>Description:
If more than 80 users are in one group, than user lose their group's  belonging 

#grep user /etc/group
trustuser:*:65550:user,user2,user3..... user81

#id user
uid=1010(user) gid=1010(user) groups=1010(user)

If there is less than 80 users, than Ok 

#grep user /etc/group
trustuser:*:65550:user,user2,user3..... user79

#id user
uid=1010(user) gid=1010(user) groups=1010(user), 65550(trustuser)

There is no such problem on FreeBSD 4.11, only in 5.4
