SynchroniseCache failed synchronisation for directory - NullPointerException

[kevinbecker]

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.

Hi @kevinbecker, 

I see that you opened a Support Ticket and was able to resolve this issue.  Could you provide us with the steps you took so that we can share it with the rest of the Community?
