Ldap what is samaccountname

A UPN can be assigned, but is not required, when a user account is created. When a UPN is created, it is unaffected by changes to other attributes of the user object such as the user being renamed or moved. This allows the user to keep the same login name if a directory is restructured. However, an administrator can change a UPN. When you create a new user object, you should check the local domain and the global catalog for the proposed name to ensure it does not already exist.

When a user uses a UPN to log on to a domain, the UPN is validated by searching the local domain and then the global catalog. If the UPN is not found in the global catalog, the logon attempt fails. The objectGUID attribute is the unique identifier of a user.

Because an object's distinguished name changes if the object is renamed or moved, the distinguished name is not a reliable identifier of an object. The logon name must be 20 or fewer characters and be unique among all security principal objects within the domain. The objectSid attribute is the security identifier SID of the user.

The SID is used by the system to identify a user and their group memberships during interactions with Windows security. The attribute is single-valued. The SID is a unique binary value used to identify the user as a security principal. The SID is set by the system when the user is created. However, in today's Azure Active Directory-synchronized world, you need to have an internal domain name that matches the business domain you verified in your Azure AD tenant. I show you the interface in the figure below.

You now can update the User logon name property for your affected domain users, either in the user's Properties sheet in Active Directory Users and Computers shown in the next figure , or by using some PowerShell, as in the following example. In the next code block, we start by retrieving a list of our Active Directory users and their current UPNs. We then change their original 4sysops. If you've been following me thus far, we are now aware that since Active Directory Domain Services has been released, our domain users have two sign-in names:.

In summary, I'd like you to walk away from this tutorial with three primary conclusions: Subscribe to 4sysops newsletter! Train your users to sign into the local domain by using what they think is their email address but what is actually their UPN, as you now understand. Accept the inconsistencies introduced with the sAMAccountName attribute. Unless Microsoft redoes Windows internal plumbing, those dependencies are likely to persist indefinitely.
