ssh-keygen problem

[Ron Eggler]

Hi,

We're using Dropbear 0.48
What i did:
I downloaded "openssh-4.6p1.tar.gz" and compiled it on a different system than 
the target system. I wasn't able to compile a more recent version since it 
wouldn't find openSSL even tho it is installed (0.9.8 - I tried to pass the 
correct path with --with-ssl-dir but it wouldn't work). 
Anyways, I got ssh compiled, I copied the "ssh-keygen" binary onto our
target (pc 104, geode) system from where I issued "ssh-keygen -N '' -t dsa -f 
file" it to create a public key
pair, I copied the pub part into the authorized_keys file on our server
(OpenSSH_4.3p2, OpenSSL 0.9.7i 14 Oct 2005) but it wouldn't let the client
in with out a password, why not??? I'm stuck, I have no idea what's going
on. I can get in from a system NOT using Dropbear so the permissions 
of /root/.ssh and all above/below should be set right, i also can't see any 
messages in /var/log/messages. I can cat the authorized_keys file and it 
looks all good.... :o
Any hints on this? Is there some version conflict going on or something?

Thanks alot!
Ron
