DB_NOTFOUND：未找到匹配的键/数据对（-30988）

DB_NOTFOUND：未找到匹配的键/数据对（-30988）

有人能解释一下我为什么会收到这个错误吗？我在尝试绑定 ldap 服务器中的任何用户时收到此错误（在服务器上）。此外，当我运行程序时，我收到“访问权限不足”输出。而我在尝试绑定管理员时没有收到此输出。我在 slapd.conf 中提供了访问控制，如下所示：

 access to *
        by self write
        by * read
        by anonymous auth

代码：

require 'net/ldap'
con = Net::LDAP.new
con.host = 'localhost'
con.port = 389
con.auth 'cn=user,dc=example,dc=com', '123'

if con.bind
  # authentication succeeded
  puts 'success'
  puts con.get_operation_result
else
  # authentication failed
  puts 'fail'
  puts con.get_operation_result
 # p con.get_operation_result
end

错误：

答案1

我没有看到“访问权限不足”错误，但我能看到这个错误：

 5a3e8945 bdb_dn2entry("cn=kerberoskdc,cn=config,dc=example,dc=com")
    5a3e8945 => bdb_dn2id("cn=config,dc=example,dc=com")
    5a3e8945 <= bdb_dn2id: get failed: DB_NOTFOUND: No matching key/data pair found (-30988)

可能与此条目相关：

cn=config,dc=example,dc=com
cn=kerberoskdc,cn=config,dc=example,dc=com

它存在于您的 LDAP 数据库中吗？
