NTP is not a compulsory part of ApacheDS. ApacheDS has a modular network layer to allow any kind of directory backed protocol to be plugged into it to serve directory data in another protocol like DNS, DHCP, or Kerberos. Now we just wrote an NTP module because (1) it was easy to do so to test the layer along side LDAP and Kerberos (2) Kerberos might need it to synchronize time across ApacheDS instances.

We do have this philosophy for the modules.

It was really easy to do so we did it. Later on it might prove very useful when the Kerberos becomes more popular. -- Best Regards, -- Alex
