Hi,

- What kind of SSH server are you using?
- Perhaps the file permissions are too liberal on the users .ssh directory or files.
Make sure /home/[user] is only writable by the user and make the /home/[user]/.ssh directory read/write only for the owner.


Check /var/log/auth.log for clues.

Good luck!

I have exchanged public keys in the same manner in all cases. Two users
can successfully logged in with their exchanged public key and no manual
password typing is required. One user, despite the same exchange
manner, continues to be asked for a password on SSH connection.


Knowing that SSH connects with the other two users that function
correctly, I am dumbfounded as to why this one user will not connect
without asking for manual intervention.  I can see that all information,
for each user, is in the same location and indeed present.  But, this
one user will not connect without typing in it's password.

What am I overlooking?
