Alfresco 1.2.1 Active Directory Authentication

[hsantander]

Hi
I'm trying to set up the LDAP authentication procces. I follow the documente at wiki but I didn't get any results. When I set the log level to debug this is one of the messages I got:

18:08:45,183 DEBUG [transaction.interceptor.RuleBasedTransactionAttribute] Applying rules to determine whether transaction should rollback on org.alfresco.repo.security.authentication.AuthenticationException: LDAP authentication failed.

The configuration I use is the same of the authentication document at wiki, except that I don't configure user replication. My LDAP repository is Active Directory.

Any help?

Thanks

Hi again
Reading the post I reach this http://forums.alfresco.com/viewtopic.php?p=6416#6416. The user of this post seems to have the authentication working, so I create a new authentication-services-contex.xml same as the file in the post, with the modification of Active Directory parameters.
When I try to log in I got this error losg:

Hi

Can you confirm you can access the LDAP server using a well known client.
For example, the softerra LDAP browser.

What authentication mechanism are you using?
Are you sure your LDAP server supports the authentication mechanism?

Try kerberos authentication and confirm this works.

Regards

Andy

Hi
I use this Active Directory for squid authentication without any problem. I use ldapsearch to verify that the settings are correct. From the server where I have alfresco installed I make a bind and a search without problem.
Here is a fragment of authentication-services-context.xml where the ldap configuration it's defined:

    <bean id="ldapInitialDirContextFactory" class="org.alfresco.repo.security.authentication.ldap.LDAPInitialDirContextFactoryImpl">
        <property name="initialDirContextEnvironment">
             <map>
                <entry key="java.naming.factory.initial">
                    <value>com.sun.jndi.ldap.LdapCtxFactory</value>
                </entry>
                <entry key="java.naming.provider.url">
                    <value>ldap://a.b.c.d:389</value>
                </entry>
                <entry key="java.naming.security.authentication">
                    <value>simple</value>
                </entry>
                <entry key="java.naming.security.principal">
                    <value>CN=user_for_reading,OU=…,OU=…,OU=…,OU=…,DC=…,DC=…,DC=es</value>
                </entry>
                <entry key="java.naming.security.credentials">
                    <value>xxxxxx</value>
                </entry>
             </map>
        </property>
    </bean>

Hi,

What value did you use for the userNameFormat property in the authenticationComponentImpl bean?

–Aladdin

[hsantander]

Here is the configuration:

   <bean id="authenticationComponentImpl" class="org.alfresco.repo.security.authentication.ldap.LDAPAuthenticationComponentImpl">
        <property name="LDAPInitialDirContextFactory">
            <ref bean="ldapInitialDirContextFactory" />
        </property>
        <property name="userNameFormat">
            <value>sAMAccountName=%s</value>
        </property>
    </bean>

Thanks

Hi,

I use ldapsearch to verify that the settings are correct. From the server where I have alfresco installed I make a bind and a search without problem.

What is the Distinguished Name binddn (-D option) you use in the above mentioned ldapsearch command? Is it sAMAccountName=username?

Whatever it is must be the same string formatted in the userNameFormat property.

Cheers,

–Aladdin

Hi
I was out of the office and start again this morning.
You are right. I make a mistake thinking that userNameFormat refers to the attribute which stores the username. The problem now is tha my users are on different paths on the Active Directory (several OUs). I read about this in other post so I'm going to try now the JAAS authentication.

Thanks a lot.

[hsantander]

Now the problem arise with JAAS. I use the same server with Active Directory and with this configuration in authentication-services-context.xml where aa.bb.cc.dd is the IP of the server with Active Directory:

    <!– The authentication component.                                      –>

    <!– Jass authentication - most of the config goes somewhere else       –>

    <bean id="authenticationComponentImpl"
                 class="org.alfresco.repo.security.authentication.jaas.JAASAuthenticationComponent">
        <property name="realm">
            <value>aa.bb.cc.dd</value>
        </property>
        <property name="jaasConfigEntryName">
            <value>Alfresco</value>
        </property>
    </bean>

    <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 name="nodeService">
                    <ref bean="nodeService" />
                </property>
            </bean>
        </property>
        <property name="transactionAttributes">
            <props>
                <prop key="*">${server.transaction.mode.default}</prop>
            </props>
        </property>
    </bean>

The error I got when started the login proccess is:

Thanks

I make a mistake with the realm parameter. Now the value of this parameter is the name of my domain in uppercase, but I get the same error.

Any help? Thanks
