How to get user password expiration from Active Directory?

Question

people!

There is an Active Directory (Windows) and a Samba Linux client. In Active Directory, the policy has been adjusted so that users periodically change their passwords (passwords have an expiration date).

My question is pretty simple: can I get this expiration time for a given user if I work on a Linux machine with Samba?

Answer 1

It depends on the configuration of the domain controller. You may try:

net ads user info [e-mail] -S DC_SERVER_NAME -U USERNAME

[e-mail] - , DC_SERVER_NAME - , USERNAME - .
