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




    
Hi, thanks for your help. Your suggestion makes sense, however I think there should be some way for users to be able to change an expired password from login dialogue. 
Actually I had a problem doing this previously with NT4 style Samba domain and never looked into a resolution. 
Now that I've found Samba does AD style domain, I'm excited to use it in several customer locations. 
Since I can't find any info in the Samba documentation about a known problem or FAQ about expired password during Windows OS login, I figured it's /supposed/ to work.

Subject: 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 belowsamba-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

On win8.1 & srv2012r2 it is "The password for this account has expired"

What error message, *specifically*, comes up when the user with the expired password attempts to change it?

    To test, I use a desktop OS (win8.1) with rsat installed to create

    a new user with ADUC and set the "user must change password at

    next logon" OR for an existing user, with ADUC under "Account"

    tab. check "user must change password at next logon."



    Then, when the test user actually logs in to a Windows OS (I've

    tested win8.1 and srv2012r2), they get a message like "your

    password has expired and must be changed." When "ok" is clicked,

    they get a prompt to enter old password, and new password x2.

    Entering all of those correctly, including complexity

    requirements, does not work and that is my problem. They get an

    immediate repeat of the "the password for this account has

    expired" and the process starts all over.



    However, if for a non-expired user, they log in successfully and

    choose cntl-alt-del they can successfully change their password.
