为什么 ldap_bind 无法针对 SimpleAD 进行身份验证?

Why is ldap_bind failing to authenticate against SimpleAD?

我有一个 AD ldap.patontheback.org,我正在尝试 ldap_bind 使用默认管理员帐户。我可以成功使用远程桌面来管理用户的同一帐户。

$ldapconn = ldap_connect("ldap://172.31.22.45");
ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, 7);
ldap_bind($ldapconn, "cn=Administrator,dc=ldap,dc=patontheback,dc=org", "<my password>");

可以连接,但不进行身份验证:

我已经三次检查密码是否正确。我从 windows 服务器获得的 LDAP 的 IP:

C:\Users\Administrator>nslookup ldap.patontheback.org
Server:  AWS-4A06F0BDB6.ldap.patontheback.org
Address:  172.31.22.45

Name:    ldap.patontheback.org
Addresses:  172.31.22.45
          172.31.2.194

我到底错过了什么?

所以我可以使用 UPN 作为标识让它工作:

ldap_bind($ldapconn, "Administrator@ldap.patontheback.org", "<password>");

它有效,但无法解释为什么另一种方法无效。

对于那些像我后来一样提出这个问题的人,正确的做法是

ldap_bind($ldapconn, "cn=Administrator,cn=Users,dc=ldap,dc=patontheback,dc=org", "<my password>");

cn=Users 是必须包含的路径。
