my original query:
when I update the /etc/group file on my NIS server and type
make in /var/yp to update all the other NIS clients the information
is rarely passed correctly. "groups user" gives a different result
than "groups" when run by a given "user". SOMETIMES IT WORKS FINE!
but other times it's a no-go.
the solution: push the netid map whenever you push the group file.
make sure you don't simply run "make" in /var/yp but rather
" make group netid ". Also, the change doesn't become effective
until the user re-logs in.
extra notes: the original shell won't show a change in the group info
because the group membership is determined at first login. The
"groups username" worked always because it uses a system call "getgroups"
instead of using what was determined at login time. One person suggested
running ypinit on both master and slave servers after any group
modification. This *does* work, but is not nessesary.
thanx to all.
