SSH Differences between Solaris 9 and Solaris 10

Question

I use public key authentication when connecting via SSH but have noticed a difference between Solaris 9 and Solaris 10 and wondered if it's an environment setup issue. I keep my keys in $HOME/.ssh
When connecting from Solaris 9 I can provide an identity file without a path regardless of the directory that I'm in e.g.
ssh -i my_identity_file user@hostnameThe above works even if I'm not in the $HOME/.ssh directory. But when using the same from Solaris 10 I get the following error:
Warning: Identity file my_identity_file does not exist.If I run the command from $HOME/.ssh on Solaris 10 it connects fine, and if I pass in the path like so it works fine:
ssh -i $HOME/.ssh/my_identity_file user@hostnameIs there a setting specific to SSH somewhere as I can't see anything in my environment that's different between the two systems. There's certainly no entry in $PATH that points to $HOME/.ssh. How could I get SSH to work on Solaris 10 by just providing the identity file name and not the full path

Answer 1

It's not explicitly defined in /etc/ssh/ssh_config, so I'm assuming it would be using the default which is ~/.ssh/id_dsa.
But surely that's irrelevant if I'm using the -i switch to provide the identity file?
Remember the problem here is that I have to provide a full path to the identity file, whereas before just the filename would do.
