allowing only certain users to log into Linux boxen

[Alan McKay]

Hey folks,

I finally have this thing running - and I love it so far!  I have
basic Linux login working, as well as Apache auth.  Those are my 2
primary concerns so I think I'm ready to start to roll this bad boy
out.

And one password to unite them all!!!  Bwa, ha, ha, ha!

Anyway, I digress :-)

I checked in here

http://directory.fedoraproject.org/wiki/Documentation#Howtos

and do not see a recipe for what I want to do.  However, when I read
through the Red Hat guides it looks to me like this is possible.  I'm
just not sure how to do it.

I want to have a Group A and Server X, and a rule that says "Only
people from Group A can log into Server X".

And of course the intent is that who is in Group A could change on a
day to day basis (I'm thinking - access to our production environment)

Where can I find a recipe for that?

thanks!
-Alan

Take a look at http://directory.fedoraproject.org/wiki/Howto:Netgroups 
and http://directory.fedoraproject.org/wiki/Howto:Posix

that has nothing to do with ldap, is standard posix. once you have all
users and groups running you have to edit

/etc/security/access.conf

and allow only users you want.

my advice is create a group for every server/environment so you can go
as finer as you want.

then you just have to update group information.

i usually create groups with a prefix:

server-frontweb: user1, user2
server-database: user3, user4

so it's easier to manage.
