freeBSD8.2: getgrgid() works only for wheel group.

[Rekhesh Mohan]

Dear Hackers,

I'm trying to install mailman on a freeBSD 8.2 box. Mailman allows only 
the apache-www group to run its CGI scripts and only the mail group can 
execute some of the mailing list related functionalities. Mailman is 
using  getgrgid() to check the group name. This is failing on me.

It appears that only the wheel group members are allowed to use 
getgrgid() on my machine. getgrgid() returns (null) for others. I was 
wondering if anyone else has faced this situation. 

Let me know.. Thanks in advance!
