Samba accepts ANY password and bypass to Windows Server Machine


When I try to connect to my Windows Server from Slackware using Samba, I get the password dialog.
I don't enter a password and click connect. The option chosen doesn't matter because this issue is the same.
I get a second (exactly the same) dialog and enter any password or character.
It bypasses and allows me to login into my Windows Server. Yes, my server has a very long..... password and so does my slackware box. This is definitely a security issue. Anyone know how to fix this?

Samba can't bypass the security on your Windows Server. That has to be a configuration issue on the server (it'd be a pretty serious bug and security hole if samba could just bypass passwords of Windows Server).

I haven't poked around with Windows Server since Windows 2000 Server, but the first thing I would check would be that all guest access is disabled. Beyond that, someone else would need to pipe in for suggestions.

I only have one account on the server and that is the Administrator.

Yes but the guest account can still be enabled for remote services, regardless if its visible on the login screen... What version of windows server are you running? Have you verified the guest account is disabled? The last version of Windows server I have used is 2003.

That still doesn't matter. This can't be an issue with samba. If you're able to get around the security in Windows Server, it is because of a configuration issue with Windows Server or a very serious bug of Windows Server. Samba can only try and connect and the server will either say yes or no.

If you try and log into the LQ forum using Firefox and you put in the wrong password but you still end up signed on, is that a Firefox issue or a server issue? There is no question that it is a server issue.

It was a permission setting on the server. Everything works as it should after re-configuration. Thanks
