Sdm is an x11 display manager similar to xdm, gdm and kdm, but unlike those it wraps the x11 traffic within an ssh tunnel to provide a secure login mechanism for remote x sessions. sdm provides access only through ssh, not locally. it is technically possible to access an sdm server from same host, but probably a waste of cpu power.

this package contains helper files for a terminal to connect to an sdm server, and should be installed on any computer accessing an sdm server.
