While performing a Pen test for a client i needed to catch a domain user name and password, there are several ways to gain users passwords and it really depends on a lot of factors on how to get it in my case i didn't had time to wait for the user to enter his credentials and get it using a key logger so I and @Roni_Bachar created a fake windows domain login window to tried to force and trick the user to enter his password.
There are several tools and techniques such as "Mimikatz" but they require you to have administrative/system privileges, you don't need special privileges to execute "Windows Domain Credentials Phishing Tool".
