I have not added any IP rules or firewalls for the clients. There is nothing in my system that would restrict an IP. I am sure that the ldap query is not blocked, because in that case 'ldapsearch' or 'getent passwd' would not have shown me the ldap users. What is the selinux difference that I need to check, is there any config files for that?

The /var/log/secure shows authentication failed for invalid user error when I try to ssh using the ldap users. There is no other errors in the logs.

Look for selinux differences between the machines.

Make sure that something about your query isn't limiting logins to
specific IP addresses (and your non-working client is outside of that
IP address list).

Any errors in /var/log/secure or wherever complaints woudl be getting logged?
