hi,

I'm having the same problem and I also can't sync the users, when I try to login into alfresco, it shows that the user is Unable to login - unknown username/password.
I've changed the properties according to the documentation, but it just don't work.
Does anyone know what could be wrong??

Thanks in advance.

Hopefully someone will see this and offer some help, since it tells me I cannot start my own thread.

Basically, using the 5.0 build, I can't seem to get LDAP Sync or Passthru to work.

It seems to be authenticating users from AD, but no info syncs, and the error in the log is not very helpful.

I've done a lot of searches thru the forms, and the biggest issue I'm finding is that there's seems to be no one single 'How-To' for AD. I find suggestions that offer suggestions in direct conflict with other's directions, or are done in what seems to be a completely different manner, and the bulk of the results of my searches are for older versions, and not 5.x

Here's my global config, covering the entire Auth configuration. I've substituted the domain HELPME for my actual domain. I realize this looks very bloated, but this is putting together everyone's suggestion for why it's not working, as found in other's posts asking for help:

I have verified that the AD/LDAP account 'alfresco' can read/view any user in AD using the tool Softerra LDAP Browser 4.5, and the account can fully roam the AD. It is a member of 'Domain Users' only.

When the app is started, I'm presented with the login prompt, so Passthru isn't working.

I can enter my AD ID/PW and it does log me in, but all profile info is blank, and of course it shows my login ID and not my common name.

This is the error / reason in the log when AD Sync tries to kick in:

Seems like your first error is:


2015-12-24 00:23:52,504 ERROR [org.alfresco.repo.security.sync.ChainingUserRegistrySynchronizer] [localhost-startStop-1] Synchronization aborted due to error
org.alfresco.error.AlfrescoRuntimeException: 11240001 Error during LDAP Search. Reason:org:389

Caused by: javax.naming.CommunicationException: org:389 [Root exception is java.net.UnknownHostException: org]
‍‍‍‍‍‍

In case it's a hostname/DNS lookup issue, have you tried using an IP address rather than the FQDN here?


ldap.authentication.java.naming.provider.url=ldap://SVR-001-DC01.HELPME.org:389

jjscampos, your filter looks like it's missing a closing ")", as well as the "\" to escape the "="


ldap.synchronization.personQuery=(&(objectclass=user)
‍‍‍

And assuming you intentionally want to leave out the clause which excludes AD users who are not active, then you can/should remove the remaining "&". So it should just look like this:


ldap.synchronization.personQuery=(objectclass\=user)

dgcupit, your error seems to be "UnknownHostException":


2015-12-24 00:23:52,504 ERROR [org.alfresco.repo.security.sync.ChainingUserRegistrySynchronizer] [localhost-startStop-1] Synchronization aborted due to error

Caused by: java.net.UnknownHostException: org
‍‍‍‍‍‍‍‍

Have you tried using an IP address here, in case it's a hostname/DNS lookup issue? e.g. if the IP for your LDAP server is 10.10.10.1:


ldap.authentication.java.naming.provider.url=ldap://10.10.10.1:389
