SSH authentication

["Jerry Feldman-2" <user=4@nabble.blu.org>]

 I've got 5 systems in the office all sharing the same /home file 
system.  A while back I set up some ssh keys so I could authenticate 
without the need to type my password. I placed the public key in 
~/.ssh/authorized-keys as well as in my home system, and the 2 BLU 
systems.  At some point a few weeks ago, the public authentication 
stopped working, but only when I log into the local servers. I can log 
into my home system, my Linux laptop as well as the blu servers from my 
local servers using public key authentication.  There are 3 scenarios 
where key authentication does not work and I must use my password: 
1. log in from one Linux system to another Linux system. 
2. log in from my company Windows laptop using a key generated by 
Putty. 
3. log in from my Linux laptop. Again, I can successfully log in from 
my laptop to home or the blu servers. 

The servers are all running RHEL 4 Update 3 (not sure of the patch 
level - these were set up from corporate supplied CDs). The permissions 
of my .ssh directory is 0700 as is id_dsa. A few years ago I had a 
similar problem with one of the BLU severs. 

In my case here, there were no changes made to ssh or sshd.
