我正在尝试将条目上传到 LDAP，但我不断收到错误消息。我已经在 STS 中安装了 LDAP 服务器，并创建了我的新分区：
name : messenger
id : o=messenger
cache=100
Auto generate Context Entry = unchecked
启动服务器并连接后，我尝试上传以下 ldif 文件：
dn: ou=roles, o=messenger
objectClass: top
objectClass: organizationalunit
ou: roles
dn: ou=people, o=messenger
objectClass: top
objectClass: organizationalunit
ou: people
dn: cn=USER, ou=roles, o=messenger
objectClass: top
objectClass: groupOfNames
cn: USER

objectclass: top
objectclass: person
objectclass: organizationalPerson
objectclass: inetOrgPerson
cn: Jovana Pozek
sn: Pozek
uid: Koala

但它不断失败并出现错误：
LDAP: error code 32 - NO_SUCH_OBJECT: failed for MessageType :

...

请帮忙。
