Cannot login using WINBIND in AIX 5.3

I configured AIX5.3 to use kerberos and winbind so user can login and authenticate via AD. I was able to join my AIX server to domain and can execute wbinfo -u/g. However when I login, It says unknown user. I already edit /etc/secuirty/user and then method.cfg.

On the log.winbindd it says
