Hello,I'm currently working with Alfresco 4.2.c Community and I am trying to obtain authentication within Alfresco through our LDAP AD. After many searches on the net I was able to throw together a configuration and all of my AD users have appeared within alfresco (stack trace below) and there are n

I should also say that I'm using bitnami alfresco stack and here is yesterday's log when my users were actually pulled into alfresco.

Okay I ended up getting it working.

I did not have passthru enabled or configured so it was only trying to authenticate my ldap users from Alfresco and not my AD server. Added the following config settings…

authentication.chain=alfinst:alfrescoNtlm,ldap1:ldap-ad,passthru1assthru (appended passthru)
passthru.authentication.servers=DOMAIN\\batman.robin.com,batman.com
passthru.authentication.domain=#leave blank
passthru.authentication.guestAccess=false

Restarted Tomcat and was able to login as myself using my AD credentials… woohoo

Hi m4lewis,

Congratz for getting it to work.
And thanks for posting the answer for everyone to see.

However, I'm sorry to be the bearer of bad news but it looks like you have a security hole there.
With simple authentication and ldap without SSL, your password will transit on your network in the clear:
(cf:http://wiki.alfresco.com/wiki/Alfresco_Authentication_Subsystems#Configuration_2)

So the next step before going to production might be to either put your ldap behind SSL or use DIGEST-MD5 and configure your LDAP with reversible encryption.

Good luck!
