How to configure full synchronization instead of incremental?

AFAIK Alfresco CE at startup performs only incremental synchronization with LDAP-AD. When I installed Alfresco and configured synchronization with LDAP-AD was performed a full synchronization. All the fields that I declared was displayed in the user profile. Now, I decided to add a few more fields. For example, skype and companyfax.

But they are not displayed.

Part of the alfresco-global.properties (similarly, in /alfresco/extension/subsystems/Authentication/ldap/ldap1/ldap-ad-authentication.properties):

    ...

    ldap.synchronization.synchronizeChangesOnly=false

    #synchronization.syncWhenMissingPeopleLogIn=true

    #synchronization.autoCreatePeopleOnLogin=true
...

In the logs I see that the synchronization is not performed:

 ...

...

I changed LDAP queries to (removed whenChanged):

ldap.synchronization.groupQuery=(objectclass\=group)
ldap.synchronization.groupDifferentialQuery=(&(objectClass\=group))
ldap.synchronization.personQuery=(&(objectclass\=user)(userAccountControl\:1.2.840.113556.1.4.803\:\=512))
ldap.synchronization.personDifferentialQuery=(&(objectclass\=user))

Then restart Alfresco and each time it performs a full synchronization. It seems that now everything is OK. Or am I wrong?..
