Has anyone got openssh to work with privilege separation?
I tried today, openssh refused with strange reason:

error: mm_send_fd: sendmsg(4): Invalid argument

strace shows that sendmsg system call returns EINVAL:

sendmsg(5, {msg_name(0)=NULL, msg_iov(1)=[{"\0", 1}], msg_controllen=24, {cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_
type=SCM_RIGHTS, {4, 385875968}}, msg_flags=0}, 0) = -1 EINVAL (Invalid argument)

If needed, I can send full strace log.
