+
+Manage access control lists for network services. There are currently
+two named access control lists, @var{vnc.x509dname} and @var{vnc.username}
+matching on the x509 client certificate distinguished name, and SASL
+username respectively.
+
+@table @option
+@item acl show <aclname>
+list all the match rules in the access control list, and the default
+policy
+@item acl policy <aclname> @code{allow|deny}
+set the default access control list policy, used in the event that
+none of the explicit rules match. The default policy at startup is
+always @code{deny}
+@item acl allow <aclname> <match> [<index>]
+add a match to the access control list, allowing access. The match will
+normally be an exact username or x509 distinguished name, but can
+optionally include wildcard globs. eg @code{*@@EXAMPLE.COM} to allow
+all users in the @code{EXAMPLE.COM} kerberos realm. The match will
+normally be appended to the end of the ACL, but can be inserted
+earlier in the list if the optional @code{index} parameter is supplied.
+@item acl deny <aclname> <match> [<index>]
+add a match to the access control list, denying access. The match will
+normally be an exact username or x509 distinguished name, but can
+optionally include wildcard globs. eg @code{*@@EXAMPLE.COM} to allow
+all users in the @code{EXAMPLE.COM} kerberos realm. The match will
+normally be appended to the end of the ACL, but can be inserted
+earlier in the list if the optional @code{index} parameter is supplied.
+@item acl remove <aclname> <match>
+remove the specified match rule from the access control list.
+@item acl reset <aclname>
+remove all matches from the access control list, and set the default
+policy back to @code{deny}.
