Changing maximum number of groups in FBSD - is it feasible?

[Ian Moore]

Hi,

I'm toying with the idea of increasing the maximum number of groups a user can 
belong to on one of my servers - we have a rather complex organisation and 
we're hitting the 15 group limit for some people.

There seems to be differing opinions on how to do this and if it's actually 
feasible. One post I found said:

> in src/sys/sys/syslimits.h there is a constant named 'NGROUPS_MAX'. 
> change it to however many you need (within reason), rebuild/install world 
> and kernel. 

Another said you have to change all sorts of things in the source, modify a 
kernel parameter, rebuild world and rebuild any port that uses NGROUPS - 
which probably means a portupgrade -fa.

There is talk of a maxgroups() parameter in the kernel, but NOTES makes no 
mention of this.

I wonder too if some apps would need their own configuration altered to allow 
them to work with the higher limit.

So I just wanted to ask if anyone has successfully raised the NGROUPS_MAX 
limit, especially when running samba & nfs on the system?

If not, I'll work around the problem a different way.

(BTW I'm running 5.4-RELEASE)

Cheers,
