First you must add your linux in to a windows AD, once it is done, login as root or user that is in wheel group.
Execute this command visudo, that will open etc/sudoers file. if you do vi /etc/sudoers vi will give you an permission error. So besure to use visudo without space.
Find a line that looks like this
%wheel ALL=(ALL) ALL
put this just below that like (Yes with \\, in linux \ is an escape charator, so we have to put two \ instead of one \) this...
domain\\username ALL=(ALL)
example: If you want to add a user test1 who is in world.com
world\\test1 ALL=(ALL)
and this is an option you can put just behind the line, so it will not ask for a password if you do sudo. a bit of security issue but if you built a test linux machine gotta do lots of sudo, ye it can be your best friend.
NOPASSWD: ALL
example: world\\test1 ALL=(ALL) NOPASSWD: ALL
That is all.

Installing Exchange 2013 preview - quick and dirty
What you will need, a domain controller, a windows server 2008 or R2 or 2012 and some pre-req items
I will use an Windows 2008 R2 x64 Enterprise version for this demo.
Download a Exchange server 2013 preview from here : http://www.microsoft.com/exchange/en-us/exchange-preview.aspx
All Exchange 2010 servers in the organization need to be at Exchange 2010 SP3 orlater, and SP3 is not available at this time (2012, July), so if you try to install it on the current Exchange 2010, you won't be able to install it at all.

Import-Module ServerManager
Add-WindowsFeature RSAT-ADDS

Put the dvd in to the cdrom, and we need to mount the dvd.
#mkdir /media/CentOS_6.2_Final
after that mount the dvd with this command:
#mount /dev/cdrom /media/CentOS_6.2_Final
and then Edit CentOS-Media.repo
vi /etc/yum.repos.d/CentOS-Media.repo
You will see something like this
baseurl=file:///media/CenOS/
and blah blah
Change the "file=:///media/CentOS" to "file=:///media/CentOS_6.2_Final"
Save the file
and install package
yum --disablerepo=\* --enablerepo=c6-media
for example to install perl
yum --disablerepo=\* --enablerepo=c6-media install perl
#mkdir /media/CentOS_6.2_Final
