Re: OpenLDAP: contextCSN check across mirrors
Thanks for the reply.
"Added slapd syncrepl contextCSN storing in subentry (ITS#6373)". In
this point what I can understand is that contextCSN will also get stored
in suffix entries as well as to sub entries as well. Please correct if
That's wrong. Read the manpage and/or the ITS for the actual behavior.
I have some doubts if you can please help in making it more clear:
1) Can the contextCSN entry differ at the sub entry level if compared
with suffix(root) entry level?
It will only be in one place or the other, not both.
2) If this is the case then a check will be required to each and every
entry if the sync is there at the dn level across mirrors and scripts
need to be modified so as to put a loop till all the entries has been
checked in that particular LDAP tree. Please correct if wrong.
3) how will the contextCSN entries will get changed. Does checkpoint
plays a role in changing the contextCSN value or not?
4) provider will not change the contextCSN until the whole data get
but will consumer will still be able to do so. Is this still the
scenario in the new version?
I don't understand the question.
Many Thanks in advance!!
