group file limits

[jonathan]

Hi, I'm running a freebsd 4.8 data server on an intranet.

There is many group (10 and more will come) and a lot of members (10-12 by group) into them... So i'm having big trouble with the fact that 'pw' doesn't read further than 1024 characters into the '/etc/group' file. 

Is there a way to bypass that limit?

Or a better way of managing many groups on freebsd?

I really need to solve this... any help will be a miracle!
