Active Directory LDAP Sync

[daveram]

G'day,

I've setup Alfresco 3.2 with passthru authentication easily enough, however what I'm banging my head on is AD synchronization.  This setup is on a Win2k3 server and trying to authorize to a Win2k3 domain controller.  Global config file as follows:

authentication.chain=alfrescoNtlm1:alfrescoNtlm,passthru1:passthru,ldap-ad:ldap1


ntlm.authentication.sso.enabled=true
passthru.authentication.authenticateCIFS=true

passthru.authentication.domain=DOMAIN
passthru.authentication.servers=server1,server2

ldap.authentication.active=false
ldap.synchronization.active=true

ldap.authentication.userNameFormat=%s@domain.com
ldap.authentication.java.naming.provider.url=ldap://server1:389

ldap.authentication.defaultAdministratorUserNames=administrator,myaccount

ldap.synchronization.java.naming.security.principal=serviceaccount@domain.com
ldap.synchronization.java.naming.security.credentials=<secret>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

What seems to be happening is I'm getting a login failed error in the log, as such:

18:21:48,819 INFO  [org.alfresco.repo.management.subsystems.ChildApplicationContextFactory] Starting 'Authentication' subsystem, ID: [managed, passthru1]

org.alfresco.web.scripts.WebScriptException: 06240087 Login failed‍‍‍‍‍‍‍‍

Any ideas as to what might be causing this?  I'm seeing network traffic on a packet capture talking to the DC, but that's it.

In my experience your config shouldn't work for passthru since alfrescoNtlm and passthru shouldn't be enabled to provide sso at the same time (which is what you setup). So while your CIFS auth might work in this example, I doubt that you can succesfully login to /alfresco webapp with your AD credentials using passthru because in your case sso auth is handled by alfrescoNtlm.

You need to acquire the 14.07.2009. nightly build of Alfresco to get the version with working extensions/classpaths. And then you need to define separate configuration for different instances of your Authentication subsystem as per http://wiki.alfresco.com/wiki/Alfresco_Subsystems#Configuring_Subsystems.

This was recently explained to me so search for my posts on this forum, and you can also find the link to the build in the discussion.

As for  need to provide search base additional to what you provided. Here is my $TOMCAT_HOME/shared/classes/alfresco/extensions/subsystems/Authentication/ldap-ad/ldap-ad1/ldap-ad.properties

ldap.authentication.userNameFormat=%s@<myDomain.tld>
ldap.authentication.java.naming.provider.url=ldap://<myDC'sFQDN>:389

ldap.authentication.defaultAdministratorUserNames=administrator,<me>

ldap.synchronization.java.naming.security.principal=administrator@<myDomain.tld>
ldap.synchronization.java.naming.security.credentials=<password>

ldap.authentication.java.naming.security.authentication=SIMPLE

ldap.synchronization.userSearchBase=ou=<OUcontainingUsers>,dc=<myDomain>,dc=<tld>

ldap.synchronization.groupSearchBase=ou=<OUcontainingUsers>,dc=<myDomain>,dc=<tld>

ldap.authentication.allowGuestLogin=true
synchronization.synchronizeChangesOnly=false
synchronization.syncWhenMissingPeopleLogIn=true
synchronization.autoCreatePeopleOnLogin=true

It also looks like the line

authentication.chain=alfrescoNtlm1:alfrescoNtlm,passthru1assthru,ldap-ad:ldap1

is wrong. Make it "ldap1:ldap-ad" instead.
