[Samba] Samba 3.5 & CIFS mounts - long standing issue...
Hi. I can see that this is a long long standing issue... Apparently things changed in Windows 2008 R2, and after upgrade of domain from R1 to R2 cifs mounts don't work anymore between Linux servers. Windows can see Samba shares and mount them, but CIFS on another Linux box cannot... Here is a thread with explanation in lenght: http://ubuntuforums.org/showthread.php?t=1178484 I get the exact same logs and errors... I've tested with smbclient and everything works but with CIFS - no way :( Has anybody succeded in solving this one? Mount with CIFS: # mount -t cifs //server/share /mnt -o username=jakov.sosic,password=*******,domain=mydomain -v mount.cifs kernel mount options: unc=//server\share,ver=1,username=jakov.sosic,domain=mydomain,ip=xxx.xxx.xxx.xxx,pass=******** mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) Login with smbclient: # smbclient -U jakov.sosic //server/share Enter Administrator's password: Domain=[MYDOMAIN] OS=[Unix] Server=[Samba 3.5.4-0.83.el5_7.2] smb: \> I've tried adding various mount parameters like sec=ntlmv2, credentials=/path/to/file, but every attempt fails. Any ideas?!?!! Samba is version 3.5.4 on CentOS 5.7 on both Linux machines. -- Jakov Sosic www.srce.unizg.hr

I've added the following to smb.conf on the server: "map untrusted to domain = yes" restarted samba, tried - it wouldn't work. Removed that line, restarted again, tried again, now it works... Also, domain should be noted in lowercase. Don't know what fixed it ... Also if you have hidden share (with $ at the end of the name), you shouldn't escape it in /etc/fstab or in automount maps.
