root SSH OK, personal-user SSH not OK (ssh & authorized_key)

[JayG]

Hello everybody,
I try to authenticate me in SSH (with private/public keys) on me freenas server with a personnal account.

I firstly tried with my root acccount
// On my freenas
# touch /.shh/authorized_keys
# chmod 777 /.shh/authorized_keys
# ssh-keygen
# cat id_rsa.pub >> ~/.ssh/authorized_keys

# cp id_rsa -> clientMachine
ssh connection with private key -> Works !

I created a new user :
Account name : backup
Login shell : sh
Primary group : guest
Secondary group : ftp
Home directory : /home/nas/backup

I firstly did the same thing in root (create a private/public key, add it to authorized_key)
But I can't authenticate me with the private key
I secondly did it with the backup account (connection in ssh to the serveur with backup account and create private/public key with this account) but it doesn't work neither...

Do you know what could be the problem ?
Thank you

I've had problems with ssh keys where the public key had an extra space or wrapped to the next line. Cat your authorized_keys and make sure everything is on one line. also compare the failing key with the root key that works. that's all I can think of... hope it helps
