How can the Synchronisation in LDAP authentication in conflunce 4 be stopped?

Hi,

I have installed Confluence 4 on Linux system and have configured confluence to use LDAP authentication. While logging into confluence, the synchronisation process starts and it throws timelimit exceeded or sizelimit exceed exceptios. I changed LDAP filters accordingly and set synchronise interval to 1 hour. Nothing works out to make the login successful. Everytime I login to confluence, the synchronisation starts.Can anyone tell me how to stop the synchronisation process or any other solutions to fix this issue?

Exception details are given below.

Hi Suguna,
I believe you will find the answer at the following knowledge base article.

LDAP Sync Fails due to LDAP Error Code 3 - Timelimit Exceeded

Basically, we increase the timeout to accomidate the time taken to retrieve results. Alternativly, we could estblish the direcotry to be a delegated direcotry. What this would mean is that the direcotry no longer synchs and retrieves the users information upon login. To do so, create a new user direcotry and select 'delegatd' and enter the info as you normally would.

Cheers,
Andrew

Another option to avoid synchronization problemas between Confluence and LDAP is to use Delegated instead of Connector. Basically Delegated will import the LDAP user in its first login, while connector synchronizes: https://confluence.atlassian.com/display/DOC/Connecting+to+an+Internal+Directory+with+LDAP+Authentication
