Kerberos:kadmin 无法正常工作

Question

我在让我的 kadmin 工作时遇到一些麻烦。 kadmin.local 中一切正常，但每当我使用 kadmin 时，它似乎正在使用 kadm5.acl 文件，但事实并非如此。

我在这个文件中有: $ cat/var/kerberos/krb5kdc/kadm5.acl

kadmin 可以正确连接到 kdc 服务器，并且 dns 查找和反向 dns 也可以工作。

我的krb5.conf是这样的: $ cat/var/kerberos/krb5kdc/kdc.conf

[kdcdefaults]
    kdc_ports = 750,88

[realms]
    HADOOP.COM = {
        admin_keytab = FILE: /var/kerberos/krb5kdc/kadm5.keytab
        kadmind_port = 749
        kdc_ports = 750,88
        max_life = 10h 0m 0s
        max_renewable_life = 7d 0h 0m 0s
        database_name = /var/kerberos/krb5kdc/principal
        acl_file = /var/kerberos/krb5kdc/kadm5.acl
        #key_stash_file = /var/kerberos/krb5kdc/.k5.HADOOP.COM
}

和 $ cat/etc/krb5.conf

[logging]
    default = FILE:/var/log/krb5libs.log
    kdc = FILE:/var/log/krb5kdc.log
    admin_server = FILE:/var/log/kadmind.log

[libdefaults]  
    default_realm = HADOOP.COM
    dns_lookup_realm = false 
    dns_lookup_kdc = false
    ticket_lifetime = 24h
    forwardable = yes

[realms]
    HADOOP.COM = {
    kdc = evl2400469.eu.verio.net:88  
    admin_server = evl2400469.eu.verio.net:749
    default_domain = hadoop.com 
}

[domain_realm]
    .hadoop.com = HADOOP.COM
    hadoop.com = HADOOP.COM

因此，当我尝试执行添加主体或获取主体列表等操作时，我得到: kadmin: 列表王子 get_principals:检索列表时操作需要“列表”权限。 kadmin: getprivs 当前权限:获取添加修改删除

我真的不知道我的配置问题出在哪里。

我什至尝试在使用 kadmin 控制台之前获取票证: $ klist

Ticket cache: FILE:/tmp/krb5cc_0 Default principal:
 kadmin/<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="aacbcec7c3c4eae2ebeee5e5fa84e9e5e7" rel="noreferrer noopener nofollow">[email protected]</a>

 Kerberos 4 ticket cache: /tmp/tkt0 klist: You have no tickets cached

非常感谢您的帮助:)

尝试编辑 /var/kerberos/krb5kdc/kadm5.acl

需要重新启动 kadmind 守护进程才能使 ACL 文件中的更改生效:

service kadmind restart
