Hello,
I had this issue today. One of my co-workers accounts was looked due to inactivity. The passwd -u command didn't work. So I did what I posted below. I don't think this the proper way to do this. What is the right to reactivate an account in Linux? After I changed the inactivity to never he was able to login.
bitlord@server
< sudo chage -l user
