A server stack is the collection of software that forms the operational infrastructure on a given machine. In a computing context, a stack is an ordered pile. A server stack is one type of solution stack — an ordered selection of software that makes it possible to complete a particular task. Like in this post about Use Different Usernames for Windows Login and Exchange Email Address was one problem in server stack that need for a solution. Below are some tips in manage your windows server when you find problem about windows, active-directory, windows-server-2008-r2, exchange-2013, .
We have Windows Server environment with Active Directory and Exchange. Exchange is already Integrate with Active Directory and Therefore i have security concern because our user names are public. Email address contain User account name and everyone knows our company user names. I want to use different use name for Exchange and active Directory user login. How can i achieve this?
The User-Principal-Name login username will be the same for both.
This attribute contains the UPN that is an Internet-style login name
for a user based on the Internet standard RFC 822. The UPN is shorter
than the distinguished name and easier to remember. By convention,
this should map to the user email name.
Proxy-Addresses, uppercase value
SMTP indicates the primary SMTP email address which is displayed on outbound mail, e.g.
SMTP:email@example.com, whereas lowercase
smtp:firstname.lastname@example.org indicates an alias, a.k.a. proxy address.
proxyAddresses attribute is available in Attribute Editor tab on Properties dialog of the AD user object. However, in Active Directory Users and Computers, you must have View > Advanced Features enabled to see it.
For company wide changes, refer to Procedures for email address policies in Exchange Server.
You can simply change the UPN to a different format while keeping the primary email IDs as per your current format. Since UPN is the login ID, the email id which is public and UPN which isn’t public, would be different things.
Your username is the actual name of the mailbox on the Exchange server. This name was set by your account administrator when your mailbox was created. It could be in the format of firstname.lastname, or name3, and is unique to your mailbox. For example, if your name is John Smith, your username could be john3 or john.smith.
Your primary email address (in our environment, this is also your User Principal Name, or UPN) is associated with your mailbox username. It will also appear in the From field of the messages others receive from your mailbox. You will be able to receive messages using other email addresses, but not send messages from them.
