![]() ![]() Can you think of any reason why some would be sharing okay but others requiring a username and password? I also discovered that if I add a new shared folder to the list in the Sharing settings on the mac, it does not appear in the browse for new share under Zeroconf Browser or Windows Network (SMB), but the others all do. This means the initial shares were working fine without guest access. Hi, I only added the guest access after discovering the two shares that weren't working. In Kodi you will need to use "Add network location." via the GUI, enter all details for the SMB source, and things should work again. ![]() if you can still access shares via guest access, then your server(s) still have SMBv1 actief. Guest accounts will no longer be used as that was one of the big problems resulting in 'WannaCry'.Īlso network browsing will no longer work for SMB. This also means your SMB server requires a user with full credentials, aka including a password. And sure enough, my GPO software installations deployed successfully.(, 23:53)Klojum Wrote: SMBv1 is (finally) no longer deemed secure by Microsoft, so SMBv2 is now active via various updates, quite likely also on your Apple contraptions. (Make sure the domain user you will use to manage permissions on the files in the share is either the owner of the files or a member of the group that does at the UNIX level.)Īfter all of that, testing from a Windows box using psexec.exe -i -s -d cmd.exe then issuing net use \\server\share /user:%COMPUTERNAME%$ no longer results in the dreaded error message but instead the very welcome The command completed successfully. I ended up saving off the existing smb.conf, removing the machine from the domain, purging all Samba config files/packages, reinstalling the packages (on Debian, I needed samba, samba-vfs-modules and libnss-winbind,) configuring afresh as a domain member according to this Samba wiki page (I used Idmap ad FWIW), then setting ownership of the share target directories on the Samba box as described in the above Windows ACL article before I could set NTFS and share permissions in Computer Management. ![]() In my case, since my Samba configuration was originally set up in the 3.x days, it needed an overhaul. This access is given via either a UCINetID if the authorized guest is a UCI student/employee or to other guests via aThird-Party UCINetID (TPID).A TPID is a unique user name/password that UCI provides to the guest for access to view the ZOT Bills online. World-readable should suffice, but I ended up setting Samba to use Windows ACLs for shares as described (very well!) on the Samba wiki.īut if your Samba machine isn't completely/correctly integrated into the domain, that's much easier said than done. Students may grant guest access to trusted family or friends so that they can view the students ZOT Bills online. Then of course the share itself needs to grant permissions to computer accounts. To fix that, you need to add a linux account for the computer account ("COMPUTER$") and you need some kind of identity mapping (idmap) set up to ensure that computer account Kerberos principal ("DOMAIN\COMPUTER$") is matched to the UID of this new COMPUTER$ linux account. The key point is to remove/comment out any map to guest line in your smb.conf (or set it to the default of never.) This disables unauthenticated user access which will make newer Windows happy.īut it creates the problem where machine accounts can't access the share in the event you're hosting software installation files there for deployment via GPO. How can I configure Samba so that Windows 10 will prompt the user for credentials, rather than attempting to use an insecure guest logon?Īfter many hours of searching and cursing, I have the answer, at least for a domain/Active Directory environment. Noting that the error message refers to SMB2, I tried adding the line server min protocol = SMB3 to /etc/samba/smb.conf in the section, but this didn’t change anything. I don’t need to support any legacy clients I just want to access the share from one Windows 10 machine with a username and password. My Samba credentials work as expected.īut I don’t want to enable anything insecure! I’ve tried to disable all the default shares that are guest-accessible, and I’m happy to give up the ability to be able to browse \\servername (although it would be nice to have). I can browse \\servername without entering any credentials, and if I try to access \\servername\sharename, I’m asked for a username and password. If I use the Enable insecure guest logons group policy option, as suggested in the documentation, everything works fine. This is documented by Microsoft at Guest access in SMB2 disabled by default in Windows 10, Windows Server 2016 version 1709, and Windows Server 2019. ![]() These policies help protect your PC from unsafe or malicious devices on the network. You can't access this shared folder because your organization's security policies block unauthenticated guest access. But whenever I try to open the paths \\servername or \\servername\sharename in Windows, I get this error message: I’ve just set up a new Ubuntu 18.10 server with a single SMB share which I’d like to access from Windows. ![]()
