I have a list of usernames/passwords that were the initial passwords given, but should have been changed. I've been told that some of the users used the same password and we want to make sure the password has been changed. We now have a password policy in place for the group, but how can I check if the password has changed? Please note that users did enter a new password, but because a password policy was not in place at the time, some entered the original password as the new password.
I have a file in the following format of username,password:
How can I test the credentials in this file against AD to see what users entered the same password? I was thinking I would probably use either PowerShell, VBScript, C# or VB.net.
