Hi,
On our Alpha 2100 (OSF/1 3.0A) we're about to create nearly 4000 usernames.
The accounts are only used for POP mail access (so login-shell is /bin/false,
no files except mailspool).
In the man page of the adduser script i saw that there is a limit to the
number of users you can put in one group. The limit is set by the variable
LINEMAX in the file limits.h. It takes a kernel rebuild to change
this limit.
My original plan was to put all 4000 usernames in one group but after
reading the above i'm not so sure anymore.
My questions are:
- given the default value of LINEMAX, how many users can be put in one
group ?
- is there an other way to get that many users in one group ?
- because these 4000 usernames are all in only one group (their primary
group !!) is it possible to just leave all these usernames out of
the /etc/group file (since their primary group id is in the /etc/passwd
i don't see the need of putting i also in the /etc/group file, or am
i wrong ?)
