Here's something. Following up a suspicion, I entered from root (which, by the way, I've had no difficulty ssh'ing into):
setenforce 0 Everything instantly starting working on /home. I can now do a passwordless login, run X apps remotely (which previously were giving xauth locking errors), and, at least on a minute's examination, it appears fixed. I'm an selinux ignoramus and on earlier rhel versions I just relied on tcp wrappers and shut off selinux completely. I want to use it now. The only tweaks which I think I've made were to follow the instructions in smb.conf to use chcon and setsebool, and to enable samba and tftp in the System Preferences Firewall dropdown. What config file for selinux can I look at, looking for what sort of problem?
