similar to: winbind: how to fix uid/SID mapping following migration to a new DC

Hi there. Our IT moved all the user accounts to a new domain controller. It wasn't much of a migration, more so a complete setup on a new machine, new OS, new domain ; it just happens that the username and group names remained the same. I have been asked to look after the migration of the existing unix servers (linux and freebsd running samba 3.4). All the unix machine use winbind for

Hi, when migrating a big linux/samba fileserver with several hundred local users/uids and more than a million files to a winbind/Windows AD setup, it's not desirable to have new uids assigned for all the users from a uid range by winbindd, because the file ownerships are messed up then. Is it possible to keep the original local uids for already existing users with winbind even after

Dear all I need some advise with respect to SID/UID/GID mapping. The server runs Samba 3.5.8 as a member of an AD (w2k8) domain. Our UNIX UIDs are taken from the 1000-60000 range with about 10000 allocated accounts. 99% of user IDs exist in AD with the same name. For that reason we rely on the "nss" idmap backend which is non-allocating. The problem comes with the group mappings.

Hi, I have a Samba 3.0 beta server set up as an NT Domain PDC (lets call it box S), a Windows 2000 client (box W) and a Linux member server in the domain (box L). All are configured as per the most recent 3.0/HEAD howto. S and L have the same users with same UIDs and login names in /etc/passwd and /etc/shadow. When browsing the domain from W, I can access all the shares on S and L. On S I can

Interesting... How do I go about getting them/keeping them in sync?

This isn't necessarily an issue (I don't think) but more so a curiosity. How are UIDs mapped to SIDs and then SIDs mapped to names in Samba4 across multiple DCs? I set up my DCs using Louis' how tos ( https://github.com/thctlo/samba4/tree/master/howtos). All of my DCs smb.confs have the line "idmap_ldp:use rfc2307 = yes" My policies folder under \sysvol\domainname\ has

I have read with great interest the chapter on IDMAP in the Samba 3 HOWTO. I was hoping to get some clarification from someone in the know as to the feasibility of using winbind in may setup. Here is what I want to do: 1. I would like to use winbind for a single sign on (SSO) type solution for integrating my linux clients with AD. The goal here is to eliminate local accounts from my linux

Hi. I have a problem with mapping SIDs to uids in Samba 2.2.6pre2. I am using Mandrake linux 8.2 with acls, and samba acting as PDC on my local net. My problem is what when I viewing permissions on my test WinXP box, it shows to me SIDs, but not a user or group, and of cource everyone... For example, I created user "test" on my linux box and added him to smbpasswd. Then, when I logon

Hi, I am sure somebody asks this question about once a week. Since I have not found an answer I assume the worst -- it just does not work. So, here goes my problem. I am testing Samba 3.0.0. I have got UNIX and Windows domain users matching each other one-to-one. The server is running with "security = domain". Everything works fine and all Windows users connecting to Samba get

Hi, Could you please tell me, what's happend when the UID/SID mapping changes for a computer account ? In my previous mail, I explain that suddenly every computers of my domain was unable to connect to our samba logon server. Before this problem, a 'net rpc vampire' was done to resynchronize the samba ldap-sam with the NT4 PDC, and samba has been restarted, I suspect that after

I have: linux 2.6.18-1.2200.fc5 samba-3.0.23c-1.fc5 W2000 AD with SFU 3.5 uid and gid in SFU linux configured to use AD with ldap client for mapping users, groups and authentication winbind not configured Everyting works fine except ACL in the linux filesystem: I receive this error when I want to add an user access to a file: [2006/10/18 09:38:28, 0]

ok, I followed the directions on that wikipage, made a hot backup, copied the hot backup over to the new DC, renamed the hot backup (thus replacing the existing idmap.ldb) and ran "samba-tool ntacl sysvolreset" and it spat out the following after a minute or 2 of thinking... root at dc1 samba/private# samba-tool ntacl sysvolreset open: error=2 (No such file or directory) ERROR(runtime):

Hi, i'am testing to setup a plain Samba PDC Domain. Now i habe the strange Problem, that the User Entry in Windows Security Dialog show different User that the underlying Samba Filesystem (XFS). In W2k is a User ACL called TKH\games, but such user isn't allow to do anything in the Filesystem, so what's going on ? Here some more Infos: debian:/var/log/samba# smbd -V Version

Hello I am deploying a samba network with a AD DC and a member server for file sharing. Samba version 4.5 on Debian 8. In AD DC everything goes fine. In member server, smb.conf:         netbios name = ADFS1         realm = CGSIBAD.SC         workgroup = CGSIBAD         client signing = yes         client use spnego = yes         kerberos method = secrets and keytab         server role = member

Apologies, despite that error, the permissions now look good on the sysvol folder. Is there anything I need to do moving forward to keep my DCs idmap.ldbs in sync? or is this a one time thing?

Hi there, I'm the process of centralizing user authentication for a medium-sized network with a few Linux servers, some of them runnng samba. The idea is migrating all user definitions from both /etc/{passwd,shadow,groups} and samba tdb to a central LDAP directory. Most servers had the same set of users, but as each one was administered in isolation (no NIS not all samba servers were part of

Hi I have a new Samba 3.6.10 server running on Solaris 10. The server is a member of the local Active Directory (which I'll call "DOMAIN" in this email). Unix username resolution is via NIS. All domain users have NIS usernames as well.Winbind is running to allow SMBD to perform sid>uid mapping and I have setup idmap_nss. I am not using winbind in /etc/nsswitch.conf as NIS

I've got a very simple need -- want to make a samba4 server a member of an active directory domain and use it as a file-server only. All shares on the file server are explicitly designed with a 'uniform access model' -- eg the user's in privileged groups can do anything to all files in the share (and despite their best attempts) they can't accidentally edit permissions on
