SSH prompts password for non identical users

host1 & host2 : Solaris 10 - SPARC server


From host1 able to ssh to host2 as same user with out password prompt. But, when ssh to different user in

host2, it prompts for password

DETAILS
=======

In host1:

1) logged as root
2) ssh-keygen -t dsa -b 1024 (no pass phrase)
3) Ensured that permission for /.ssh is 700 & for id_dsa is 600
4) copied id_dsa.pub to host2 : /.ssh

In host2:

1) logged as root
2) cp /.ssh/id_dsa.pub /.ssh/authorized_keys
3) Ensured that permission for /.ssh is 700 & for authorized_keys is 644


From host1:

1) Login as root
2) ssh host2 - Successfully logs in with OUT asking for the password


In host2

1) created a new userid - abcd - homedir /opt/abcd
2) created /opt/abcd/.ssh - 700
3) copied /.ssh/authorized_keys to /opt/abcd/.ssh/authorized_keys 644


From host1:

1) Login as root
2) ssh abcd@host2 - prompts for password.

What should be done so that, from host1, I can ssh for any user in host2 without getting the password prompt

SSH-COPY-ID(1)						    BSD General Commands Manual 					    SSH-COPY-ID(1)

NAME
ssh-copy-id -- copy public keys to a remote host SYNOPSIS
ssh-copy-id [-lv] [-i keyfile] [-o option] [-p port] [user@]hostname DESCRIPTION
The ssh-copy-id utility copies public keys to a remote host's ~/.ssh/authorized_keys file (creating the file and directory, if required). The following options are available: -i file Copy the public key contained in file. This option can be specified multiple times and can be combined with the -l option. If a private key is specified and a public key is found then the public key will be used. -l Copy the keys currently held by ssh-agent(1). This is the default if the -i option was not specified. -o ssh-option Pass this option directly to ssh(1). This option can be specified multiple times. -p port Connect to the specified port on the remote host instead of the default. -v Pass -v to ssh(1). The remaining arguments are a list of remote hosts to connect to, each one optionally qualified by a user name. EXIT STATUS
The ssh-copy-id utility exits 0 on success, and >0 if an error occurs. EXAMPLES
To send a specific key to multiple hosts: $ ssh-copy-id -i /path/to/keyfile.pub user@host1 user@host2 user@host3 HISTORY
The ssh-copy-id utility was written by Eitan Adler <eadler@FreeBSD.org> as a drop-in replacement for an existing utility included with OpenSSH. BSD
