/etc/group

[Dan Am]

What is the max amount of users in a given
group in /etc/group and wher is that documented ?
There seems to be a limit on about 70 .

Hi,

man group says:
The length of each line in /etc/group is limited to LINE_MAX, as defined in . The maximum number of users per group is (LINE_MAX - 50)/9.
All group IDs used in /etc/logingroup or /etc/passwd should be defined in /etc/group. No user should be associated with more than NGROUPS (see setgroups(2)) groups in /etc/logingroup.

I know that thereare limits for members in a group :

"Prior to HP-UX 10.30, SAM alloed groups in /etc/group file whith up to 4000 members to be created. These large groups have never been and are still not fully supported by all of HP-UX, most notably HP-UX commands. The largest group that is fully supported by HP-UX is a group that takes up LINE_MAX (2048) characters for a group definition in the /etc/group file. SAM will still allow groups whith up to 4000 members to be created, but in HP-UX 11 it will discourage this by issuing a warning message before creating or extending a group that is over LINE_MAX characters in size".

Patrice.
