LDAP TSL ldap_modify：错误 80

  • 772

我从这个论坛和许多其他论坛中读到了一些建议，并尝试自己解决问题，但没有结果。我需要将证书添加到 ldap 并始终返回错误 80。

我是使用 ldap 向文件夹添加权限：

ls -la /etc/apache2/ssl/
razem 16
drwxrwxr-- 2 root root 4096 cze 29 12:52 .
drwxr-xr-x 9 root root 4096 lip  2 10:33 ..
-rwxrwxr-- 1 root root 1545 gru 22  2017 od.censored.pl.crt
-rwxrwxr-- 1 root root 1704 gru 22  2017 od.censored.pl.key

我正在检查临时目录的权限：

ls -la /var/lib/lda*
razem 708
drwxr-xr-x  2 openldap openldap     4096 lip  2 10:39 .

certs.ldif 看起来：

cat -n certs.ldif 
     1  dn: cn=config
     2  changetype: modify
     3  replace: olcTLSCertificateFile
     4  olcTLSCertificateFile: /etc/apache2/ssl/od.censored.pl.crt
     5  
     6  dn: cn=config
     7  changetype: modify
     8  replace: olcTLSCertificateKeyFile
     9  olcTLSCertificateKeyFile: /etc/apache2/ssl/od.censored.pl.key

但我一遍又一遍地看到错误：

ldapmodify -Y EXTERNAL -H ldapi:/// -vvv -f certs.ldif
ldap_initialize( ldapi:///??base )
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
replace olcTLSCertificateFile:
    /etc/apache2/ssl/od.censored.pl.crt
modifying entry "cn=config"
ldap_modify: Other (e.g., implementation specific) error (80)

请为任何建议如何解决它。

这个问题对我来说是个大问题，因为我无法完成必要服务器的配置，请寻求帮助。

    如果openldap是运行 OpenLDAP 的 slapd 的系统用户，则问题中列出的此所有权/权限不允许 slap 读取服务器证书和私钥：

    ls -la /etc/apache2/ssl/
razem 16
drwxrwxr-- 2 root root 4096 cze 29 12:52 .
drwxr-xr-x 9 root root 4096 lip  2 10:33 ..
-rwxrwxr-- 1 root root 1545 gru 22  2017 od.censored.pl.crt
-rwxrwxr-- 1 root root 1704 gru 22  2017 od.censored.pl.key

    与例如 Apache slapd相反，即使在使用静态配置文件时，也会在调用后初始化SSLContext 。setuid()并且对于动态配置 (cn=config)，无论如何它都必须在处理 LDAP 修改期间读取文件。

    因此尝试这个来修复组所有权：

    chgrp -R openldap /etc/apache2/ssl

    并删除不需要的 exec 权限：

    chmod 0640 /etc/apache2/ssl/od.censored.pl.crt /etc/apache2/ssl/od.censored.pl.key
    • 1

  2. Ubuntu 16.04 - apparmor 不喜欢将证书放在其他地方用于 slapd

    从我们的日志

    audit: type=1400 audit(1576557786.149:51): apparmor="DENIED" operation="open" profile="/usr/sbin/slapd" name="/usr/local/etc/ssl_certs/our.pri_key" pid=15900 comm="slapd" requested_mask="r" denied_mask="r" fsuid=114 ouid=0

    通过禁用 slapd 的 apparmor 并重新启动来修复

    root@alc-jw-test5:~# ls -l /etc/apparmor.d/disable/usr.sbin.slapd
lrwxrwxrwx 1 root root 30 Dec 17 15:43 /etc/apparmor.d/disable/usr.sbin.slapd -> /etc/apparmor.d/usr.sbin.slapd

  3. 我解决了这个问题，只是按照正确的顺序使用第一个密钥，然后是证书。它对我有用。

    dn: cn=config
changetype: modify
replace: olcTLSCertificateKeyFile
olcTLSCertificateKeyFile: /etc/openldap/certs/myldap.kart.com.key 

dn: cn=config
changetype: modify
replace: olcTLSCertificateFile
olcTLSCertificateFile: /etc/openldap/certs/myldap.kart.com.cert

  4. 我遇到了这个问题，我尝试了很多解决方案，最终得出的结论是这是一个 apparmor 问题。我通过安装重新配置 slapd 配置文件解决了这个问题。

    所以首先我必须安装 app-armor 配置文件

    apt install apparmor-profiles

    其次，我不得不重新配置配置文件。因此，您将需要打开两个 ssh 会话，或者在一个屏幕会话中执行此操作，其中一个运行您的 ldap 命令，一个运行 aa-genprof。

    所以在一个会话中运行

    aa-genprof slapd

    您将看到类似这样的内容 > Profiling: /usr/sbin/slapd


    请在另一个窗口中启动要分析的应用程序并立即使用它的功能。
    完成后，选择下面的“扫描”选项
    以扫描系统日志以查找 AppArmor 事件。
    对于每个 AppArmor 事件，您将有
    机会选择是
    允许还是拒绝访问。
    [（S）可以记录 AppArmor 事件的系统日志] /（F）结束

    现在.. 在您的其他会话中运行您的 ldif 脚本或 ldapmodify 中的命令。

    在您的 genprof 会话中，您将扫描系统日志以查找 AppArmor 事件，您将获得允许该操作的选项....所以简单地说，当您完成并保存新配置文件时，允许它.. 哇哦！
