No.
The steps i have followed are
1) generated the key with "ssh-keygen -b 2048 -t rsa" in the client machine
2)public key was added in the servers authorized_keys file.
3) tried to connect to the system with ssh user@host
4) then the system throws an error "Permission denied (publickey,keyboard-interactive)."
But with the same server i have setup another public private key pairing for another user say user1 couple of weeks back. which is working fine . So could you tell me what can be the reason with this user. ?

# dropbearkey -y -f id_rsa | grep "^ssh-rsa " >> authorized_keys
