iNetOrgPerson doesn't exist?
by Luca Stancapiano
Hi all, I'm triing to create a user with openldap 2.4
dn: uid=rrrrrr,ou=users,dc=my-domain,dc=com
objectClass: iNetOrgPerson
uid: iiiiii
but it doesn't seem recognize the objectClass producing this error:
adding new entry "uid=rrrrrr,ou=users,dc=my-domain,dc=com"
ldap_add: Invalid syntax (21)
additional info: objectClass: value #0 invalid per syntax
Using other object classes is ok. What's the problem?

dynlist vs memberof performance issues
by Mark Cairney
Hi,
I've been out the LDAP loop for a bit but the recent discussion of the
memberof overlay on 2.5 piqued my curiosity. Having upgraded a Dev box,
removed the memberof elements from the database and replaced the
memberof overlay with dynlist the queries appear to work as expected but
are both a) slow and b) heavily CPU-intensive on the LDAP server.

I'm guessing that as the values are computed that this will be heavier
on the CPU but it seems a bit excessive? Has anyone else noticed any
similar performance issues?
This is a relatively low-specced DEV server (2 vCPUs, 4GB RAM) so I
guess this could be a factor but there's no io waiting on the server and
no swapping?
The database is on a par in size with our Production service ( about
400K user objects with 1 group object per user and then about 80K actual
groups of users)

upgrading openldap 2.4 to 2.5
by CHIROSSEL, Olivier
Hi
I have an architecture with 2 openldap masters in mirormode ( refreshAndPersist ).
and few consumers ( refreshAndPersist )
The provisionning api and consumer request masters via vip ( sorry server configuration ),
It's complex for me to upgrade all the openldap in the same operation.
Can i upgrade only the 2 masters in 2.5, and the consumers in a second time ?
The replication between master in 2.5 and consumers in 2.4 work's fine ?
Thank's in advance for your replies.
Regards

Two notes on slapppasswd (old version)
by Ulrich Windl
Hi!
When using an old version (from 2.4.41) of slapasswd, I noticed two things:
1) Using "-h SSHA", slappasswd was asking for passwords first, then telling me: "Password generation failed for scheme SSHA: scheme not recognized"
I think "SSHA" is unique enough to recognize; and if it's not, then complain before asking for passwords.
2) When I mistyped the option as "-h '{SSHA}>'", slappasswd did not complain and produce some output.
I think if it's picky on the first case, it should also be for the second case (assuming the output "{SSHA}oTEDKWKn0fimGo6J8de0I5qRixGWJxhJ" was correct overall)
Maybe check if these problems still exist in the current version.

Ulrich Windl

LMDB, virtual machines, and copying mdb files
by selama＠gmail.com
I am working on developing a new document-oriented (XML+JSON) database, using LMDB as an engine, and I have two questions.
1. So far, it have been working really smoothly for me. But my one customer so far for the DB is really concerned about running LMDB in a virtual environment such as Docker, when performing reads and writes. Especially when mounting volumes. Their concern is because of the following caveat:
"Do not use LMDB databases on remote filesystems, even between processes on the same host. This breaks flock() on some OSes, possibly memory map sync, and certainly sync between programs on different hosts"
I think it shouldn't be an issue with Docker, but I want to be certain.
2. We have one server that updates the database, and another server with a read-only copy of the same database. Our plan was to simply copy the mdb files from the update machine to the read only machine, but we noticed that if we copy the file immediately after writing, the copy may end up being corrupted. My solution was to suspend all writing and wait few minutes before writing, to make sure everything back from memory, and I'm also using the "sync" command (not sure if it does anything here). It seem to be working, but I wonder if there is a more robust way of doing that? And also, is it safe to overwrite to the read-only server while it performs read transactions to the current file (or maybe rename it and copy to a new file with the same name)?

Read speeds, bottleneck, correct understanding?
by Sam Dave
Hi,
If my program reads through an LMDB database apparently slow at first run, but suddenly runs much quicker at the second run (which does exactly the same thing), can't I already say with confidence that my choice of LMDB - in this case its builtin memory mapping functionality - is already paying off in terms of read speeds?
I mean, that alone (exact same thing runs much faster the second time) already PROVES that the bottleneck was reading from disk as opposed to memory, right? I'm looking for excuses for patting myself on the back for investing in LMDB.

Sam

cn=config TLS Configuration Problem
by Timothy Stonis
Hi,
I am trying to setup an OpenLDAP 2.6.3 server and I’d like to only use olc configuration (no slapd.conf file). So far things are going okay, but I’m having a problem with TLS configuration. I am able to enable TLS using a self-signed certificate without any problem, however, if I try to disable TLS using the following LDIF:
dn: cn=config
changetype: modify
delete: olcTLSCertificateFile
-
delete: olcTLSCertificateKeyFile
-
I get the following error:
modifying entry "cn=config"
ldap_modify: Server is unwilling to perform (53)
I enabled debugging and cannot seem to see the error. I have also tried reordering the entries, doing one at a time, disabling ldaps:// binding, etc but nothing seems to work. If I just remove the certificate and/or key files, then the server does not start. Is enabling TLS a one way street? Or, should I just use slapd.conf?
As a second question, I read in an article online that there is a way to store the TLS cert(s) and key in the LDAP database itself. However, I cannot find any info on that in the documentation. Can anyone shed some light on that?
Thank you in advance!

RE25 testing call (2.5.14)
by Quanah Gibson-Mount
This is the first testing call for OpenLDAP 2.5.14. Depending on the
results, this may be the only testing call.
Generally, get the code for RE25:
<https://git.openldap.org/openldap/openldap/-/archive/OPENLDAP_REL_ENG_2_5...>
Extract, configure, and build.
Execute the test suite (via make test) after it is built. Optionally, cd
tests && make its to run through the regression suite.
Thanks!

Attribute Cert. schema (RFC 5755)

Hi there
I am looking for an RFC 5755 (attribute certificates profile) schema file.
I thought it was in pmi.schema, but it appears that no, unless I am
missing sthing.
Before creating one from the RFC, I would like to be sure it does not
exist somewhere I couldn't find.
Thanks in adv.

SyncRepl fails object class 'organization' requires attribute 'o'
by Sander Smeenk
Hi,
I'm trying to set up SyncRepl between two servers. When the SyncRepl
client connects and tries to start it logs:
| Entry (dc=example,dc=nl): object class 'organization' requires attribute 'o'
| syncrepl_null_callback : error code 0x41
| syncrepl_entry: rid=000 be_add dc=example,dc=nl failed (65)
There is only one such entry in the db and it has an 'o' attribute:
| dn: dc=example,dc=nl
| objectClass: top
| objectClass: dcObject
| objectClass: organization
| dc: example
| o: example.nl
| structuralObjectClass: organization
| [ .. create, modify, entry uuids etc ..]
What could i be missing here?
Regards,
-Sander.
