RE: [SunHELP] Group memberships.Hi! Thanks a lot. Setting the group bit on the
directory was the key.

  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
