The weird thing is this i tried that too ... but i receive this error:
The following error occurred attempting to join the domain "MYDOMAIN": The specified account already exists.I had to delete to LDAP Workstation account every time that I tried a solution. To this time i see that problem that you mention on the internet but on Centos apparently there is not a workaround to this nss caching thing. The possible workarounds that I imagine is editing smbldap-useradd, on the workstation option including to do not exit if the workstation account exists (I do not know to much Perl). Or the easy one, once is created the workstation account on ldap directory, disable the add machine script and restart samba service. and then back again the Windows 2008 joinning process. Once the Windows 2008 is in the domain, enable the add machine script option and restart again. The ugly thing is that there are several Windows 7 workstations on the network.
How i can solve that nss error ? Thanks for your help German t...@tms3.com wrote:
SNIPHi there, this is my config, I have a CentOS 5.3 x86_64 full updated with Xen enabled with Samba 3.5.4 sernet RPMs. I have a virtual machine running Windows 2008 R2 Foundation running full virtualized on the same machine.When i tried to join the Windows 2008 to the domain i get this message: The following error ocurred attempting to join the domain "MYDOMAIN": A device attached to the system is not functioning.I have that error as well. To the best of my knowledge it is happening because smbldap tools are calling smbpasswd right after the ldap add of the machine, however, some nss dependent service is using a cached copy of ldap which does not contain the new machine entry. If you simply rejoin the domain after you receive the error, things should work fine.Cheers, TMS IIIThe Windows 2008 registry was modified to be able to join the domain as recommended on internet:|HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters DWORD DomainCompatibilityMode = 1 DWORD DNSNameResolutionRequired = 0 ||HKLM\System\CurrentControlSet\Services\Netlogon\Parameters DWORD RequireSignOrSeal = 0 DWORD RequireStrongKey = 0 | This is my config: smb.conf [global] unix charset = ISO8859-1 workgroup = MYDOMAIN netbios name = pdc passdb backend = ldapsam:ldap://127.0.0.1 username map = /etc/samba/smbusers log level = 10 log file = /var/log/samba/%m.log max log size = 50 name resolve order = hosts lmhost wins bcast wins support = yes time server = Yes show add printer wizard = No add user script = /usr/sbin/smbldap-useradd -a -m %u delete user script = /usr/sbin/smbldap-userdel -r %u add group script = /usr/sbin/smbldap-groupadd -p %g delete group script = /usr/sbin/smbldap-groupdel %g add user to group script = /usr/sbin/smbldap-groupmod -m %u %gdelete user from group script = /usr/sbin/smbldap-groupmod -x %u %gset primary group script = /usr/sbin/smbldap-usermod -g %g %u add machine script = /usr/sbin/smbldap-useradd -w -i %u passwd program = /usr/sbin/smbldap-passwd %upasswd chat = *New*password* %n\n *Retype*new*password* %n\n *all*authentication*tokens*updated*ldap password sync = Yes enable privileges = Yes logon script = %U.bat OR netlogon.bat logon path = \\%L\profiles\%U logon drive = H: domain logons = Yes preferred master = Yes domain master = Yes ldap admin dn = cn=Administrador,dc=mydomain,dc=local ldap group suffix = ou=Groups ldap idmap suffix = ou=Idmap ldap machine suffix = ou=Computers ldap passwd sync = Yes ldap suffix = dc=mydomain,dc=local ldap user suffix = ou=Users ldap ssl = off idmap backend = ldap:ldap://127.0.0.1 idmap uid = 10000-20000 idmap gid = 10000-20000 printer admin = Administrador map acl inherit = Yes printing = cups printcap name = CUPS [homes] comment = Home Directories valid users = %S read only = No browseable = No [netlogon] comment = Network Logon Service path = /var/lib/samba/netlogon guest ok = Yes locking = No [profiles] comment = Network Profiles Share path = /var/lib/samba/profiles read only = No profile acls = Yes create mode = 0600 directory mode = 0700 writable = yes browseable = No store dos attributes = Yes slapd.conf # # See slapd.conf(5) for details on configuration options. # This file should NOT be world readable. # include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/samba3.schema include /etc/openldap/schema/dyngroup.schema # Allow LDAPv2 client connections.
