![]() This is because the user nobody is the username windows clients use. Then go to the folder on the samba server that you want to share, and make sure that the user nobody can read and write to the share. You can do this by running the command below in the terminal. The first thing you should do is start over from scratch to make troubleshooting easier. ![]() I am using Linux mate at the server, all the latest updates. With that, I am able to see the shares and the server from the network, but it says that Windows cannot access them. The best I've managed to do so far is this configuration. The goal of the server is to host files for Windows machines. I'm making a server to host files for my home.

This Support Knowledgebase provides a valuable tool for SUSE customers and parties interested in our products and solutions to acquire information, ideas and learn from one another. rwxr-r- 1 user1 domain users 0 feb 18 13:51 foo.txt Putting file foo.txt as \\foo.txt (0,0 kb/s) (average 0,0 kb/s) # smbclient //localhost/share1 -U EXAMPLE\\user1 -c 'put foo.txt' Keep in mind that the command won't work if the foo.txt file already exists in the share (/srv/share1): Idmap config EXAMPLE : range = 200000-2000200000Īny user should be able to replace "user1" below. See the following TID for options and examples: Įxample in the “” section of the /etc/samba/smb.conf: It is important to select the appropriate idmap backend and to set the ranges properly. Either way the AD user must be able to create/modify computer accounts):Īfter CVE-2020-25717 patches it is necessary to set the correct idmap settings so winbindd will get the NSS information for AD users from sssd through NSS. Since we have also configured samba to update the system keytab, we can join using the “net” utility (”-U” could also be used. If the computer was already joined to the domain using adcli, we need to join again using “net” to create the secrets.tdb file for samba. # If the AD server requires password changes this will not be an option.Īd_maximum_machine_account_password_age = 0 Add to the /etc/sssd/nf one of the following parameters:Īd_update_samba_machine_account_password = true Likewise we can tell SSSD to update the secrets.tdb file. The netbios name of the AD server will be needed for the workgroup parameter. To prevent this problem, we have to tell samba to update the system keytab as well when the machine password is changed. If/When the password is changed by one of the services, the other service will stop working since it now has an outdated password. This can be a problem because the SSSD daemon stores the machine account password in the system keytab and samba stores it in the secrets.tdb file. The fallback behavior where smbd contacted the domain controller directly was removed in samba 4.8.Īlso, after CVE-2020-25717 patches, it is necessary to properly set up the idmap settings because fallback behavior ignoring the domain was removed.īoth SSSD and Winbind change the machine account password at regular intervals by default. It is not possible to run smbd without winbind. In this setup sssd will provide the NSS information for the AD users and winnindd will perform the authentication of the SMB sessions. Idmap config EXAMPLE : range = 20000-29999 See the following TID for options and examples: Example in the “” section of the /etc/samba/smb.conf: # chgrp "EXAMPLE\\Domain Users" /srv/share1Ĭonfigure idmap settings: It is important to select the appropriate idmap backend for your needs and to set the ranges properly. Additionally, it requires careful setup because both services will attempt to renew the computer account password at regular intervals which can end in one daemon or another not able to login. In that situation, when a user establishes an SMB session, SSSD provides the NSS information and smbd delegates the user authentication to Winbind. If you choose to use SSSD, but also want to run a samba file server, then running winbindd is mandatory since samba 4.8.
