Advantages of using jcifs library over mod_ntlm module

Hi

I am using jcifs for implementing Single Sign On for an intranet application

This works fine, however I need to document a couple of reasons as to why I am using the jcifs librayr over the apache module. I have seen some previous postings relating to jcifs scaling better than the apache module. Just wondering if anybody could provide a few more benefits as to using jcifs over the apache mod_ntml module

Thanks
Joe
