可以使用以下过程将 RHEL 8.x 桌面与 Active Directory (AD) 域相集成,以便进行智能卡重定向。

该过程中的一些示例使用占位符值以表示网络配置中的实体,例如,AD 域的 DNS 名称。请将占位符值替换为您的配置特定的信息,如下表中所述。

占位符值 描述
dns_IP_ADDRESS DNS 名称服务器的 IP 地址
rhel8sc.rzview2.com RHEL 8.0 系统的完全限定主机名
rhel8sc RHEL 8.0 系统的非限定主机名
rzview2.com AD 域的 DNS 名称
RZVIEW2.COM AD 域的 DNS 名称,全部为大写字母
RZVIEW2 包含 Samba 服务器的工作组或 NT 域的 DNS 名称,全部为大写字母
rzviewdns.rzview2.com AD 服务器的主机名

过程

  1. 在 RHEL 8.x 系统上,执行以下操作。
    1. 根据组织要求配置网络和 DNS 设置。
    2. 禁用 IPv6
    3. 禁用自动 DNS
  2. 配置 /etc/hosts 配置文件,使其类似于以下示例。
    127.0.0.1        rhel8sc.rzview2.com rhel8sc localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1              localhost localhost.localdomain localhost6 localhost6.localdomain6
     
    dns_IP_ADDRESS   rzviewdns.rzview2.com
  3. 配置 /etc/resolv.conf 配置文件,使其类似于以下示例。
    # Generated by NetworkManager
    search rzview2.com
    nameserver dns_IP_ADDRESS
  4. 安装 AD 集成所需的软件包。
    # yum install -y samba-common-tools oddjob-mkhomedir
  5. 启用 oddjobd 服务。
    # systemctl enable oddjobd.service
    # systemctl start oddjobd.service
    
  6. 指定系统身份和身份验证源。
    # authselect select sssd with-smartcard with-mkhomedir
    
    
  7. 启动 oddjobd 服务。
    # systemctl enable oddjobd.service
    # systemctl start oddjobd.service
    
  8. 要支持智能卡身份验证,请创建 /etc/sssd/sssd.conf 文件。
    # touch /etc/sssd/sssd.conf
    # chmod 600 touch /etc/sssd/sssd.conf
    # chown root:root /etc/sssd/sssd.conf
  9. 将所需内容添加到 /etc/sssd/sssd.conf 中,如以下示例中所示。在 [pam] 部分下,指定 pam_cert_auth = True
    [sssd]
    config_file_version = 2
    domains = rzview2.com
    services = nss, pam, pac
     
    [domain/RZVIEW2.COM]
    id_provider = ad
    auth_provider = ad
    chpass_provider = ad
    access_provider = ad
    cache_credentials = true
     
    [pam]
    pam_cert_auth = True
  10. 启用 sssd 服务。
    # systemctl enable sssd.service
    # systemctl start sssd.service
  11. 编辑 /etc/krb5.conf 配置文件,使其类似于以下示例。
    # To opt out of the system crypto-policies configuration of krb5, remove the
    # symlink at /etc/krb5.conf.d/crypto-policies which will not be recreated.
    includedir /etc/krb5.conf.d/
     
    [logging]
        default = FILE:/var/log/krb5libs.log
        kdc = FILE:/var/log/krb5kdc.log
        admin_server = FILE:/var/log/kadmind.log
     
    [libdefaults]
        dns_lookup_realm = false
        ticket_lifetime = 24h
        renew_lifetime = 7d
        forwardable = true
        rdns = false
        pkinit_anchors = /etc/pki/tls/certs/ca-bundle.crt
        spake_preauth_groups = edwards25519
        default_realm = RZVIEW2.COM
        default_ccache_name = KEYRING:persistent:%{uid}
     
    [realms]
     RZVIEW2.COM = {
         kdc = rzviewdns.rzview2.com
         admin_server = rzviewdns.rzview2.com
         default_domain = rzviewdns.rzview2.com
         pkinit_anchors = FILE:/etc/pki/nssdb/certificate.pem
         pkinit_cert_match = <KU>digitalSignature
         pkinit_kdc_hostname = rzviewdns.rzview2.com
     }
     
    [domain_realm]
     .rzview2.com = RZVIEW2.COM
     rzview2.com = RZVIEW2.COM
  12. 编辑 /etc/samba/smb.conf 配置文件,使其类似于以下示例。
    [global]
            workgroup = RZVIEW2
            security = ads
            passdb backend = tdbsam
            printing = cups
            printcap name = cups
            load printers = yes
            cups options = raw
            password server = rzviewdns.rzview2.com
            realm = RZVIEW2.COM
            idmap config * : range = 16777216-33554431
            template homedir =/home/RZVIEW2/%U
            template shell = /bin/bash
            kerberos method = secrets and keytab
     
    [homes]
            comment = Home Directories
            valid users = %S, %D%w%S
            browseable = No
            read only = No
            inherit acls = Yes
     
    [printers]
            comment = All Printers
            path = /var/tmp
            printable = Yes
            create mask = 0600
            browseable = No
     
    [print$]
            comment = Printer Drivers
            path = /var/lib/samba/drivers
            write list = @printadmin root
            force group = @printadmin
            create mask = 0664
            directory mask = 0775
  13. 加入 AD 域,如以下示例中所示。
    # net ads join -U AdminUser
    运行 join 命令将返回类似于以下示例的输出。
    Enter AdminUser's password:
    Using short domain name -- RZVIEW2
    Joined 'RHEL8SC' to dns domain 'rzview2.com'
  14. 确认 RHEL 8.x 桌面已成功加入 AD 域。
    # net ads testjoin
    
    Join is OK
