I'm trying to configure Alfresco to authenticate via our eDirectory server.  I copied the ldap-authentication-context.xml.sample to /WEB-INF/classes/alfresco/extension and made the changes shown below:


<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>

    <!– DAO that rejects changes - LDAP is read only at the moment –>

    <bean id="alfDaoImpl" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
        <property name="proxyInterfaces">
            <value>org.alfresco.repo.security.authentication.MutableAuthenticationDao</value>
        </property>
                <property name="transactionManager">
                        <ref bean="transactionManager" />
                </property>
                <property name="target">
                        <bean class="org.alfresco.repo.security.authentication.ntlm.NullMutableAuthenticationDao" />
                </property>
                <property name="transactionAttributes">
                <props>
                        <prop key="*">${server.transaction.mode.default}</prop>
                </props>
                </property>
        </bean>

    <!– LDAP authentication configuration –>

    <!–

    You can also use JAAS authentication for Kerberos against Active Directory or NTLM if you also require single sign on from the
    web browser. You do not have to use LDAP authentication to synchronise groups and users from an LDAP store if it supports other
    authentication routes, like Active Directory.

    –>

    <bean id="authenticationComponentImpl" class="org.alfresco.repo.security.authentication.ldap.LDAPAuthenticationComponentImpl">
        <property name="LDAPInitialDirContextFactory">
            <ref bean="ldapInitialDirContextFactory"/>
        </property>
        <property name="userNameFormat">
            <!–

            This maps between what the user types in and what is passed through to the underlying LDAP authentication.

            "%s" - the user id is passed through without modification.
            Used for LDAP authentication such as DIGEST-MD5, anything that is not "simple".

            "cn=%s,ou=London,dc=company,dc=com" - If the user types in "Joe Bloggs" the authentricate as "cn=Joe Bloggs,ou=London,dc=company,dc=com"
            Usually for simple authentication.

            –>
            <value>%s</value>
        </property>
    </bean>

    <!–

    This bean is used to support general LDAP authentication. It is also used to provide read only access to users and groups
    to pull them out of the LDAP reopsitory

    –>

    <bean id="ldapInitialDirContextFactory" class="org.alfresco.repo.security.authentication.ldap.LDAPInitialDirContextFactoryImpl">
        <property name="initialDirContextEnvironment">
            <map>
                <!– The LDAP provider –>
                <entry key="java.naming.factory.initial">
                    <value>com.sun.jndi.ldap.LdapCtxFactory</value>
                </entry>

                <!– The url to the LDAP server –>
                <!– Note you can use space separated urls - they will be tried in turn until one works –>
                <!– This could be used to authenticate against one or more ldap servers (you will not know which one ….) –>
                <entry key="java.naming.provider.url">
                    <value>ldap://LDAP_SERVER:389</value>
                </entry>

                <!– The authentication mechanism to use      –>
                <!– Some sasl authentication mechanisms may require a realm to be set –>
                <!–                java.naming.security.sasl.realm –>
                <!– The available options will depend on your LDAP provider –>                <entry key="java.naming.security.authentication">
                    <value>DIGEST-MD5</value>
                </entry>

                <!– The id of a user who can read group and user information –>
                <!– This does not go through the pattern substitution defined above and is used "as is" –>
                <entry key="java.naming.security.principal">
                    <value>cn=LOGIN,ou=its,ou=admn,o=HCNET</value>
                </entry>

                <!– The password for the user defined above –>
                <entry key="java.naming.security.credentials">
                    <value>PASSWORD</value>
                </entry>
            </map>
        </property>
    </bean>

    <!– Ldap Syncronisation support –>

    <!–

    There can be more than one stack of beans that import users or groups. For example, it may be easier
    to have a version of ldapPeopleExportSource, and associated beans, for each sub-tree of your ldap directory
    from which you want to import users. You could then limit users to be imported from two or more sub tress and ignore
    users found else where. The same applies to the import of groups.

    The defaults shown below are for OpenLDAP.

    –>


    <!– Extract user information from LDAP and transform this to XML –>

    <bean id="ldapPeopleExportSource" class="org.alfresco.repo.security.authentication.ldap.LDAPPersonExportSource">
        <!–
        The query to select objects that represent the users to import.

        For Open LDAP, using a basic schema, the following is probably what you want:
        (objectclass=inetOrgPerson)

        For Active Directory:
        (objectclass=user)
        –>
        <property name="personQuery">
            <value>(objectclass=inetOrgPerson)</value>
        </property>

        <!–
        The seach base restricts the LDAP query to a sub section of tree on the LDAP server.
        –>
        <property name="searchBase">
            <value>o=HCNET</value>
        </property>

        <!–
        The unique identifier for the user.

        THIS MUST MATCH WHAT THE USER TYPES IN AT THE LOGIN PROMPT

        For simple LDAP authentication this is likely to be "cn" or, less friendly, "distinguishedName"

        In OpenLDAP, using other authentication mechanisms "uid", but this depends on how you map
        from the id in the LDAP authentication request to search for the inetOrgPerson against which
        to authenticate.

        In Active Directory this is most likely to be "sAMAccountName"

        This property is mandatory and must appear on all users found by the query defined above.

        –>
        <property name="userIdAttributeName">
            <value>uid</value>
        </property>

        <!– Services –>
        <property name="LDAPInitialDirContextFactory">
            <ref bean="ldapInitialDirContextFactory"/>
        </property>
        <property name="personService">
            <ref bean="personService"></ref>
        </property>
        <property name="namespaceService">
            <ref bean="namespaceService"/>
        </property>

        <!–
        The path to the location of a space to use as the default home folder.
        This folder should be readable by all users, or a group to which all imported users belong.
        –>
        <property name="defaultHomeFolder">
            <value>/app:company_home</value>
        </property>

        <!–
        This property defines a mapping between attributes held on LDAP user objects and
        the properties of user objects held in the repository. The key is the QName of an attribute in
        the repository, the value is the attribute name from the user/inetOrgPerson/.. object in the
        LDAP repository.
        –>
        <property name="attributeMapping">
            <map>
                <entry key="cm:userName">
                    <!– Must match the same attribute as userIdAttributeName –>
                    <value>uid</value>
                </entry>
                <entry key="cm:firstName">
                    <!– OpenLDAP: "givenName" –>
                    <!– Active Directory: "givenName" –>
                    <value>givenName</value>
                </entry>
                <entry key="cm:lastName">
                    <!– OpenLDAP: "sn" –>
                    <!– Active Directory: "sn" –>
                    <value>sn</value>
                </entry>
                <entry key="cm:email">
                    <!– OpenLDAP: "mail" –>
                    <!– Active Directory: "???" –>
                    <value>mail</value>
                </entry>
                <entry key="cm:organizationId">
                    <!– OpenLDAP: "o" –>
                    <!– Active Directory: "???" –>
                    <value>o</value>
                </entry>
            </map>
        </property>
    </bean>

    <!– Extract group information from LDAP and transform this to XML –>

    <bean id="ldapGroupExportSource" class="org.alfresco.repo.security.authentication.ldap.LDAPGroupExportSource">
        <!–
        The query to select objects that represent the groups to import.

        For Open LDAP, using a basic schema, the following is probably what you want:
        (objectclass=groupOfNames)

        For Active Directory:
        (objectclass=group)
        –>
        <property name="groupQuery">
            <value>(objectclass=groupOfNames)</value>
        </property>

        <!–
        The seach base restricts the LDAP query to a sub section of tree on the LDAP server.
        –>
        <property name="searchBase">
            <value>dc=alfresco,dc=org</value>
        </property>

        <!–
        The unique identifier for the user. This must match the userIdAttributeName on the ldapPeopleExportSource bean above.
        –>
        <property name="userIdAttributeName">
            <value>uid</value>
        </property>

        <!–
        An attribute that is a unique identifier for each group found.
        This is also the name of the group with the current group implementation.
        This is mandatory for any groups found.

        OpenLDAP: "cn" as it is mandatory on groupOfNames
        Active Directory: "cn"

        –>
        <property name="groupIdAttributeName">
            <value>cn</value>
        </property>

        <!–
        The objectClass attribute for group members.
        For each member of a group, the distinguished name is given.
        The object is looked up by its DN. If the object is of this class it is treated as a group.
        –>
        <property name="groupType">
            <value>groupOfNames</value>
        </property>

        <!–
        The objectClass attribute for person members.
        For each member of a group, the distinguished name is given.
        The object is looked up by its DN. If the object is of this class it is treated as a person.
        –>
        <property name="personType">
            <value>inetOrgPerson</value>
        </property>
        <property name="LDAPInitialDirContextFactory">
            <ref bean="ldapInitialDirContextFactory"/>
        </property>
        <property name="namespaceService">
            <ref bean="namespaceService"/>
        </property>

        <!–
        The repeating attribute on group objects (found by query or as sub groups)
        used to define membership of the group. This is assumed to hold distinguished names of
        other groups or users/people; the above types are used to determine this.

        OpenLDAP: "member" as it is mandatory on groupOfNames
        Active Directory: "member"

        –>
        <property name="memberAttribute">
            <value>member</value>
        </property>

        <property name="authorityDAO">
            <ref bean="authorityDAO"/>

My service starts but does seem to authenticate what so ever.  Aside the the "file server is wrong authenticator" message I don't see anything wrong in the logs.  I am admittedly a beginner at Alfresco, am I missing something in my config file shown above?  Thanks

Hi linuxos77, I've tried to configure my Alfresco to use our eDir accounts too, but I can't find the file  ldap-authentication-context.xml.sample to begin with.
I'm using Alfresco Community 2.1, is this version support?
Is that file the only thing needed to authenticate to Alfresco using eDir?
Thank you!
