[Mageia-discuss] password-less ssh

I need password-less ssh between all Linux systems on my LAN. Worked 
great until some weeks (?) ago. Still works for opening sessions from my 
laptop to run on the server. But when the server opens a session on the 
laptop, all at sudden a password is required.

My configuration is slightly complex: my systems are multi-boot with 
several OS-partitions (for instance to ease coexistance between the 
production system and cauldron). To simplify key management, I keep the 
key files in a template-directory in a shared (non-OS) partition, 
replacing the files in $HOME/.ssh by symbolic links to files in that 
directory (and, the server and the laptop are configured as identical as 
possible, in particular, same ssh_config and sshd_config files).

I can make (sounds easy, was quite a loss of time to find out) the 
problem come and go by having $HOME/.ssh/authorized-keys as a link into 
the shared directory (come), or using a copy of the template file (go) - 
as said, the problem only appears on the laptop (and no problem having 
the public and private key files implemented as links). Note: the 
permissions are ok (0600 for the private key file and for authorized keys).

For the user that is a regression - is this a bug to be filed?, is it 
due to some security enhancement and just bad luck?
