AIX: Could not login using NIS Account?

Hi there,

I am new to AIX environment, when I set up NIS Client for an AIX 5.3 Machine to connect to a Linux NIS Master, everything seems to be okie:

/etc/passwd: +::0:0:::
/etc/group: +:
ps -ef | egrep "ypbind": /usr/lib/netsvc/yp/ypbind -ypsetme -ypsetme

I can get all account information from NIS Master using ypcat

When I was logging in using NIS account, the machine denied and here is what I got from the secure log:

"failed login attempt for UNKNOWN_USER from ..."

Other AIX 5.3 machines on the same domain works ok.

please give me some advices, thanks in advance

NAME
dxaccounts - Graphical interface for account administration SYNOPSIS
/usr/bin/X11/dxaccounts DESCRIPTION
The Account Manager application, dxaccounts, helps you manage user accounts on your Tru64 UNIX system. It operates on both base security level systems and enhanced security (C2) level systems. The Account Manager application lets you manage both the local and Network Information Service (NIS) UNIX account databases. NIS is used in order to centrally manage user accounts in a network environment. NIS lets participating systems share a common set of passwd and group files. NIS uses a client-server model. When the Advanced Server for Tru64 UNIX product is installed, the Account Manager application allows you to perform domain user account management for PC users. To start Account Manager from the CDE desktop:Choose the Application Manager from the CDE front panel. Choose the System_Admin group. Choose the DailyAdmin group. Click on the Account Manager icon. Online help is available for the dxaccounts application. To get help, click on any Help button or use the Help pull-down menu. Account Manager replaces the XSysAdmin(8) and XIsso(8) applications. RESTRICTIONS
You must have root privileges to modify system files with this application. If dxaccounts is run without root permission, you may view but not modify account information. In order to make changes to the NIS databases, you must run Account Manager on the machine designated as the NIS server. FILES
