IIRC it is supported.

For SOCK_DGRAM sockets:
----------------------
[...]
 3: Sending cmsgcred, receiving sockcred

    Server creates datagram socket and set socket option LOCAL_CREDS
    for it.  Client sends one message with data and control message with
    SOCK_CREDS type to Server.  Server should receive one message with
    data and control message with SCM_CREDS type followed by struct
    sockcred{} and this structure should contain correct information.
