Can not Log in Linux with Windows user

I have recently upgraded my system from Samba 2.7 to Samba 3.0.2a

I am on a 2K Domain running in mixed mode named FLORIDA and I was able to add my Linux system (MDKFTP) successfully to the domain.  It is recognized in Network Neighborhood, and when I double click on it asks me to authenticate.  When I try to put in my Windows username (FLORIDA\dthomas or FLORIDA+dthomas) and password it does not authenticate.  When I checked auth.log it displayed the following:

pam_winbind[21813] request failed: Access Denied, PAM error was 4, NT_Status_Access_Denied
pam_winbind[21813] internal module error: (retval = 4, user = FLORIDA\dthomas)

I am trying to share this directory with Windows:  /var/ftp/ftp/

The following functions work on MDKFTP:

wbinfo -t  : It says that the secret is good
wbinfo -g: It shows all the groups in AD
wbinfo -u: It shows all the users in AD
getent passwd: It shows all the users
getent group: It shows all the groups

On my box there is a directory of examples.

find / -name smb.conf

Try using and editing one of them.
I would start with the one that says simple.

For testing I always make myself root equivalent in the smb.conf file and do a real simple share eg

   comment = Share to give files to Third Party
   path = /home/exceed/interface
   read only = no
   writeable = yes
   public = yes
   guest ok = yes

In the past when I have had probelms it was normally because the files created at unix level or directory created at unix level had permissions that the guest user couldn't use.

So for testing make sure the directory is chmod 777 /testing and the files init are xwrxwrxwr - for simplicity.

Once all ok then add the required security

I hope this helps a bit

It sounds like a pam/winbind issue to me. I recently setup samba 3 on debian and was having very similar issues. I can't remember exactly what I did to resolve the issue, but it did involve modifying the pam settings.

Looking at the settings that I have;
pam.d/login has:
auth       sufficient   pam_winbind.so
account    required     pam_winbind.so
session    required     pam_mkhomedir.so skel=/etc/skel umask=0077

pam/samba has account sufficient not account required.
I also have an entry session sufficient pam_winbind.so in my common-session settings (sorry, debian does it a little differently) and I couldn;t see an equivalent in your settings.

Hope this makes sense, and helps!
