Good call... do it... do it now... and don't pass "Go" until you've done it, ya hear me?!

PS: Good luck Smilie

Apologies for late reply, I was away from work for a week.
I have trashed the user and recreated it on the RH box. Same result though.
@vgersh99, I have modified permissions as well.

I did it step by step as you did it, Scott. I'm going to keep playing around with this, I need to get it right.

Ok so I've picked this up again after having to attend to more urgent matters. For testing purposes I set up two VM's on my laptop. One is running RHEL 6 and the other is running Solaris 10. Both for x86 platform.
I can successfully set up key pairs between the two VM's using the methods mentioned in this thread. (Log in without password from Redhat machine to the Solaris machine).
I then tried to set up a key pair between my Redhat VM and the Solaris server I'm actually trying to get it working on and it doesn't work. So that's two different versions of Redhat that doesn't work but it works from the Redhat VM to the Solaris (latest version 10 x86) VM.
I noticed that the ssh package versions are slightly different between the two Solaris instances. I can't however get that version because the server is running on the SPARC platform and already has the latest ssh package for version 10.
If there are any more ideas out there feel free to comment. Just putting it out there Smilie

From the user who you're setting up passwordless, can you paste the output of:

Code:
ssh -vvv user@host

That'll tell us where it's going wrong.

My money's (but i've always been a rotten gambler!) on this idea:

ssh checks perms on the files under ~/.ssh, e.g. if ~/.ssh/id_rsa is anything other than chmod 400 it rubber ear's the file :-)

To give you some hope - if i had £1 for every time i've set this up for production i wouldn't need to work anymore.

There can be loads of small bumps in the road with this - things like keon with dodgy LATs running on the remote host or business groups with policy's that mean AuthorizedKeysFile location is set elsewhere than ~/.ssh/authorized_keys on the remote host. Fun fun fun! :-)

The .ssh/id_rsa didn't match the id_rsa.pub appended to the authorized_keys file on the far side.

The key on the near side appears to be ok (it complains if the key isn't in either OpenSSH or SECSH format).

So the issue isn't on the client, it's on the server. Noone's overridden the AuthorizedKeysFile location in /etc/ssh/sshd_config from the default ~/.ssh/aut...?

Luckily the sshd also support's this -vvv trick:

Code:
root$ sshd -D -vvv -p2222

This will launch a seperate sshd (so if you login to the server via ssh it wont affect your connection on port 22), it keeps the sshd in the foreground, with verbose output, listening on port 2222.

To connect from the client side:

Code:
client$ ssh -p2222 host

The output on the server side will clear up for us why it believes the keys don't match.
