java.lang.NullPointerException in LDAP&AD users sync after upgrade from Alfresco 4.2 to 5.0

Hi all,We are testing upgrade from 4.2 to 5.0 but got blocked due a problem with LDAP&AD users synchronization.After we migrated our working LDAP & AD configurations from 4.2 to 5.0 during synchronization we got this error for each user in LDAP and AD:WARN [org.alfresco.repo.security.sync.C

Hello,

I just looked at the source code and configuration of Alfresco One 5.0 (5.0.0.6) and everything seems to be in order. The NameChecker code exists, a NameChecker bean is defined and injected into the ChainingUserRegistrySynchronizer. The NullPointerException should not occur. Which Alfresco One version of 5.0 did you use?

Regards
Axel

Thank you for the quick response!

We tested against Alfresco One 5.0.0.5, Alfresco CE 5.0.a and Alfresco CE 5.0.c and we always got the same error.
We even tested commenting the problematic code and then the synchronization passed without any errors.

In my opinion the problem is caused by null NameChecked object. There is a public method setNameChecker() in ChainingUserRegistrySynchronizer but I didn't look for the code responsible for calling it.

Hello,

the nameChecker is set via declarative Spring bean configuration in the Synchronization subsystem - there is no code that directly calls it. By any chance, do you have an addon installed that may have modified the synchronizer configuration? Or did you keep an old customization file (in extension directory) from 4.2 around?

Yes, there is something strange going on that has not been described.

Axel,

Your assumption regarding modification of synchronizer bean configuration was absolutely right. It appeared that there is a customization in our project that we inherited from another company that worked at our customer before us.
Adding

<property name="nameChecker" ref="nameChecker" />‍

to that custom bean definition made the synchronization working.

Many thanks,
Stoyan
