Re: changing kern.ngroups

2006-05-24 Thread Valerio daelli


Cool. Any suggestion on what to do if I do want to change it?


We managed to get 64 groups changing these files

/usr/include/sys/syslimits.h
/usr/src/sys/sys/syslimits.h

NGROUPS_MAX from 16 to 64, then recompiling world.
We use NFS and we never had problems (more than one year running).
But I heard you may get some trouble with some hardcoded limits.
Bye

I was just wondering if there is any specific reason it is set so low
and any thing to worry about when bumping it up?


The limit is historical, but various protocols like NFS have the # of 
groups limit embedded into their specifications.  Trying to change this 
limit may result in odd behavior, such as user accounts not being 
recognized as being in their "primary" group, ie the one listed in 
/etc/passwd
