Id command does not return correct username

On server1 the "id" command works fine and returns "myuser" user as was expected. Below are the details of the good server.

Code:

$ id -nu 501
myuser

$ cat /etc/system-release
Red Hat Enterprise Linux Server release 7.6 (Maipo)

$ uname -a
Linux server1 3.10.0-957.el7.x86_64 #1 SMP Thu Oct 4 20:48:51 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

$ id
uid=501(myuser) gid=501(was) groups=501(was),1005(coluser)

$ cat /etc/passwd | grep myuser
myuser:x:501:501::/home/myuser:/bin/bash

$ cat /etc/passwd | grep 501
myuser:x:501:501::/home/myuser:/bin/bash

However on server2 the command does not return myuser user as was expected. Below are the details of the problematic server.

Code:

$  id -nu 501
id: 501: No such user

$ cat /etc/system-release
Red Hat Enterprise Linux Server release 6.10 (Santiago)

$ uname -a
Linux server2 2.6.32-754.23.1.el6.x86_64 #1 SMP Tue Sep 17 09:46:55 EDT 2019 x86_64 x86_64 x86_64 GNU/Linux

$ id
uid=501(myuser) gid=501(staff) groups=501(staff),507(coluser)
 
$ cat /etc/passwd | grep myuser
myuser:x:501:501::/home/wlsadmin:/bin/bash

$ cat /etc/passwd | grep 501
myuser:x:501:501::/home/wlsadmin:/bin/bash
myadmin:x:502:501::/home/myadmin:/bin/bash

Can you please suggest how can I get id -nu 501 to display myuser user on problematic server2 ?

NAME

     dsmemberutil -- various operations for the membership APIs, including state dump, check memberships, UUIDs, etc.

SYNOPSIS

     dsmemberutil [-v] [-h] command [options]

DESCRIPTION

     dsmemberutil is a program that implements the membership API calls in a command line utility.

FLAGS

     A list of flags and their descriptions:

     -h      Lists the options for calling dsmemberutil

     -v      Causes dsmemberutil to operate in verbose mode.

COMMANDS

     The action of each command is described below:

     getuuid -ugUGsS value
		 Takes any of the options and returns the associated UUID.

     getid -UGsSX value
		 Takes any of the options and returns the associated UID or GID depending on option provided.

     getsid -ugUGX value
		 Takes any of the options and returns the associated SID.

     checkmembership -uUxs param -gGXS param
		 Returns if a user or group with the associated option is a member of the group.

     flushcache  Flushes the current membership cache.

     Legacy commands such as dumpstate and statistics are gone. See odutil(1) for show cache and statistics operations.

     A list of options available. In some cases -xX and -sS can be used synonymously due to nature of the value.

     -u uid	      Using user with UID

     -U name	      Using user with name

     -s sid	      Using user with SID

     -x uuid	      Using user with UUID

		    EEA4F2F6-B268-49E7-9C6F-E3C4A37DA4FD

     Get a group's uuid
		    % dsmemberutil getuuid -g 0
		    ABCDEFAB-CDEF-ABCD-EFAB-CDEF00000000

		    % dsmemberutil getid -X ABCDEFAB-CDEF-ABCD-EFAB-CDEF0000000C
		    gid: 12

     Check a user's membership in a group (using UID and GID)
		    % dsmemberutil checkmembership -u 501 -g 0
		    user is not a member of the group

     Check a user's membership in a group (using names)
		    % dsmemberutil checkmembership -U root -G wheel
