Unable to ssh to remote server

Hi,

I have two SunOs sparc servers mac1 and mac2.

I have exchanged keys between them inorder to passwordless login ssh from mac1 to mac2.

However, it is failing after authentication.

Part of the debug is as below. Please suggest whats wrong and how do i fix that!! Note: i do not have root credentials.

debug1: Authentication succeeded (publickey).

You need to talk to your system administrator and get permission to do a network login.
