LDAP Synchronization with Alfresco 3.4d

[pnavinkumar]

Hi all

I am new to alfresco and I am trying to setup the LDAP Sync with 3.4d. I have been able to establish the login to my AD which is a win2003 server. But somehow synchronization doesn't seem to work for me.

Here is my configuration:

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

ldap.authentication.active=true
ldap.authentication.userNameFormat=%s
ldap.authentication.defaultAdministratorUserNames=admin
ldap.authentication.java.naming.provider.url=ldap://domainserver:389
ldap.authentication.java.naming.security.authentication=simple

ldap.synchronization.active=true
ldap.synchronization.java.naming.security.principal=ldap@itech.com
ldap.synchronization.java.naming.security.credentials=password

ldap.synchronization.groupQuery=(objectclass\=group)
ldap.synchronization.groupDifferentialQuery=(&(objectclass\=group)(!(modifyTimestamp<\={0})))
ldap.synchronization.personQuery=(objectclass\=inetOrgPerson)
ldap.synchronization.personDifferentialQuery=(&(objectclass\=inetOrgPerson)(!(modifyTimestamp<\={0})))
ldap.synchronization.groupSearchBase=ou\=Groups,dc\=itech,dc\=com
ldap.synchronization.userSearchBase=CN\=Users,dc\=itech,dc\=com
ldap.synchronization.modifyTimestampAttributeName=modifyTimestamp
ldap.synchronization.timestampFormat=yyyyMMddHHmmss'Z'

ldap.synchronization.userIdAttributeName=sAMAccountName
ldap.synchronization.userFirstNameAttributeName=givenName
ldap.synchronization.userLastNameAttributeName=sn
ldap.synchronization.userEmailAttributeName=mail
ldap.synchronization.userOrganizationalIdAttributeName=o
ldap.synchronization.defaultHomeFolderProvider=userHomesHomeFolderProvider
ldap.synchronization.groupIdAttributeName=cn
ldap.synchronization.groupType=groupOfNames
ldap.synchronization.personType=inetOrgPerson
ldap.synchronization.groupMemberAttributeName=member


but the above configuration fails with the below error:

15:46:40,220 Userystem ERROR [security.sync.ChainingUserRegistrySynchronizer] Synchronization aborted due to error
org.alfresco.error.AlfrescoRuntimeException: 03040000 User and group import failed

Caused by: javax.naming.NameNotFoundException: [LDAP: error code 32 - 0000208D: NameErr: DSID-031001CD, problem 2001 (NO_OBJECT), data 0, best match of:
'DC=itech,DC=com'
]; remaining name 'ou=Groups,dc=itech,dc=com'


Desperately looking for help on this. Hoping to get a response.

Thanks in advance.

I too would like to know how to get LDAP synch to work- However I am using my CAS server for authentication… but I do wish to have my LDAP synching with Alfresco for the users

Can anyone let me know a solution to this? I have been searching around for quite some time for a working solution but still haven't been able to figure out one.

Thanks for the help.

Hi

I haven't been able to get this resolved yet. Your help on this will be great. As I have told, I have been able to successfully login to the application using my AD credentials. But unable to synchronize the user and group info from AD LDAP.

Let me know if you would need any more info.

Thanks

Hi,
I had the same problem before, LDAP connection was OK but i was unable to make full synchro
I resolved this by putting the following synchronization options in alfresco-globals.properties
synchronization.import.cron=15 * * * * ?
synchronization.synchronizeChangesOnly=false
synchronization.syncOnStartup=false


my experience is that these options are not taken into account when put in ldap-ad-authentification.properties.

ps: these options are for test purpose, to make full synchro every minute at 15 seconds, you certainly should tune it for your need

Tell me what do you think about this. Thanks.

Hi

I tried providing these settings on the alfresco.global properties file. But still i didn't work out for me. Can you share the ldap.synchronization settings that you had used with me?

Thanks

Hello,

I would change this :
ldap.synchronization.groupType=groupOfNames
by
ldap.synchronization.groupType=group

And
ldap.synchronization.timestampFormat=yyyyMMddHHmmss'Z'
by
ldap.synchronization.timestampFormat=yyyyMMddHHmmss'.0Z'

as mentionned here : http://wiki.alfresco.com/wiki/Alfresco_Authentication_Subsystems
