what is happening when you try to login with that user?

What is the entry in /etc/passwd fro newuser?

Is there anything in /etc/profile or /.profile in new user home directory?

hth.

sir,

I just tried to login with new user via telnet and success.but this new user can not login via
ssh protocol.

Can you try as,

ssh -vvv newusername@hostname

what you are getting there.

what you are getting from /etc/passwd for newuser?

grep 'newusername' /etc/passwd

hth.

what's the primairy group of the newuser?
In /etc/opt/ssh/sshd_config we use the line
AllowGroups
to allow users on their primairy group.
make sure the primairy group of the newuser is in there...

hope this helps

have you tried

ssh -l login_name system_name

to ssh use the correct user name?

all,

many thanks for your reply.
I just already solved this problem by myself. but i don't know why it's happened. when i restart ssh daemon, new user can login to my system.:)
anyone know why ??

dears,

something nasty with my system. I just tried to create new user again with user id test. this user can't login via ssh.

# ssh test@localhost
