# Module Rpc_auth_local

    module Rpc_auth_local: sig .. end

    val server_auth_method : unit -> Rpc_server.auth_method

Return the authentication method `AUTH_LOCAL`.

Note that you need another authentication method that operates at message level (like AUTH_NONE, AUTH_SYS, AUTH_DH), otherwise you will get an error `Auth_too_weak`. `AUTH_LOCAL` overrides the result of the other authentication method.

    val get_peer_credentials : Unix.file_descr -> int * int

Return the pair (euid,egid) for a Unix domain socket. The function raises `Invalid_argument` if it is not available for this operating system. (Generally, this should work on Linux, BSD, and Solaris, and OS with compatible system functions - supported methods are `SO_PEERCRED`, `getpeerucred`, and `getpeereid`).

Some OS support this only for named Unix domain sockets but not for socketpairs.
