Subject: RE: SSH on Cygwin Immediate Drops Connections
On server 2003 I had to add the sshd user into the Administrators group
to allow auto logon, the -r option did not work.

Big side effect, with auto logon, the user logging in does not have
their domain groups because sshd can not impersonate them like it could
on w2k, so you will have to fiddle with group permissions.

This had the effect that I could not access my tape drive because I am
normally a domain admin, but when I logged into via ssh with authorized
keys, I was no longer a domain admin.

Logging in with keyboard password did not have this problem.

Same thing happens with public key authentication.
