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

ypset(8)						      System Manager's Manual							  ypset(8)

NAME
ypset - bind ypbind to a particular NIS server SYNOPSYS
ypset [ -d domain ] [ -h hostname ] server DESCRIPTION
In order to run ypset, ypbind must be initiated with the -ypset or -ypsetme options. See ypbind(8). ypset tells ypbind to get NIS ser- vices for the specified domain from the ypserv(8) process running on server. In cases where several hosts on the local net are supplying NIS services, it is possible for ypbind to rebind to another host even while you attempt to find out if the ypset operation succeeded. For example, you can type: example% ypset host1 example% ypwhich host2 which can be confusing. This is a function of the NIS subsystem's attempt to know always a running NIS server, and occurs when host1 does not respond to ypbind because it is not running ypserv (or is overloaded), and host2, running ypserv, gets the binding. Server indicates the NIS server to bind to, and must be specified as a name or an IP address. This will work only if the node has a cur- rent valid binding for the domain in question, and ypbind has been set to allow use of ypset. In most cases, server should be specified as an IP address. OPTIONS
-d domain Specify a domain other than the default domain as returned by domainname(1). -h hostname Set the NIS binding on host hostname instead of the local machine. SEE ALSO
domainname(8), ypbind(8), ypcat(8), ypmatch(1), ypserv(8), yppoll(8), ypwhich(1) AUTHOR
ypset is part of the yp-tools package, which was written by Thorsten Kukuk <kukuk@suse.de>. YP Tools 2.7 May 1998 ypset(8)
