Dear Group,
I'm having a problem connecting Solaris 10 Server to a Redhat Enterprise
Linux 5.4 and meanwhile pretty clueless on that issue. Hopefully I get
at least a hint, from your group, where to look at.

key-length is 2048, permissions are correct on .ssh-directory and the
files itself, keygen is done manually. On the Linuxserver we're using
openssh-4.3p2-36.el5, on Solaris the standard pkg which comes in Solaris
10/07 and all packages are installed correct. keys are the
same on all servers. Same construct works perfect with other Servers.
Real server-names are changed in following debug-output:
