Bom dia Eduardo, me desculpe. foi por inexperiência em Forum, mas tenho uma excelente notícia. Eu consegui resolver o problema. Para resolver o problema tem que atualizar o SAMBA do Endian que está na versão 3.2 que é incompatível com windows 2008 R2 para a versão 3.5.4. Segue abaixo o link para download e tambem as instrunções:
Encontrei esta solução agora e já testei e funcionou.
Problem:
Endian HTTP Proxy doesn’t work with Windows Server 2008 R2 Active Directory
Log errors on /var/log/samba/samba.log, like this:
winbindd[7024]: rpc_api_pipe: Remote machine domain.local pipe NETLOGON fnum 0x8003 returned critical error. Error was NT_STATUS_PIPE_DISCONNECTED
What cause it:
samba 3.2 is incompatible with ADS Windows 2008 R2
How to fix it:
Upgrade to samba 3.5.4.
1- Download Samba 3.5.4 packages from: http://www.megaupload.com/?d=BFYSNW6V
2-Copy the file EFW2.4_Samba_Fix.tgz to your firewall, the easiest way is with WinSCP
3-Unzip the file, either with WinSCP File->Custom Commands->Untar or using the command tar -xvf EFW2.4_Samba_Fix.tgz
4-Go to the directory called samba: cd samba
5-Run the installer: ./install.sh It should install all the packages involved correctly.
6-Reboot
Warning
It works as intented in my test machine, that’s all. I only tested it with Windows Server 2008 R2, I haven’t tested on any other AD server.
Use this patch at your own risk. I’m not responsible of any use or problem with these rpms (either good or bad).
If you want to see the sources, ask for them. There are a lot, though.
