Hi list,
Some time ago I had a FreeBSD 4-10 (planning to upgrade it to DF)
installation for my mail/file server.
The users (about 800) on that box make exstensivly use of groups.
Because I already had the security groups, I thought using those groups
for e-mail aliasing to multiple users would be a good idea. So I set up
a couple of scripts which greps the right groups and creates the mail
aliases in /etc/mail/aliases.
While creating a a couple of new security groups a user became member of
more that 15 groups (18).
So till now nothing went wrong but at the moment that users gets a
e-mail sendmail suddenly can't resolve the users name and keeps the mail
in the que.
After some searching I found that the limit on this system is for users
to not be in more than 16 groups.
Although I could work around the problem I'm still curios how to really
solve it.
Could I just change /usr/src/sys/sys/syslimits.h and rebuild the whole
system including all applications? And would that really work, I presume
that those limits are not for nothing on hard set to 16, what are caveates ?
Thanks for reading.
