The accesslog should never write an operation that can't be replicated. If
the MOD is a valid LDAP operation (which I think it is), then it should be
accepted at the frontend. The issue may be more in delta-syncrepl's
handling of the write op than anything else.

RHEL may have compiled liblmdb in statically. That's the default
configuration for OpenLDAP.

It is generally advised to not use the builds provided by RedHat, including
their lack of LMDB support. Other options include the LTB project
(<https://ltb-project.org/download#openldap>) which include LMDB support
along with BDB and require no support contract. Alternatively, the company
I work for (Symas) provides builds of OpenLDAP backed by LMDB, but ones
that allow for replication require a support contract.

This is ITS#8336, fixed in OpenLDAP 2.4.44/LDMB 0.9.18.
I suggest you upgrade to the current OpenLDAP Release (2.4.45/LMDB 0.9.21)

Exponential increase in Free Pages
by John Holder
Hi OpenLdap list
I have a question on how to interprite the Free Pages stat from mdb_copy. I
may be reading this particular stat wrong.
After using the compact utility from mdb_copy -c, free page count will
start at zero and immediately increase to where it left off before the
compact then increases by a few.
I was just wondering if the free pages count is actually a free pages
pointer where it left off instead of a count of total free pages.
Is it possible that the sparse file needs holes dug in using fallocate -d
or something else.
Thank you!

Partial OpenLDAP replication
by Paulo Coimbra
Hi everybody,
I need to replicate part of our OpenLDAP Directory (Main) to other
openLDAP servers (Customers), like this:
MAIN...................................CUSTOMER
OU=People,dc=XXX ---> OU=XXX_Users,dc=XXX
**OR**
Customer's LDAP query at Main (if a user is not found on Customer LDAP
database) without any kind of replication (I really prefer this).
How can I do this? Any Sugestion?

Re: publisher migration or upgrade
by Scott Bickford
Quaanh,
I did not use -q on slapadd.
Essentially I do a slapadd -f /etc/openldap/slapd.conf -b o=myco,c=us, -v
-w > load_myco.log
We have three databases, so there are three slapadd above with -b
o=myapps,c=us -v -w > load_apps.log and a -b o=mycust,c=us -v -w >
load_cust.log
We have a very large custom schema and three databases, so we are still
using slapd.conf instead of cn=config. The schema dates back to the 1990s.
The database is "bdb" on all three schemas.
The three production subscribers are load balanced and just one publisher,
which is not load balanced. It is used by some java applications (which
are also clustered) for updates. I am hoping that we can replace
subscribers over the course of several weeks since there is quite a bit
involved and have them up and running in production with the publisher
still on 2.4.40 and the subscribers on 2.4.44.
I am working with a VMWare person on planning how we are going to rename
the servers.
