Forums
ClearOS ClearFoundation and ClearCenter have moved to the new website ClearOS.com (https://clearos.com). We are making this change in order to improve search and exposure of ClearOS to the world. There are several improvements that are being made and some that are still on the table for development. The forums are now live on clearos.com and locked on this site until all the redirects are in place. If you have issues using the new site, feel free to ask on the #clearfoundation room in IRC chat on freenode.net or engage with a chat agent on the site if they are around. Our goal is to complete this step so that we can be properly ready for the types of communication that will be essential for the release of ClearOS 7!

Ah yes. You should also add the following line to the /etc/samba/smb.conf file:

passwd chat timeout = 10

By default, the password change request will only wait 2 seconds. That's not enough time for some systems (notably, our old file server). You may need to reload the Samba server after making this change:

service smb restart

Maybe if Peter explain us what the rmp does, we can contribute some help too.

Sure! The password request from a Windows desktop is handled by the /usr/sbin/userpasswd script. The first bug was just a typo... that was fixed. The second issue involves some magic that happens when Samba runs this script. If the passwords in LDAP are changed when Samba is running the script, you will get the warning message. By adding a workaround specifically for Samba, the password changes succeed.

In case you are wondering, the bug crept into 5.2 because of the changes required by the password policy system. Unfortunately, running a test using the /usr/sbin/userpasswd script directly doesn't catch the problem.

Confirmed!!!

I already changed a password using Ctrl + Alt + Del method!

Again Peter, thank you so much for the solution, and my humble congratulation to all the team to make ClearOS what it is right now.


PD.
Amazing that something as a few seconds can make.

I am very pleased to announce that mine is also working fine now thank you.

Not sure if this is worth mentioning, but since most people will have a password policy of "No Expire" or a long time, due to this problem having existed, it might. I changed the password policy while my desktop was logged on and on logging off, it came up with an error message about being unable to save my roaming profile. Starting again, I shutdown all computers and had no issues with the rest. In other words, it might be best to log off all computers before changing the "password policy" settings.

One possible issue I have come across in connection with this is that logging on or changing password on my Windows Vista Business Edition Desktop takes an absolute age, despite the fact that it is by far the fastest computer on our network (all the rest run XP Pro).

The first time I tried to change my password, it hung for 5 minutes saying it was changing the password. It is not unusual for it to take that long to log on as well. All of the xp machines log on in seconds as you would expect.

It's not a major issue to me as I really hate Vista and wanted an excuse to get rid of it.

The Windows Event for the logon and logoff is Winlogon 6005 "The winlogon notification subscriber <Profiles> is taking long time to handle the notification event (Logon)."

OK, ignore my last 2 messages please. I am feeling very dumb right now.

I set up my server with roaming profiles for 1 good reason. I couldn't trust the people in my office to make sensible use of the U: drive so that they would have access to their files from any computer. I should have taken my own advice. The reason my computer was taking so long to log on and off is that it was synchronizing my user profile, which had become rather large due to my use of the documents and downloads folders. A quick bit of housekeeping onto the U: drive and suddenly my computer logs on and off in a fraction of the time.

I can understand why Roaming Profiles are not entirely recommended, though in our office, unfortunately necessary.

According to the first error message, the password is the wrong length. Have you tried with a longer password?

Have you applied the "passwd chat timeout = 10" change and installed the new RPM?
