# By default never place cookies if we "detect" NFS. We detect NFS
# by detecting "root-squashing". It seems bad practice to place

# XDMCP is the protocol that allows remote login. If you want to log into
# gdm remotely (I‘d never turn this on on open network, use ssh for such

# or -indirect <thishost> to run a chooser. Look for the ‘Terminal‘ server
# type at the bottom of this config file.

# Distributions: Ship with this off. It is never a safe thing to leave
