Questions tagged [windows-identity]

Use this tag to better reference questions about WindowsIdentity allowing to encapsulate information about Windows accounts.

The WindowsIdentity object encapsulates information about Windows accounts. You use the WindowsIdentity object if you want to make authorization decisions based on a user's Windows account information.

For example, using WindowsIdentity and WindowsPrincipal objects, you can write an application that requires all users to be currently validated by a Windows NT or Windows 2000 domain. You can also allow certain domain accounts to access your application while denying access to others.
