I am fully aware of eDirectory. However, just like PAM, OpenLDAP, and other
add-on directory tools, it isn't fully adopted or utilized by all of the
Linux tools. Few if any OpenSource projects have embraced NDS. Maybe I'm
wrong, but I don't believe it would ever be adopted as a standard by the
Linux community.

Your last sentence "Just a bitch to admin" sums it up pretty well.

In my opinion PAM is a hack, and it breaks a compatibly with a lot of stuff
out there. I really don't care what technology is used to get the job done.
But as I said in a earlier post I don't see how DS can become reality unless
there is a standard supported by everyone.

Exactly.

Perhaps the kernel? It depends on how deep DS plays a roll on Linux. With
CAP implemented you can lock down the system so that root can't even perform
some tasks.

What if some less then enthusiastic has semi-mangled a /etc file. Can you
guarantee that the script will correctly parse and modify it? Scripting
works fine if the machines are completely uniform, but I bet you there are a
lot of sysadmins that would be weary of perform a large scale change on
/etc/*.conf files.

I know I am going to get some dirty looks about this, but also consider the
scenerio that a larger company wants to move off of Windows to Linux for the
desktop. To start off most of your desktop support technicians will NOT be
capable of writing scripts to apply changes. With a DS system in place you
can create admin tools that dumb down the configuration. I know some people
will consider this a week argument,but its true. I believe that in order for
Linux to reach the desktop, there has to be a method to manage them easier
than the current available tools. I think DS is the best approach.

Thanks,
Ron
