ssh no-passphrase works for one user, but not another.

Hi,

Trying to set up 'passwordless' logins.  I can get them to work for one user, but not another.  On the same box.
The output from ssh -vvv  (included below) says it can't figure out the key type and doesn't like something about the key format, too much whitespace among other things.  But it works for the other user, using exactly the same sequence.

I'm stumped.  Any hints appreciated.

---------------------------------------------------------------------------

 I'm first attempting on a single box named mm04.

1. Gen the key

mm04$ ssh-keygen -t rsa -C"thomson"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/thomson/.ssh/id_rsa):
Enter passphrase (empty for no passphrase): <cr>
Enter same passphrase again: <cr>
Your identification has been saved in /home/thomson/.ssh/id_rsa.
Your public key has been saved in /home/thomson/.ssh/id_rsa.pub.
The key fingerprint is:
6a:23:1f:c0:5e:60:4f:28:09:87:46:f9:d0:ba:ef:6f thomson

mm04$ ls
id_rsa       id_rsa.pub   known_hosts

2.  do authorized_keys

mm04$ cp id_rsa.pub authorized_keys

3  Now try to do a passwordless ssh to the same machine

mm04$ ssh mm04
The authenticity of host 'mm04 (10.70.1.54)' can't be established.
RSA key fingerprint is e9:64:e6:e4:c8:89:16:60:45:ea:d2:e0:79:bb:1b:a1.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'mm04,10.70.1.54' (RSA) to the list of known hosts.
Last login: Wed Oct  6 18:52:35 2004 from 10.70.1.99

mm04$

Works.  Very kewl.

-------------------------------------

Now to do the next user:

1.  gen the key:

mm04[pspy]> ssh-keygen -t rsa -C"pspy"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/pspy/.ssh/id_rsa):
Enter passphrase (empty for no passphrase): <cr>
Enter same passphrase again: <cr>
Your identification has been saved in /home/pspy/.ssh/id_rsa.
Your public key has been saved in /home/pspy/.ssh/id_rsa.pub.
The key fingerprint is:
39:31:99:ee:92:70:77:a3:c4:8c:c3:cb:ab:2d:71:e1 pspy
mm04[pspy]>

2.  set up authorized_keys:

mm04[pspy]> ls -la
total 18
drwx--l---   2 pspy     spec         512 Oct  6 18:46 ./
drwxrwsr-x  14 pspy     spec        4608 Oct  6 18:43 ../
-rw-------   1 pspy     spec         883 Oct  6 18:44 id_rsa
-rw-r--r--   1 pspy     spec         214 Oct  6 18:44 id_rsa.pub
-rw-r--r--   1 pspy     spec         458 Oct  6 14:41 known_hosts
mm04[pspy]> cp id_rsa.pub authorized_keys
mm04[pspy]>

mm04[pspy]> ls -la
total 20
drwx--l---   2 pspy     spec         512 Oct  6 18:46 ./
drwxrwsr-x  14 pspy     spec        4608 Oct  6 18:47 ../
-rw-r--r--   1 pspy     spec         214 Oct  6 18:46 authorized_keys
-rw-------   1 pspy     spec         883 Oct  6 18:44 id_rsa
-rw-r--r--   1 pspy     spec         214 Oct  6 18:44 id_rsa.pub
-rw-r--r--   1 pspy     spec         458 Oct  6 14:41 known_hosts
mm04[pspy]>

OK, should work now.

mm04[pspy]> ssh mm04
pspy@mm04's password:

Rats.  Still asking for a password.
