/var/log/cron.log 返回 CRON[PID]: 域加入账户的权限被拒绝

我正在尝试运行一个 cron 作业，但不是以 root 身份运行。

在用户上下文中（[电子邮件保护]），以下是 crontab 和 cron.log 的输出：

crontab -l 的输出

    # Edit this file to introduce tasks to be run by cron.
    #
    # Each task to run has to be defined through a single line
    # indicating with different fields when the task will be run
    # and what command to run for the task
    #
    # To define the time you can provide concrete values for
    # minute (m), hour (h), day of month (dom), month (mon),
    # and day of week (dow) or use '*' in these fields (for 'any').#
    # Notice that tasks will be started based on the cron's system
    # daemon's notion of time and timezones.
    #
    # Output of the crontab jobs (including errors) is sent through
    # email to the user the crontab file belongs to (unless redirected).
    #
    # For example, you can run a backup of all your user accounts
    # at 5 a.m every week with:
    # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
    #
    # For more information see the manual pages of crontab(5) and cron(8)
    #
    # m h  dom mon dow   command

这显然是一个权限问题，但我不确定需要在哪里分配权限。

答案1

因此该问题与 GPO 有关，因为该盒子已加入 AD 域。

按照https://bugs.launchpad.net/ubuntu/+source/sssd/+bug/1572908，以下修复了它：

编辑/etc/sssd/sssd.conf
添加ad_gpo_access_control = permissive到[domain/corp.contoso.com]部分。

完整示例/etc/sssd/sssd.conf

    [sssd]
    domains = corp.contoso.com
    config_file_version = 2
    services = nss, pam

    [domain/corp.contoso.com]
    ad_domain = corp.contoso.com
    krb5_realm = CORP.CONTOSO.com
    realmd_tags = manages-system joined-with-adcli
    cache_credentials = True
    id_provider = ad
    krb5_store_password_if_offline = True
    default_shell = /bin/bash
    ldap_id_mapping = True
    use_fully_qualified_names = True
    fallback_homedir = /home/%d/%u
    access_provider = ad
    ad_gpo_access_control = permissive
