Active Directory group sync not working

akhan

I followed the example on http://www.anotherstrangerme.com/alfresco-integration-with-active-directory/ to setup authentication and ldap/ad sync. Authentication (using NTLM) is working fine but I am not seeing any group information from AD. I am trying map some AD groups to Alfresco groups and assign space permission to the group. I have enable debugging for log4j.logger.org.alfresco.repo.security.* and not seeing any issues.

Please help.

Thanks and regards,
AK

Well for start your group and user queries are wrong. In AD lets say that you want to import all groups that are member of "Alfresco Groups" group you'd use something like this:

ldap.synchronization.groupQuery=(&(objectclass=group)(memberOf=CN\=Alfresco Groups,CN\=Users,DC\=myorg,DC\=ca,DC\=us))‍

To import all groups in AD use just:

ldap.synchronization.groupQuery=(objectclass=group)‍

To import all groups from some OU then use the above query but narrow down the groupSearchBase.

Same rules apply for users. I suggest using a tool like SysInternals ADExplorer that shows you alot more useful information to build proper queries.

akhan

I think the query should be fine since I have used it in other systems. I am not seeing any errors! And I am not seeing any of the AD groups.

ivan_plestina

Well, to prove you wrong why don't you try setting the following:

ldap.synchronization.personQuery=(objectclass=user)
ldap.synchronization.groupQuery=(objectclass=group)‍‍

And then do the full sync…

You're not seeing any errors because you can put anything in your LDAP query but what yours return is simply an empty set because it's not good.

micdy

Ok, i think i start to anderstand.

so if i want to select all users who are in group : my_employees

ldap.synchronization.personQuery=(&(objectclass=user)(memberOf=CN\=my_employee,CN\=Users,DC\=metal_org,DC\=com))
‍‍‍

is that rite?
because it dont work for me

You are confusing groups with organizational units (OUs). Group and User distinguished names (DNs) are organized in a tree structure containing the names of various OUs and domain components (DCs).

To restrict the user and group search to specific OUs, you must include these in groupSearchBase and userSearchBase. These "SearchBase" attributes are simply the DN suffix that should be common to all members.

So the only attributes you would have to change would be these (just remove or comment out all the rest to get sensible defaults)

ldap.authentication.active=false
ldap.authentication.java.naming.provider.url=ldap://206.x.x.x:389
ldap.synchronization.java.naming.security.principal=CN\=Alfresco User,CN\=Users,DC\=myorg,DC\=ca,DC\=us
ldap.synchronization.java.naming.security.credentials=password
ldap.synchronization.groupSearchBase=DC=\myorg,DC\=ca,DC\=us
ldap.synchronization.userSearchBase=DC=\myorg,DC\=ca,DC\=us

Now if you really want to restrict it to only the users in a certain group (rather than a certain OU) whose full DN is CN\=my_employee,CN\=Users,DC\=metal_org,DC\=com you can use memberof, but remember to extend the differentialquery too!

ldap.synchronization.personQuery=(&(objectclass\=user)(memberOf=CN\=my_employee,CN\=Users,DC\=metal_org,DC\=com)(userAccountControl\:1.2.840.113556.1.4.803\:\=512))
ldap.synchronization.personDifferentialQuery=(&(objectclass\=user)(memberOf=CN\=my_employee,CN\=Users,DC\=metal_org,DC\=com)(userAccountControl\:1.2.840.113556.1.4.803\:\=512)(!(modifyTimestamp<\={0})))

ldap.synchronization.groupQuery=(&(objectclass\=group)(CN\=my_employee))
ldap.synchronization.groupDifferentialQuery=(&(objectclass\=group)(CN\=my_employee)(!(modifyTimestamp<\={0})))

Wow, thanks, now i anderstand querry better, and i really only have the users i want to

thank you
