SynchroniseCache failed synchronisation for directory - NullPointerException

Question

Hi,

After upgrading Confluence from 5.10.8 to 6.5.2, I'm facing issues with the LDAP directory synchronisation. Here are the errors I have in the logs:

I tried to flush some caches (Embedded Crowd Users, Embedded Crowd Directory), to change username and lower_username when I saw they were differents in the user_mapping table with no effective result.

Does anyone got this issue before ?

Thanks.
