LDAP sync error : Last encoded character..

Hello ! 

I have a critical error for one of our managed platforms with some LDAP users synchronized to Alfresco.

Here is the callstack :

I found nothing about this issue except this topic : https://hub.alfresco.com/t5/alfresco-content-services-forum/it-s-impossible-to-show-users-list/td-p/... but it don't seems to be related.

What we tried is : 

  • Search for related issues
  • Delete / recreate the LDAP entry manually (to check that there is no blank space in the fields or sth)
  • Set Alfresco in full sync mode and restart

Do you know anything about this issue ? This is blocking the LDAP synchronization of a French university for a few days now..

We are currently running in Alfresco 6.2 and we know it will be deprecated the next month, update is planned but can't be done as fast as we want in production environments, we are more looking for a fast fix here

Thank you a lot for your help !

Re: LDAP sync error : Last encoded character..

Hi:

Try to put DEBUG mode for ldap for getting more info about the problems of the sync (with the help of Alfresco Support Tools) or custom-log4j.properties

log4j.logger.org.alfresco.repo.security.sync=debug

But probably, you will need to change / fix an ldap user in OpenLDAP/AD (which is not an Alfresco part).

Regards.
