在将服务安全性更改为私有ArcGIS Manager后，链接到免费的wms服务会引发错误 - 禁止使用。
QGIS如何正确配置Tomcat以允许安全访问服务？
ApacheDS配置：
用户：
Windows server 2012 R2
ArcGIS Server 10.5
ApacheDS 2.0.0-M23
Apache-tomcat 7.0.65
Web Adaptor Java Windows 105_154008
Windows firewall - off
基团：
cn: username1
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: person
objectClass: top
sn: username1
uid: username1
userPassword: userpassword
ArcGIS Server安全性 - 配置设置
1.用户和角色管理 - 来自现有企业系统（LDAP或Windows域）的用户和ArcGIS Server内置存储中的角色
2.Enterprise Store Type - LDAP
3.LDAP用户商店：
cn: Administrators
objectClass: groupOfUniqueNames
objectClass: top
uniqueMember: cn=username1,ou=users,ou=system
4.身份验证层 - 网络层
