Unhappy lamboot problem in LAM/MPI

Hi friends
While executing the command lamboot -v hostfile(hostfile contains the list of hosts to which I want to connect),It requires authentication for different hosts.
After giving the password for a host.I get an error:
ERROR: LAM/MPI unexpectedly received the following on stderr:
Permission denied, please try again.
The command recon -v hostfile is executing perfactly,
but lamboot -v hostfile is troublesome.

we also generate the public/private key pair in /root/.ssh/
Plz anybody suggest me a solution.

This is all which is generating when i execute lamboot -v hostfile
LAM 7.0.6/MPI 2 C++/ROMIO - Indiana University

n-1<3705> ssi:boot:base:linear: booting n0 (HOST)
n-1<3705> ssi:boot:base:linear: booting n1 ('s password:'s password: ERROR: LAM/MPI unexpectedly received the fo llowing on stderr:
Permission denied, please try again.'s password: Permission denied, please try again.

Doesn't sound like your passwordless authentication is working. Did you remember to copy the public key to all of the authorized_keys files on the nodes?
