I have a question.

I am going to check ldap replication with nagios. I have found a script for this.
The main goal is to check contextCSN on master and slave servers. Then it compares both.

To check this I tried to do it myself with the command ldapsearch.
On master:
ldapsearch -h ip_address -x -b "dc=my_domain,dc=com" '(contextCSN=*)' contextCSN
The result was like this:
contextCSN: 20110120102349.633165Z#000000#000#000000
But on slave server I didn`t get anything

Help me please. I will be very grateful to you
