NTLM authentication config for Share 3.4

Hi,I recently implemented the alfresco 3.4 version to make test.I don't arrive to configure share to do NTLM authentication, i try to do the same configuration than the 3.3, but it seems it doesn't work. SSO is enable for passthru systems and i edited web.xml and share-config-custom.xml, after i can

Hi,

The web-tier SSO filters were refactored in 3.4 - so instead of multiple filters (NTLM, Kerberos etc.) that you previously enabled in web.xml, there is now a single SSO filter that controls all.
It also means that you no longer need to edit web.xml - infact you should revert your changes. It should look like this:


   <filter>
      <description>Share SSO authentication support filter.</description>
      <filter-name>Authentication Filter</filter-name>
      <filter-class>org.alfresco.web.site.servlet.SSOAuthenticationFilter</filter-class>
      <init-param>
         <param-name>endpoint</param-name>
         <param-value>alfresco</param-value>
      </init-param>
   </filter>
   
   <filter-mapping>
      <filter-name>Authentication Filter</filter-name>
      <url-pattern>/page/*</url-pattern>
   </filter-mapping>
   
   <filter-mapping>
      <filter-name>Authentication Filter</filter-name>
      <url-pattern>/p/*</url-pattern>
   </filter-mapping>
   
   <filter-mapping>
      <filter-name>Authentication Filter</filter-name>
      <url-pattern>/proxy/*</url-pattern>
   </filter-mapping>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

the filter is "always on" and automatically routes NTLM etc. if Share is configured to use it, so the share-config-custom.xml configuration is the same, i.e. you need to enable this section:


   <config evaluator="string-compare" condition="Remote">
      <remote>
         <connector>
            <id>alfrescoCookie</id>
            <name>Alfresco Connector</name>
            <description>Connects to an Alfresco instance using cookie-based authentication</description>
            <class>org.springframework.extensions.webscripts.connector.AlfrescoConnector</class>
         </connector>

         <endpoint>
            <id>alfresco</id>
            <name>Alfresco - user access</name>
            <description>Access to Alfresco Repository WebScripts that require user authentication</description>
            <connector-id>alfrescoCookie</connector-id>
            <endpoint-url>http://localhost:8080/alfresco/wcs</endpoint-url>
            <identity>user</identity>
            <external-auth>true</external-auth>
         </endpoint>
      </remote>
   </config>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

and that's it! I will update the wiki appropriately now.

I have updated the wiki: http://wiki.alfresco.com/wiki/Alfresco_Authentication_Subsystems#Alfresco_Share_SSO_using_NTLM

Sorry for the confusion! But hopefully it is better now you do not need to edit web.xml.

Re: NTLM authentication config for Share 3.4

kevinr — Wed, 03 Nov 2010 13:47:20 GMT

The web.xml is missing this filter-mapping (bug fix - will be present in 3.4.b Community release due next week):

   <filter-mapping>
      <filter-name>Authentication Filter</filter-name>
      <url-pattern>/proxy/*</url-pattern>
   </filter-mapping>‍‍‍‍

However the reason it is not working at all: you need to remove this block from the Remote section lower down in your config:

         <endpoint>
            <id>alfresco</id>
            <name>Alfresco - user access</name>
            <description>Access to Alfresco Repository WebScripts that require user authentication</description>
            <connector-id>alfresco</connector-id>
            <endpoint-url>http://localhost:8080/alfresco/s</endpoint-url>
<identity>user</identity>
         </endpoint>‍‍‍‍‍‍‍‍

Otherwise you are effectively overriding the same value twice i.e. the alfresco endpoint is overridden once to enable NTLM, then you override it again later in the config file. I assume you should also update the endpoint-url values remaining in that section to t-alfresco:8080.

Hi guys,
I have a problem… I've setup my environment exactly as explained here but when Alfresco Share is loaded nothing appears, a blank page is flushed.

I've indeed successfully configured Alfresco Explorer (/alfresco) with external authentication and X-Alfresco-Remote-User, now I'd like to enable the same for Share, is there anything I can do? Is correct to sort out the NTLM configuration or I completely misunderstood wiki?

I hope someone can help me,

Thanks,

N.
