 Kevin,
 
 I saw this report and 78087 which looks similar and thought they looked curious.
 
 I have tried to duplicate this issue without luck and am running 
 
 FreeBSD 5.3-RELEASE-p2
 
 bash-2.05b$ sysctl kern.ngroups
 kern.ngroups: 16
 
 relevant portion of /etc/group
 --- snip ---
 foouser:*:1004:
 foo1:*:20001:foouser
 foo2:*:20002:foouser
 foo3:*:20003:foouser
 foo4:*:20004:foouser
 foo5:*:20005:foouser
 foo6:*:20006:foouser
 foo7:*:20007:foouser

 20012(foo12), 20013(foo13), 20014(foo14)
 
 When I uncomment the line '#foo15:*:20015:foouser' from /etc/group
 I get the following error
 
 bash-2.05b$ su foouser
 Password:
 su: setusercontext: Invalid argument
 
 My results are different from yours, but also seem like a bug.  I am
 only able to be assigned to 15 groups despite kern.ngroups being equal
 to 16?   What is kern.ngroups set at for you?
 
 Cheers,
 Russ
