SID security
After sending the email I realized that I did not mention that while rebuilding the OS, I kept the "old" /srv/samba files. Which in turn kept the old permission settings. I think (could be wrong) that keeping the old SID are now different from the new SID's created while rebuilding to v4.12.6. To answer your DC question: root at dc1:~# wbinfo -s

SID security
As the result of my own actions I have had to rebuild my DC's and member server Samba version. It's my fault for upgrading to v4.13.0 too soon. On W10, logged in as administrator, connected to the member server via FileExplorer, the file permissions (via Properties tab) >> Security (tab >> Advanced >> shows the following permissions for the \\mbr04\data folder: Creator

winbind sometimes does not resolve sid to a name
Sometimes a group sid does not get resolved to its name. Is this a settings problem? Looks like winbind deamon went dormant for a while and then woke up? I am using interface wbcLookupSid provided by the library libwbclient.so for resolving sids to names. These are the winbind related parameters in /etc/samba/smb.conf [global] # separate domain and username with '\', like

SID security
Thanks to data backups I can "whip out" the /srv directory and rebuild from scratch to "get permissions correct." Doing this because, yes, I did provision a new domain. (Probably faster to wipe, reconfigure dir and restore than correct the SID mistake.) Oh well, learning the hard way or as we like to call it around here, "OJT" (on the job training.) On Mon, Oct 5,

Security Principals, and SID's mapping bug
Hai, Does anyone know more if this is adressed or point me to the bug report? There should be one, but i cant find it. Im finding the following again, tested with samba 4.4.5, now samba 4.5.3. These reports go back to the year 2013. I searched in my mail samba folder for S-1-5-18 The problem. I create a "computer" Scheduled task. Now this task MUST run as : SYSTEM (S-1-5-18)

UID/GID -> SID -> NAME mapping across multiple DCs
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

Are you sure that was the only change? :-/ Tried it out, but wbinfo --lookup-sids=S-1-5-18 wbcLookupSids failed: WBC_ERR_INVALID_SID Could not lookup SIDs S-1-5-18 Does this possible has anything todo with AD/RID setups? Im on a AD setup. Selecting the users SYSTEM though search still resolve back to NTDOM\System :-) Well.. lunch first. Greetz, > > -----Oorspronkelijk bericht----- &...

Got "I have no name!" error after deleting a samba user whose username is identical to the AD user
Hi, I am running Samba 4.3.11-Ubuntu on a cluster of Ubuntu 16.04 and Samba is configured as an AD Server.

We used `smbpasswd -a zhangyy` to created a new smb user. 2. We used `smbpasswd -x zhangyy`
