Login ssh for non root user

I have enable SSH login and Shell Access, after login with SSH the client close the window, i have this log from CWP

Jul 22 22:44:38 mysvr sshd[25780]: Accepted password for *** from *** port *** ssh2
Jul 22 22:44:38 mysvr sshd[25780]: pam_limits(sshd:session): Could not set limit for 'nofile': Operation not permitted
Jul 22 22:44:38 mysvr sshd[25780]: pam_unix(sshd:session): session opened for user **** by (uid=0)
Jul 22 22:44:38 mysvr sshd[25780]: error: PAM: pam_open_session(): Permission denied

Only root user work with ssh, why?

Try to change the open files limit in user configuration.
