24.11.1 LDAP 目录中的 CA 证书

以下示例将某个证书授权机构的证书添加到 LDAP 目录中。这些证书的目录结构已经存在。证书及其所属的 LDAP 条目将被输入到名为 add-root-CA-cert.ldif 的 .ldif 文件中。除了证书信息必须以 Base64 编码文本形式输入外，所有文本都将以 ASCII 文本形式输入到文件中：

dn: cn=SMIME Admin,ou=people,o=demo.siroe.com,o=demo
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: certificationAuthority
cn: RootCACerts

使用 ldapmodify 命令将 CA 的证书添加到 LDAP 目录中：

# ldapmodify -a -h demo.siroe.com -D "cn=Directory Manager" -w mypasswd -v
 -f add-root-CA-cert.ldif

smime.conf 中 trustedurl 参数的值指定了 CA 证书在 LDAP 目录中的位置。例 1，按以下方式设置 trustedurl：

trustedurl==ldap://demo.siroe.com:389/cn=SMIME Admin, ou=people, 
o=demo.siroe.com,o=demo?cacertificate;binary?sub?
(objectclass=certificationAuthority)
