If you’re able to get valid user credentials, but you’re unable to login because the password has expired and/or needs to be changed, you can leverage this tool in Kali Linux.

smbpasswd -U <username> -r <domainController>

Note: You can use either the FQDN of the Domain Controller, or it’s IP address.

This tool will prompt you for the current password of the user, along with what password you desire.
