my home directory is in AFS, AFS doesn't permit the creation of sockets

That well deserves an entry on the troubleshooting guide, thank you for posting it back!

which I don't understand since if .libnet-openssh-perl prohibits others from writing to the directory, what good forcing all ancestors to also prohibit writing to their directory gains

For instance, it allows the owner of the upper directory to get Net::OpenSSH placing the mux socket in a file system under its control (for instance a NFS share from other machine where he is root and can change permisions at will), or a specially crafted FUSE-based file system.

Also, he could replace the mux socket by one under his control. That would allow him to see everything you send to the remote machine.

Anyway, I prefer to play on the safe side even if that means being a little paranoid!
