This is ending up being the culprit. You see my home directory is on an 
SMB share. Now I had set CYGWIN to "ntsec smbntsec" in the Windows 
System Environment Variables so that services would see it and I thought 
that that would propogate down to the shells. But alas our /etc/profile 
explicitedly set CYGWIN to just "ntsec". With this setting my bash shell 
could chmod 600 <file> all it wanted to but if <file> was on an SMB 
share it would not change the mod bits! Changing /etc/profile to set 
CYGWIN to "ntsec smbntsec" now allows me to chmod on SMB shares. After 
setting the permissions correclty on the files in ~/.ssh ssh'ing works!

Now on to another problem. Perhaps this can't be done. As the user 
adefaria I wish to ssh to another machine as another user (ccadmin) and 
not be prompted with a password. Is this doable without "giving away the 
farm" security-wise? To allow certain users the right to ssh as another 
user without the need for a password?

Finally, I would like to ssh to my home machine without needing a 
password. At work I'm adefaria, at home I'm Andrew. I wish to

$ hostname
adefaria
$ echo $USER
adefaria
$ ssh Andrew@<home>.com

and have my home machine set up to allow adefaria@adefaria to come in as 
Andrew.
