• 【FBA】SharePoint 2013自定义Providers在基于表单的身份验证(Forms-Based-Authentication)中的应用


    //http://www.cnblogs.com/OceanEyes/p/custom-provider-in-sharepoint-2013-fba-authentication.html

    由于项目的需要,登录SharePoint Application的用户将从一个统一平台中获取,而不是从Domain中获取,所以需要对SharePoint Application的身份验证(Claims Authentication Types)进行更改,即采用更加灵活的混合模式登录:Windows Authentication和Forms Based Authentication。故本篇博客将着重笔墨去介绍SharePoint 2013自定义Providers在基于表单的身份验(Forms-Based-Authentication)中的应用。

    更改身份验证

    首先需要了解的一点事,怎样去更改指定的Web Application 的身份验证。进入SharePoint 2013 Central Administration-àApplication Management-àManage Web Applications-àAuthentication Providers,即如下所示:

    如截图所示那样,启用了FBA之后,需要我们提供自定义的Menbership Provider和Role Provider。

    创建Membership Provider和Role Provider

    这儿我选择创建一个Class Library,当然你也可以直接创建一个SharePoint 2013 Empty Project,注意不管是哪种,最终都需要把Assembly 注册/安装 到GAC里

    • 如果是创建了SharePoint Project,要安装Assembly到GAC,直接部署就行。
    • 如果是创建了Class Library,需要有两个步骤1).Sign the assembly(右键项目-àProperty-àSigning),2)gacutil /i "<assembly path/assembly name.dll>",如下所示(使用VS Command Tool):

    获取Strong Name Key File

    安装Assembly到GAC

    对于.NET 4.0以上的Assembly,GAC位于C:WindowsMicrosoft.NETassembly。.NET 3.5 GAC在C:Windowsassembly,所以别找错地方。Assembly成功注册到GAC后,最好IISReset下。

    接着,创建相关的Provider,分别继承MembershipProvider和RoleProvider即可。

    •  自定义MembershipProvider,主要代码如下:
    • 自定义Role Provider,如下所示:
    • 自定义的Provider成功安装到GAC之后,接着修改web.config。注意需要修改3个地方,Web Application Config、SharePoint Central Administration Config、SecurityTokenServiceApplication,其路径如果记不住的话,打开IIS,浏览即可,即如下所示:

    修改Web Config

    Web Config需要Assembly的Public Key Token,可以使用VS Command Tool来获取:

    • 首先修改Web Application的Web Config,找到其Membership节点,将以下代码复制进:
    复制代码
     <membership defaultProvider="i">
          <providers>
            <add name="i" type="Microsoft.SharePoint.Administration.Claims.SPClaimsAuthMembershipProvider, Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
            <add name="CustomMembershipProvider" type="Eyes.CustomProvider.FBA_CustomRoleProvider,Eyes.CustomProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c4a0ffa664cbc06c" />
          </providers>
        </membership>
        <roleManager defaultProvider="c" enabled="true" cacheRolesInCookie="false">
          <providers>
            <add name="c" type="Microsoft.SharePoint.Administration.Claims.SPClaimsAuthRoleProvider, Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
            <add name="CustomRoleProvider" type="Eyes.CustomProvider.FBA_CustomMembershipProvider,Eyes.CustomProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c4a0ffa664cbc06c" />
          </providers>
        </roleManager>
    复制代码
    • 接着修改SharePoint Central Administration的Web Config,
    复制代码
    <membership defaultProvider="i">
          <providers>
            <add name="i" type="Microsoft.SharePoint.Administration.Claims.SPClaimsAuthMembershipProvider, Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
            <add name="CustomMembershipProvider" type="Eyes.CustomProvider.FBA_CustomRoleProvider,Eyes.CustomProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c4a0ffa664cbc06c" />
          </providers>
        </membership>
        <roleManager>
          <providers>
            <add name="c" type="Microsoft.SharePoint.Administration.Claims.SPClaimsAuthRoleProvider, Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
            <add name="CustomRoleProvider" type="Eyes.CustomProvider.FBA_CustomMembershipProvider,Eyes.CustomProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c4a0ffa664cbc06c" />
          </providers>
        </roleManager>
    复制代码
    • 然后修改SecurityTokenSeriveApplication的Web Config,
    复制代码
    <system.web>
         <membership defaultProvider="i">
          <providers>
            <add name="i" type="Microsoft.SharePoint.Administration.Claims.SPClaimsAuthMembershipProvider, Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
            <add name="CustomMembershipProvider" type="Eyes.CustomProvider.FBA_CustomRoleProvider,Eyes.CustomProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c4a0ffa664cbc06c" />
          </providers>
        </membership>
        <roleManager defaultProvider="c" enabled="true" cacheRolesInCookie="false">
          <providers>
            <add name="c" type="Microsoft.SharePoint.Administration.Claims.SPClaimsAuthRoleProvider, Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
            <add name="CustomRoleProvider" type="Eyes.CustomProvider.FBA_CustomMembershipProvider,Eyes.CustomProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c4a0ffa664cbc06c" />
          </providers>
        </roleManager>
      </system.web>
    复制代码
    • 最后将Web Application的Authentication Type修改为混合模式,如下所示

    分配用户并测试

    成功为Web Application创建了自定义的Provider之后,接着就是测试是否成功。如添加访问用户,可以如下图操作所示:

    搜索用户,如下图所示:

    访问Site,提示混合登录模式,如下图所示:

    登录成功后显示信息:

    小结

    当以Windows Authentication注销时,会发生错误(查阅日志后报错信息encodeValue不能为空)。我猜是没清理Session,查了很多资料,发现这是个别现象。不知道最新的SharePoint 2013 Updates有没有解决这个问题。我的版本是SharePoint 2013 Server(原始版本,从未更新过)。如果解决的话,劳烦各位朋友告诉我一下。点击代码下载
