Alfresco支持LDAP验证

来源网络，实际是否有效本人没有验证过

这里说的活动目录指的是公司内的AD服务器。希望能通过AD账户来访问Alfresco网站并设置相应的权限。

根据alfresco的官方做法，需要配置一个验证链。

首先用alfrescoNtlm来提供Ntlm验证功能；其次用passthru子系统把用户提供的用户名和密码转交给AD服务器进行验证；最后加上一个ldap-ad在alfresco和AD其同步账户。

创建子系统配置文件

这里有三个子系统，分别是alfrescoNtlm，passthru和ldap-ad。

验证链

首先要在alfresco-global.properties里声明验证链
验证链的声明格式如下：

authentication.chain=id1:type1,id2:type2......idn:typen

所以需要加入以下验证链：

authentication.chain=alfrescoNtlm1:alfrescoNtlm,passthru1:passthru,ldap1:ldap-ad

验证链的第一个一定要声明alfrescoNtlm，后面两个一个用来验证的，一个是用来同步的，所以顺序没有关系。

配置文件

新建以下三个目录
tomcat/webapps/alfresco/WEB-INF/classes/alfresco/extension/subsystems/Authentication/afrescoNtlm/alfrescoNtlm1
tomcat/webapps/alfresco/WEB-INF/classes/alfresco/extension/subsystems/Authentication/passthru/passthru1
tomcat/webapps/alfresco/WEB-INF/classes/alfresco/extension/subsystems/Authentication/ldap-ad/ldap1

再把相应验证子系统中的properties文件拷贝到目录里，

tomcat/webapps/alfresco/WEB-INF/classes/alfresco/extension/subsystems/Authentication# ls -R
.:

注意事项

1. 所有的配置更改后都必须重启服务
2. ldap-ad中的验证功能必须关闭，否则和passthru冲突
3. AD的UPN是%s@domain.local
