Hi! I have upgraded my servers yesterday to CentOS 5.6 via yum update. Everything went smoothly except that i have client workstations not part of the domain that are not able to access the samba server anymore. The samba server is part of the domain. We recently added Windows 2008 R2 DC. Everything was working smoothly until the CentOS update. I had a Win7 Workstation that i had success connecting when using the "net use" command: net use g: \\sambaserver\share /user:domain\username The mapping worked right away and didn't even asked for the password. Normally, before the CentOS upgrade, i'd put \\sambaserver in the UNC line of the Windows Explorer and i'd get a box asking for credentials. Entering "domain\username" as user and giving the password in the password line was working. Not anymore. I have another XP workstation on another subnet (router wide open) and the mapping with the command line as specified above doesn't even work. For this subnet, i have to use the IP address because the workstations on it use a DNS which isn't aware or active directory (and cannot change this). samba-3.0.33-3.29.el5_6.2 samba-common-3.0.33-3.29.el5_6.2 Here is my smb.conf: =================== [global] workgroup = DOMAINNAME realm = DOMAINNAME.COM server string = Servername File Server socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 security = ADS encrypt passwords = yes passdb backend = tdbsam password server = * preferred master = No local master = No domain master = No cups options = raw hosts allow = 10.0.2., 10.0.3., 127., 10.0.4.40 pam password change = Yes passwd program = /usr/bin/passwd %u passwd chat = *New*Password* %n\n *Re-enter*new*password*%n\n *Password*changed* username map = /etc/samba/smbusers unix password sync = Yes log level = 1 syslog = 0 log file = /var/log/samba/%m max log size = 50 smb ports = 139 name resolve order = bcast hosts time server = Yes printcap name = CUPS show add printer wizard = No add user script = /usr/sbin/useradd -m '%u' delete user script = /usr/sbin/userdel -r '%u' add group script = /usr/sbin/groupadd '%g' delete group script = /usr/sbin/groupdel '%g' add user to group script = /usr/sbin/usermod -G '%g' '%u' add machine script = /usr/sbin/useradd -s /bin/false -d /tmp '%u' shutdown script = /var/lib/samba/scripts/shutdown.sh abort shutdown script = /sbin/shutdown -c # separate domain and username with '\', like DOMAIN\username winbind separator =+ # use uids from 10000 to 20000 for domain users idmap uid = 10000-20000 # use gids from 10000 to 20000 for domain groups idmap gid = 10000-20000 # allow enumeration of winbind users and groups winbind enum users = yes [homes] comment = Home Directories read only = No browseable = No writable = yes [Videotheque] comment = Fichiers MPEG2 path = /home/Samba/Videotheque read only = No available = Yes public = Yes writable = yes admin users = domainname+user1,domainname+user2,domainname+user3 TIA, Guy Boisvert -------------- next part -------------- An HTML attachment was scrubbed...
