Notes:

About half the consulting cost of this installation was spent to train on-site
personnel and script/automate/iconize administration tasks. This removes most of
the extremely steep learning curve necessary to administer and maintain current
Open Source solutions. This also helps to make Open Source a viable solution
for organizations that lack experience with Linux and it's applications.
Open Source solutions in their raw form are often very ugly (though quite functional).


Adding Linux servers to an Active Directory network is getting easier everyday.
The release of Samba 3.x now allows organizations to use Linux File Servers in their
Active Directory networks.
