Hello
I have some issues with replication between Master and Slave LDAP servers.
Preconditions data: I have a Master server with a huge LDAP data And also I have about 200 Slave servers around the world which have a data replica in their databases.
What happened: I have applied a bckup on Master server. (Actually data have not changed except entryCSN)
entryCSN has been deleted from backup previously, before apply, for actualise data in LDAP database.
As a result I had a situation when all Slave servers starts replication.
The first question is: how I can avoid full replication after apply backup on Master? I understand that entryCSN changed and LDAP should sync some objects. But can I use another way to actualize the data in LDAP database instead of entryCSN?
The second question is: after apply backup and restarts the Master server I had a problem with local LDAP because all Slave servers start connecting and start their replication. In this case LDAP on Master server not responding even on localhost via ldapsearch. May I change some parameters to increase concurrent connections? Because LDAP starts not responding if the quantity of simultaneous connected of Slave servers exceeds 10-15
Thank you in advance Best regards, Alex
