OpenLDAP id map problem on client machine

[webappl]

I have installed OpenLDAP and shared the ldap user home directory through NFS. On a OpenLDAP client machine, running 'id' command returns the correct user id and group information for a ldap user. However, using 'ls -l' to check the details of ldap user's files failed to map to the correct id and group. Eg, I got nobody and nogroup for a txt file

-rw-r--r-- 1 nobody nogroup 4 Oct 26 14:58 test.txt

How to solve this id mapping problem here?

Thanks,

Alex

Edit file /etc/idmapd.conf on the client by setting the option Domain with the domain name of the server, such as
Domain = example.com

Restart idmapd service and then re-mount the nfs shared folder
sudo service idmapd restart
sudo umount /shared/directory
sudo mount /shared/directory
