Re: [Samba] Changing expired Samba AD password during Windows login




Hi Ken

I was experiencing a similar problem with the passwords few days back when
the staff resumed to work after a months vacation. The clients are Windows
7 PC's which were failing to login with an error"The password for this
account has expired" even after a password reset from RSAT.

Solutions which worked for me:
When you are resetting use password uncheck the option to change password
on next login which means user can login with the new password and later
they can change it from the ctrl+alt+del menu.

To reset the user password without checking to change password on next
login you can use the below command line:
samba-tool user setpassword --filter=samaccountname=username
--newpassword=password
or you can also use command below to reset the user password if you
remember the old password
kpasswd username

Also you can change password settings on Samba 4 using the command below
samba-tool domain passwordsettings set --history-length=0
samba-tool domain passwordsettings set --min-pwd-age=0
samba-tool domain passwordsettings set --max-pwd-age=90

Thanks n Regards
