I'm not sure whether changing indexing configuration is the right way to
really improve things. Hint: Adding indexes can make search performance
worse.

So you should first carefully analyzes which LDAP search queries are
sent to the LDAP server.

You also did not provide any information about the LDAP-enabled NSS
client used and its configuration (which is better discussed on the
mailing list of that software though).
