[arch-general] About sshfs multi user idmap

Is there a way to map multiple users via sshfs? If I am using connect to a remote host through root, and I want to other user have access to it with allow_other, then, I hope their id could be mapped, ie. local http map to remote http, local user1 map to remote user1, and so on. both of them have the same user id and group id with the remote. How can I accomplish that?
