Get-DomainUser Not Filtering on "Name" Argument

[andrewchiles]

Running Get-DomainUser with the following syntax fails to properly filter on the specified username and instead returns all users in the domain. The result was the same despite specifying -name domadmin, -identity domadmin, or simply Get-DomainUser domadmin
