LDAP server - nsslapd-maxdescriptors problem

I have created Directory server and suffix for the same in LDAP server. when i am trying to import the ldif files, got failed.
I found in google and trying to change the file nsslapd-maxdescriptors size in dse.ldif file and restarted the server. again it is giving the error as below.

The OS setting for maxdescriptors is still set to the default 1024 based on the message your getting. " invalid value 65536, maximum file descriptors must range from 1 to 1024 (the current process limit) ". You need root access to update the NDD parameter for filediescriptors at the OS level to be higher than the 65536 your trying to set for the Directory. I run a Directory with over 3 million entries and 10,000 connections per hour and I only run 4096 for the directory connections and set idle connection timeout to 1 hour. Unless you have a very very busy Directory 4096 should be good enough.
