红帽全球峰会3.3. Installing and configuring a Samba server on an IdM client
You can install and configure Samba on an IdM client to securely share files with integrated authentication, leveraging IdM domain accounts for access. Ensure proper prerequisites and configuration to enable seamless resource sharing across your network.
Prerequisites
- Both the IdM servers and the client must run on RHEL 10 or later.
- The IdM domain is prepared as described in Preparing the IdM domain for installing Samba on domain members.
- If IdM has a trust configured with AD, enable the AES encryption type for Kerberos. For example, use a group policy object (GPO) to enable the AES encryption type. For details, see Enabling AES encryption in Active Directory using a GPO.
Procedure
Install the
ipa-client-sambapackage:[root@idm_client]# dnf install ipa-client-sambaUse the
ipa-client-sambautility to prepare the client and create an initial Samba configuration:[root@idm_client]# ipa-client-samba Searching for IPA server... IPA server: DNS discovery Chosen IPA master: idm_server.idm.example.com SMB principal to be created: cifs/idm_client.idm.example.com@IDM.EXAMPLE.COM NetBIOS name to be used: IDM_CLIENT Discovered domains to use: Domain name: idm.example.com NetBIOS name: IDM SID: S-1-5-21-525930803-952335037-206501584 ID range: 212000000 - 212199999 Domain name: ad.example.com NetBIOS name: AD SID: None ID range: 1918400000 - 1918599999 Continue to configure the system with these values? [no]: yes Samba domain member is configured. Please check configuration at /etc/samba/smb.conf and start smb and winbind servicesBy default,
ipa-client-sambaautomatically adds the[homes]section to the/etc/samba/smb.conffile that dynamically shares a user’s home directory when the user connects. If users do not have home directories on this server, or if you do not want to share them, remove the following lines from/etc/samba/smb.conf:[homes] read only = noShare directories and printers. For details, see:
Open the ports required for a Samba client in the local firewall:
[root@idm_client]# firewall-cmd --permanent --add-service=samba-client [root@idm_client]# firewall-cmd --reloadEnable and start the
smbandwinbindservices:[root@idm_client]# systemctl enable --now smb winbind
Verification
Run the following verification step on a different IdM domain member that has the samba-client package installed:
List the shares on the Samba server using Kerberos authentication:
$ smbclient -L idm_client.idm.example.com -U user_name --use-kerberos=required lp_load_ex: changing to config backend registry Sharename Type Comment --------- ---- ------- example Disk IPC$ IPC IPC Service (Samba 4.15.2) ...For more information, see the
ipa-client-samba(1)man page on your system.
