Force a ldap sync

[johnnytv]

Hello,
I'm experimenting several errors with my AD configuration. I've recovered a backup and when start Alfresco this sync with ldap and work fine, however when restart service log file show the error: Cache update failed.

I found that problem is related with the LDAP synchronization. Exist some way to force a sync?, I've reviewed several documents on Internet and can't execute a resync.

Some ideas?

PD. Sorry by my english.

Alfresco 4.2.d

You can restart the alfresco service and that will do a resync.

ESWBitto,
When I restart service, log show "Cache update faile" (see my post: https://forums.alfresco.com/forum/alfresco-website/cache-update-failed-11052013-1754) and not load more.

You can trigger sync manually by JMX mbean.

MBeans -> Alfresco -> Schedule -> MonitoredCronTrigger-> syncTrigger ->Operation Tab -> excuteNow()

How to connect alfresco through JMX Please check it - http://wiki.alfresco.com/wiki/JMX

Why do you think forcing a sync will help?

Hello mrogers,
Thanks for your response, the problem with my Alfresco is:

1. If I restart alfresco service in this moment, this shows the next error and it doesn't start:

2. If I restore my backup from 11-04-2013, this not work and show the same error that point 1.
3. I've restored my last usefull backup (11-03-2013), then I start Alfresco service and this Synchronize with AD. After that, I can login in my Alfresco and work whitout problems. If I restart Alfresco, the log file shows the same error in the point 1 "Cache update failed".

4. I tried with other method:
a. First, restore backup
b. Change the values of ldap.synchronization.groupSearchBase and ldap.synchronization.userSearchBase by ou\=people,ou\=department,dc\=mydomain,dc\=com. In the steps 1 and 2, this value points to root AD (dc\=mydomain,dc\=com))
c. Then, I start Alfresco, this load fine.
d. Then, I restart Alfresco and load fine.

I assume that the last synchronization (init at 11-04-2013) has damaged some data, for this reason the log shows "Cache update failed" (https://forums.alfresco.com/forum/alfresco-website/cache-update-failed-11052013-1754).
So, I need to modify the values for ldap.synchronization.groupSearchBase and ldap.synchronization.userSearchBase and force a AD synchronization in the next restart. It's possible?

Let me know if you need more detail.
