=system:admin` would be allowed. You
-can add a user to that group using `oadm policy add-cluster-role-to-user sudoer
-<username>`.
