我正在尝试在 centOS 6.6 上配置 OPENLDAP，我已经通过 yum 安装程序安装了它，并下载了 openldap-server openldap-client openldap 的 2.4.39-8 版本。

我遵循了 http://www.thegeekstuff.com/2015/01/openldap-linux/ http://dopensource.com/openldapforlinuxauth/上的教程

我继续并通过输入 slappasswd 添加了密码，它给了我一个 olcRootPW: {SSHA} 我在 /etc/openldap/slapd.d/cn=config/olcDatabase={2}bdb 下添加的密码.ldif

我还将 olcsuffix:dc=my-domain,dc=com 更改为 olcsuffix:dc=mycompanyname,dc=com

olcRootDN:cn=Manager,dc=my-domain,dc=com 到 olcRootDN:cn=Manager,dc=mycompanyname,dc=com

我运行 ldaptest -u 来测试连接，但它给了我以下错误： 5577050f ldif_read_file: checksum error on "/etc/openldap/slapd.d/cn=config.ldif" 5577050f str2entry: entry -1 has no dn slaptest : 错误的配置文件！

我用谷歌搜索了上述错误，但没有运气。

Below are my cn=config.ldif and my olcDatabase={2}bdb.ldif

如果您发现自己遵循要求您手动修改以下文件的说明：

# AUTO-GENERATED FILE - DO NOT EDIT!! Use ldapmodify.

考虑到您可能正在寻找一条不太理想的路径。

CentOS 6 上的默认 openldap 安装包括以下 ACL，定义在slapd.d/cn=config/olcDatabase={0}config.ldif：

olcAccess: {0}to *  by dn.base="gidNumber=0+uidNumber=0,cn=peercred,cn=external,
  cn=auth" manage  by * none
olcAddContentAcl: TRUE

这允许您cn=config使用外部身份验证在没有 UID 0（“root”）密码的情况下进行访问。看起来像：

ldapsearch -Y EXTERNAL -H ldapi:/// -b "cn=config"

有了这个访问权限，您几乎可以做所有需要做的事情，包括修改目录树的后缀和根 dn。将以下内容放入access.ldif：

dn: olcDatabase={2}bdb,cn=config
changetype: modify
replace: olcSuffix
olcSuffix: dc=mycompanyname,dc=com
-
replace: olcRootDN
olcRootDN: cn=manager,dc=mycompanyname,dc=com
-
replace: olcRootPW
olcRootPW: {SSHA}ZvsONlpgNnLlAqKDRQBFup/W+0/LXm5q

然后使用它来修改配置：

# ldapmodify -Y EXTERNAL -H ldapi:/// -f access.ldif

现在您已经修改了目录后缀和密码，您可以将以下内容放入toplevel.ldif：

dn: dc=mycompanyname,dc=com
objectclass: dcObject
objectclass: organization
dc: mycompanyname
o: my company name

然后添加它：

# ldapadd -D cn=manager,dc=mycompanyname,dc=com -w admin -f toplevel.ldif
adding new entry "dc=mycompanyname,dc=com"

现在您可以搜索它：

# ldapsearch -x -b dc=mycompanyname,dc=com
# extended LDIF
#
# LDAPv3
# base <dc=mycompanyname,dc=com> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# mycompanyname.com
dn: dc=mycompanyname,dc=com
objectClass: dcObject
objectClass: organization
dc: mycompanyname
o: my company name
