[SunHELP] Group memberships.

By default, Solaris makes new files with the group ownership the same as the
primary group (the GID in /etc/passwd) of the file creator.  If you SUID the
directory, it'll adopt the standard that new files are created with the
group ownership of the parent directory:

Check out this example below...  Using this "feature" may mean the person
has to change is group less.  Making a file in each groups' directory will
make ownership appropriate for that group.  Reading & altering already
created files should require no need to switch groups as the user should
exist in both groups simultaneously.

Hi! I have a user who is a member of two groups. The user accesses/creates
directories and files under both permissions. The user is getting frustrated
with the frequency with which he has to use the newgrp command. Is there a
way
in which he can do his work without having to use the newgrp command so
frequently? Is there a way to set things that the OS recognizes your group
memberships and you are able to work without having to use newgrp to change
your group?

I cannot set world permissions in the areas where the user is working. Also
I
cannot combine the files/dirs into one group since they belong to different
departments.

Thanks a lot.

Regards
Ajit
