Is there a Windows command line utility to verify user credentials?
Solution 1:
You could use the net use
command, specifying the username and password on the command-line (in the form net use \\unc\path /user:username password
and check the errorlevel
returned to verify if a credential is valid.
The runas
command would work, too, except that you're going to have a tougher time testing the output.
Testing a credential for the existence of an account would be a matter of using net user
or dsquery
. The net user
command won't tell you if an account is locked out, but querying the lockoutTime
attribute of the user account could tell you that.
Solution 2:
In Powershell:
Function Test-ADAuthentication {
param($username,$password)
(new-object directoryservices.directoryentry "",$username,$password).psbase.name -ne $null
}
PS C:\> Test-ADAuthentication "dom\myusername" "mypassword"
True
PS C:\>
