OpenSSH_3.4p1 and OpenSSH_2.5.2p2

Hi,
We're using OpenSSH_2.5.2p2 on HP_UX 11.x (client side) and trying to connect to a server running OpenSSH_3.4p1 on Red Hat Linux 8.0. I have generated the DSA keys on the client side and transferred the public key to the server but all my attempts to connect using public key authentication have failed. I have successfully used my client to connect to other servers using same keys but those servers are running commercial versions of SSH (FSecure ver. 5.0) on Windows platform.

I experience 2 distinctive problems. First, although the configuration on the server side says that the SSH2 should be used, the connection uses SSH1 and I have to force it to use SSH2 (using -2 option). Second, when it uses SSH2, the public key authentication fails and it resorts to password authentication, which is not desirable.

>From my client side (OpenSSH_2.5.2p2) I can connect to other servers and
even my own server (kind of recursive SSH) successfully using public key authentication but I had no success so far with this one. I played with different configurations like using Authorized_keys and authorized_keys2, id_dsa and id_rsa files, directory permissions and tweaking SSH daemon configuration on the server but nothing has worked so far.

Is there an incompatibility problem between these 2 versions or have I missed something in my configuration that has caused this problem?

Your help and consideration is very much appreciated.
