单点登录CAS与LDAP整合的实现

单点登录CAS与LDAP整合的实现单点登录（Single Sign-On，SSO）是一种身份验证和访问控制机制，允许用户使用一组凭据（如用户名和密码）登录到一个应用程序，然后在登录后访问其他应用程序而无需再次提供凭据。

这种机制的实现需要集成不同的身份验证系统，例如，CAS（Central Authentication Service）与LDAP（Lightweight Directory Access Protocol）。

CAS是一种基于Web的身份验证协议，它提供了一种单点登录解决方案，允许用户在一次登录后访问多个Web应用程序，并且不需要再次输入凭据。

CAS通过提供一个认证服务器来实现这一功能，该服务器负责验证用户的凭据，并生成一个票据（Ticket）以表示用户的身份。

LDAP是一种用于访问和维护分布式目录信息服务（Directory Information Services）的协议。

目录服务用于存储和组织用户和组的信息，包括用户名、密码和其他属性。

LDAP提供了一种标准化的方式来查找、添加、修改和删除目录条目，提供了对用户身份信息的集中存储和访问。

要将CAS和LDAP整合，首先需要配置CAS服务器以使用LDAP作为其用户存储和验证机制。

下面是实现此集成的步骤：1. 配置LDAP服务器：首先，需要在LDAP服务器上创建一个目录以存储用户和组的信息。

可以使用开源的LDAP服务器，如OpenLDAP或Microsoft的Active Directory。

2.配置LDAP属性映射：CAS需要将LDAP中的用户属性映射到CAS的用户模型中。

这些属性包括用户名、密码、姓名、角色等。

需要根据LDAP服务器的架构和CAS的用户模型进行正确的属性映射。

3.配置LDAP身份验证器：CAS使用一个或多个身份验证器来验证用户的凭据。

应该配置一个LDAP身份验证器来使用LDAP服务器进行用户身份验证。

4.配置CAS服务器：在CAS服务器上，需要配置CAS以使用LDAP身份验证器进行用户身份验证。

Alfresco 安装与配置图解

Alfresco安装与配置图解Alfresco是一款开源的企业内容管理系统（ECM），为企业提供了日常的文档管理、工作流（可以和企业目前的OA协同接合使用）、工作记录管理、知识管理、网络内容管理、图片管理等多种功能，所以从功能山观看，相当于MS的sharepoint,目前alfresco 对于中文支持的比以前也有了相当的改进。

另外，它的架构非常的清晰，功能也比较的完整，非常适合中小型企业快速低成本的部署知识管理系统Alfresco架构简图1、安装Alfresco：我们这里选择suse企业版平台来安装alfresco 4/wiki/Download_Community_Edition下载最新版alfresco, 以前老版本在安装之前系统需配置好Mysql,Tomcat,JDK 环境，目前4的版本方便了许多。

首先执行alfresco-community-4.2.c-installer-linux-x64.bin文件。

开始使用，打开浏览器访问：http://localhost:8080/alfresco可以看到alfresco的主页，使用admin用户及前面设定的密码能够正常登陆/opt/alfresco-4.0.a/manager-linux-x64.run在启动tomcat时候出现"tomcat could not be started"我们需要输入下面命令#rm /opt/alfresco-4.0.a/tomcat/temp/catalina.pid2、汉化配置/projects/zh-package/下载相应版本的汉化包unzip language_Pack.zipchmod +x install_language_pack.sh./ install_language_pack.shVim/opt/alfresco/tomcat/webapps/alfresco/WEB-INF/classes/alfresco/web-client-config.xml添加登陆页面的中文语言选项，然后找到<languages> 节点，再添加一行：<language locale="zh_CN">Chinese (Simplified)</language> 最后保存退出。

CAS客户端服务器端配置步骤

CAS客户端服务器端配置步骤CAS（Central Authentication Service）是一种Web单点登录协议，允许用户在一次登录后访问多个应用程序。

CAS客户端和服务器端的配置步骤通常包括以下几个方面：一、CAS客户端配置步骤：1.引入CAS客户端依赖。

首先需要在应用程序的构建配置文件中引入CAS客户端的依赖关系，以便在应用程序中使用CAS客户端的功能。

2.配置CAS客户端。

在应用程序的配置文件中添加CAS客户端的相关配置项，包括CAS服务器的地址、端口、协议类型等。

3.设置应用程序的登录认证方式为CAS客户端。

通过配置应用程序的认证方式为CAS客户端，可以将用户的登录认证转交给CAS服务器处理。

4.配置CAS客户端认证过滤器。

CAS客户端通常会提供一个认证过滤器，用于拦截用户的请求并进行认证处理。

配置认证过滤器的URL模式以及其他参数，以确保认证过程正确执行。

5.编写CAS客户端回调处理逻辑。

当用户在CAS服务器上成功登录后，CAS服务器会将用户重定向回客户端应用程序，并在URL中添加一个包含用户信息的票据参数。

客户端应用程序需要编写相应的回调处理逻辑，以解析该票据参数并进行相关的用户信息处理。

二、CAS服务器端配置步骤：1.安装和配置CAS服务器。

首先需要在服务器上安装CAS服务器，并使用CAS服务器提供的配置文件对服务器进行配置。

配置项包括CAS服务器的地址、端口、协议类型等。

2.配置CAS服务器的用户认证源。

CAS服务器通常需要与一个或多个用户认证源（如LDAP、数据库等）进行集成，以验证用户的用户名和密码。

配置CAS服务器与用户认证源的相关参数，确保用户可以被正确认证。

3.配置CAS服务器的服务清单。

在CAS服务器上配置服务清单，即允许用户访问的应用程序列表。

可以指定应用程序的URL地址、安全策略等信息。

4.配置CAS服务器的票据生成和验证方式。

CAS服务器会生成一个票据（Ticket）并返回给客户端应用程序，客户端应用程序在后续请求中需要解析和验证该票据。

３．设置流转规则：根据流程的逻辑关系，设置流程的流转规则，包括前一个任务节点的结束条件、后一个任务节点的触发条件等。

４．配置表单：为每个任务节点配置相应的表单，表单的内容可以根据实际需求进行定制。

５．部署流程：将设计好的流程部署到Alfresco服务器上，并启动流程实例。

６．测试流程：通过模拟实际业务场景，测试流程是否符合预期，并对不符合预期的地方进行调整和优化。

７．发布流程：经过测试和验证后，将流程正式发布到生产环境中，供实际业务使用。

Alfresco支持LDAP验证

Alfresco支持LDAP验证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/afres coNtlm/alfrescoNtlm1tomcat/webapps/alfresco/WEB-INF/classes/alfresco/extension/subsystems/Authentication/pass thru/passthru1tomcat/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.:alfrescoNtlm ldap-ad passthru./alfrescoNtlm:alfrescoNtlm1./alfrescoNtlm/alfrescoNtlm1:alfresco-authentication.properties ntlm-filter.properties./ldap-ad:ldap1./ldap-ad/ldap1:ldap-ad-authentication.properties./passthru:passthru1./passthru/passthru1:ntlm-filter.properties passthru-authentication-context.propertiesalfrescoNtlmntlm-filter.propertiesntlm.authentication.sso.enabled=falsentlm.authentication.mapUnknownUserToGuest=falsentlm.authentication.browser.ticketLogons=truealfresco-authentication.propertiesalfresco.authentication.allowGuestLogin=falsealfresco.authentication.authenticateCIFS=falsepassthruntlm-filter.propertiestlm.authentication.sso.enabled=false^Mntlm.authentication.mapUnknownUserToGuest=false^Mntlm.authentication.browser.ticketLogons=truepassthru-authentication-context.propertieseLocalServer=falsepassthru.authentication.domain= passthru.authentication.servers=192.168.1.5passthru.authentication.guestAccess=falsepassthru.authentication.defaultAdministratorUserNames=2023 #Timeout value when opening a session to an authentication server, in milliseconds passthru.authentication.connectTimeout=5000 #Offline server check interval in seconds passthru.authentication.offlineCheckInterval=300passthru.authentication.protocolOrder=NetBIOS,TCPIP passthru.authentication.authenticateCIFS=truepassthru.authentication.authenticateFTP=trueldap-adldap-ad-authentication.properties# This flag enables use of this LDAP subsystem for authentication.

Schedules must be kept up todate. The promised ship dates that you provide are visible for everyone at Scholastic.At the bottom, “Recent Receipts” will list all purchase order schedules received within the lastweek.Indicates a promisedship date is past dueNegotiations TabRequest for Quotation (RFQ) transactions that the supplier is involved in or is invited to by Scholastic. It provides a quick summary to easily monitor the status and responses.Request for Quote (RFQ)Receiving an Invite for a NegotiationThe Scholastic Sourcing group has the ability to invite vendors to bid on projects through theSupplier Portal. If your organization is invited to a negotiation, you will receive an email as well as a notification in the Supplier Portal.The email invitation will include a PDF overview of the project. There is also a link that will take you directly to the RFQ in the Supplier Portal.Viewing the RFQYou can view the RFQ by clicking on the link the email notification. Another option is to go to the Supplier Portal and navigate to the Negotiations tab. Click on the negotiation number inquestion.This will bring up the RFQ cover page with the time remaining to respond displayed. On the left hand side of the RFQ, you will see links to the different components of the RFQ.Click on the Overview link. This will bring up the Overview page, which has key dates tied to the RFQ. On the right hand side, you will find attachments to the RFQ. The attachment will have the requirements for the RFQ along with instructions, quantities, and any other relevant information.Click on the Lines link. This will bring up the line items tied to the RFQ. In some cases, due to complex requirements, there will be one placeholder line visible with the advanced requirements included in an attachment.Creating a ResponseWhen you decide to bid on an RFQ, you must first acknowledge that you will participate. You can do this from the Negotiations dashboard by scrolling to the “Open Invitations” section. Highlight the negotiation, and click on the Acknowledge Participation button.This will bring up the Acknowledge Participation popup. You can select Yes or No, and enter a comment to the Scholastic buyer.At this point, if you refresh the Negotiations dashboard, you will see YES listed in the ‘Will Participate’ column. You can create your response by highlighting the Negotiation and clicking on the Create Response button.Another way to create a response is to open the RFQ and click on the Create Response button on the upper right hand sideThis will bring up the response page. Enter the quote expiration date, an internal quote number if you have one, and any notes to the buyer. You can also attach any correspondence by clicking on the + sign next to Attachments.You can attach more than one file by clicking on the + sign.Once you attach a file, it will show up on the main screen. You can remove the attachment by clicking on the X next to the file name. Hit Save and then Next.This will bring you to the “Lines” screen. Enter unit costs for the lines along with a Promised Ship Date.For most negotiations, the Scholastic buyer will give the supplier an option to create your own line by clicking on the + sign under Create Alternate. This is especially useful if you want to incorporate a unique idea or proposal.On the Alternate Line screen, you are required to enter a description, response price, and response quantity. You can enter a note to the buyer and also attach files to the alternate line.After hitting Save and Close, the alternate line will be added to the RFQ response.Hit Save and Next.

目前单点登录主要基于Web的多种应用程序，即通过浏览器实现对多个B/S架构应用的统一账户认证。

2 CAS2.1 JA-SIG（CAS）的设计愿景CAS（Central Authentication Service – 中心认证服务）的目的就是使分布在一个企业内部各个异构系统的认证工作集中在一起，通过一个公用的认证系统统一管理和验证用户的身份。

在CAS上认证的用户将获得CAS颁发的一个证书，使用这个证书，用户可以在承认CAS证书的各个系统上自由穿梭访问，不需要再次的登录认证。

打个比方：对于加入欧盟的国家而言，在他们国家中的公民可以凭借着自己的身份证，在整个欧洲旅行，不用签证。

对于企业内部系统而言，CAS就是这个颁发欧盟认证的系统，其它系统都是加入欧盟的国家，它们要共同遵守和承认CAS的认证规则。

ssocas 原理

ssocas 原理
SSO（Single Sign On）即单点登录，是一种企业业务整合的解决方案，允许用户在多个应用系统中只需登录一次，就可以访问所有相互信任的应用系统。

CAS（Central Authentication Service）是一款为Web应用提供单点登录的开源框架。

CAS包含两个主要部分：
1.CAS Server：负责完成对用户的认证工作，需要独立部署，并处理用户名、密
码等凭证（Credentials）。

2.CAS Client：负责处理对客户端受保护资源的访问请求，当需要对请求方进行
身份认证时，它会重定向到CAS Server进行认证。

一旦认证成功，CAS Server会将用户名和密码放到session中，并添加一个证据，然后跳转到系统的主界面。

此后，客户端应用不再接受任何的用户名密码等Credentials。

CAS最基本的协议过程如下：
1.第一次登录系统，用户打开浏览器，通过地址请求受保护的资源。

2.CAS客户端会把请求自动的重定向到CAS服务器端。

3.CAS服务器端发现没有证据，就直接把CAS服务器的登录界面转到浏览器，
呈现给用户。

4.用户输入用户名和密码进行验证。

5.验证成功，CAS服务器会把用户名和密码放到session中，并添加一个证据，
然后跳转到系统的主界面。

通过这种方式，CAS实现了单点登录功能，简化了用户在多个系统之间的登录过程，提高了效率和便利性。

请注意，以上内容仅供参考，如需更详细的信息，建议查阅相关文献或咨询专业技术人员。

ldap 认证过程 -回复

ldap 认证过程-回复LDAP（Lightweight Directory Access Protocol）是一种轻量级目录访问协议，它用于在网络上访问和管理分布式目录服务。

LDAP常用于实现用户认证和授权，以及管理组织中的用户和资源。

LDAP认证过程是指用户使用LDAP协议来验证其身份的过程。

下面将一步一步地回答关于LDAP认证过程的问题，以帮助我们更好地理解。

第1步：建立连接首先，客户端需要使用LDAP API连接到LDAP服务器。

LDAP服务器通常使用标准的LDAP端口（389）进行监听。

客户端可以使用LDAP URL （例如ldap:example:389）来指定要连接的服务器地址和端口。

第2步：身份识别在建立连接后，客户端需要向服务器发送绑定请求，以提供其身份信息进行身份验证。

绑定请求包括以下信息：- 绑定DN（Distinguished Name）：一个唯一标识用户的LDAP路径（例如uid=johndoe,ou=users,dc=example,dc=com）。

- 绑定密码：与绑定DN关联的密码。

第3步：认证验证服务器接收到绑定请求后，在LDAP目录中查找与提供的DN匹配的条目，并比较提供的密码与存储在目录中的密码是否匹配。

如果密码匹配，服务器将返回一个绑定成功的响应，并将客户端标识为已经通过身份验证的用户。

第4步：访问授权一旦用户通过身份验证，服务器将根据用户的身份和权限对其进行授权。

在LDAP目录中，授权通常使用访问控制列表（ACLs）来定义，ACLs定义了用户或用户组对特定目录条目的访问权限。

第5步：执行操作绑定成功后，客户端可以使用LDAP协议执行各种操作，如搜索（查询）目录、添加、修改或删除目录项等。

每个操作都需要提供相应的身份验证信息，以确保用户具有执行该操作所需的适当权限。

第6步：终止连接当客户端完成操作后，或不再需要与LDAP服务器进行通信时，它可以使用LDAP API关闭连接并终止与服务器的通信。

是新手入门的一个教程。

二、LDAP简介2.1 LDAP介绍LDAP的英文全称是Lightweight Directory Access Protocol，它是基于X.500标准的，但是简单多了并且可以根据需要定制。

与X.500不同，LDAP支持TCP/IP，这对访问Internet是必须的。

LDAP的核心规范在RFC 中都有定义，所有与LDAP相关的RFC都可以在LDAPman RFC网页中找到。

LDAP目录中可以存储各种类型的数据：电子邮件地址、邮件路由信息、人力资源数据、公用密匙、联系人列表，等等。

通过把LDAP目录作为系统集成中的一个重要环节，可以简化员工在企业内部查询信息的步骤，甚至连主要的数据源都可以放在任何地方。

2.2 LDAP优劣目录服务的数据类型主要是字符型，为了检索的需要添加了BIN（二进制数据）、CIS（忽略大小写）、CES（大小写敏感）、TEL（电话型）等语法（Syntax），而不是关系数据库提供的整数、浮点数、日期、货币等类型，同样也不提供象关系数据库中普遍包含的大量的函数，它主要面向数据的查询服务（查询和修改操作比一般是大于10:1），不提供事务的回滚（rollback）机制，它的数据修改使用简单的锁定机制实现All-or-Nothing，它的目标是快速响应和大容量查询并且提供多目录服务器的信息复制功能。
