LMDB data growth - overflow pages
by Christian Sell
Hello,
I am trying to use LMDB to store large (huge) amounts of binary data which, for
the reason of limiting memory footprint, are split into chunks. Each chunk ist
stored under a separate key, made up of [collectionId, chunkId], so that I can
later iterate the chunks using a LMDB cursor. Chunk size is configurable.
During my tests, I encountered a strange scenario where, after inserting some
2000 chunks consisting of 512KB each, the database size had grown to a value
that was roughly 135 times the calculated size of the data. I ran stat over the
db and saw that there were > 12000 overflow pages vs. approx. 2000 data pages.
When I reduced the chunk size to 4060 bytes, the number of overflow pages went
down to 1000, and the database size went down to the expected number (I
experimented with different sizes, this was the best result). I did not find any
documentation that would explain this behavior, or how to deal with it. Of
course it makes me worry about database bloat and the consequences. Can anyone
shed light on this?
thanks,
Christian

Human-friendly olcAccess management
by Bogdan Rudas
Hello all,
I would like to start use of olcAccess rules, are there human-friendly
editor for that ACLs?
I can't even use line breaks in ldif file to make my restrictions a bit
more readable! I strongly dislike very long string values, one day this
will cause mistake and access violation.
I've tried with Apache DS, ldif import and few puppet modules, everything
require huge line ACL.
Any help will be welcome.

Tuning number of entries sent during syncrepl?
by Bannister, Mark
It takes about 10 minutes to synchronise about 300,000 entries across the WAN, but the WAN isn't that slow here, I can transfer an LDIF file much faster than that over NFS.
Before LDAPCon last week, I had been working on a solution to this problem, where I would get the master server to dump its contents once a day to NFS, and then replicas could build initially from that. It was taking quite a bit of work, and it was slightly annoying that I needed to jump through these hoops.
Last week I was speaking with someone at LDAPCon who told me he had come across the same problem, and it turned out to be something to do with the maximum number of entries that can be transferred in one go? - although I may have misheard this, so please forgive me if details are not entirely accurate. But apparently this is tunable, and if I increase it, my 300,000 entries will replicate much much faster.
Any ideas? Sorry I'm a bit sketchy on details.
Thanks,
Mark.

Problem making refint_nothing working
by katgb
Hi all,
I tried for some days to make refint overlay work with refint_nothing
filled.
The slapo-refint man page says :
refint_nothing <string>
Specify an arbitrary value to be used as a placeholder
when the last value would otherwise be deleted from an attribute. This
can be useful in cases where the schema requires the existence of an
attribute for which
referential integrity is enforced. The attempted deletion
of a required attribute will otherwise result in an Object Class
Violation, causing the request to fail. The string must be a valid DN.
but each time I try to delete the last member from a groupOfNames group,
the deletion is refused because of schema violation. That's ok without
refint_nothing but with the string set it should replace last member,
right ?
I tried to increase loglevel to 16383 but can't see any debug for refint
overlay. So I'm not sure if refint is working or not. Is there another
way to have some debug information from refint ?
I have included my configuration, ldap tree and log content below. For
the logs, I have snipped the content to the error directly but can
provide full log if required.
The tests are running on debian jessie 8.2 and slapd version
2.4.40+dfsg-1.
And I know I can place the placeholder manually but doing it by hand
each time is not what I want and, more important, I want to understand
why the module is not worrking like it should.
I hope I have posted to the right list and if there is something missing
please ask.
Thanks for help.

Trying to set up multimaster syncrepl, error attribute 'olcTLSCertificateFile' not allowed , why?
by Betsy Schwartz
I inherited a pair of (interestingly configured) ldap servers from a
previous owner and I'm trying to get them to replicate to each other
(actually, starting with two new VM copies, with the goal of ending up with
four masters spread over two data centers). The VM's are running RHEL6 and
openldap 2.4.40.
When I try to add replication using the ldif included at the bottom of
this post , I get this error and then cannot restart slapd
--
[root@ldap01 tmp]# ldapmodify -Y EXTERNAL -H ldapi:/// -f /tmp/repl.ldif

modifying entry "olcDatabase={2}bdb,cn=config"
ldap_modify: Object class violation (65)
additional info: attribute 'olcTLSCertificateFile' not allowed
--
slapd restart error in the log is
read_config: no serverID / URL match found. Check slapd -h arguments.
(I assume this is coming from my three new syncprov providers which have
nothing to provide?)
The only reference I found to TLS anywhere was here
[root@ldap01 tmp]# slapcat -s olcDatabase=\{2}bdb,cn=config |grep TLS
olcTLSCertificateFile: /etc/pki/tls/certs/foobar_cert.pem
olcTLSCertificateKeyFile: /etc/pki/tls/certs/foobar_key.pem
Those files do not exist, never have!
(I admit I tried, and failed, to delete the reference)
What can I do to fix the TLS error? Where is there a TLS dependency in this
picture? Thank you for any clues!

replicating cn=config generates LDAP_NOT_ALLOWED_ON_RDN
by Chris Cook
Openldap 2.4.31
I create my read-only ldap hosts with a stub config that contains a syncrepl statement:
olcSyncrepl: {0}rid=001 provider=ldaps://ldap.savagebeast.com binddn="cn=
admin,cn=config,cn=slave" bindmethod=simple credentials=$PW searchbase="cn=
config,cn=slave" type=refreshAndPersist retry="60 +" timeout=3 suffixmassage=
"cn=config" schemachecking=off
That on first run with a –c ‘rid=001’ flag syncs the rest of the configs and associated databases from the primary servers. Leaving the config database as:
# AUTO-GENERATED FILE - DO NOT EDIT!! Use ldapmodify.
# CRC32 3c65cc7d
dn: olcDatabase={0}config
objectClass: olcDatabaseConfig
olcDatabase: {0}config
olcRootDN: cn=admin,cn=config
olcUpdateRef: ldaps://ldap.savagebeast.com
structuralObjectClass: olcDatabaseConfig
entryUUID: fee78e38-2723-1030-8342-0d5a80dcc32a
creatorsName: cn=admin,cn=config
createTimestamp: 20110609203711Z
olcRootPW:: x==
olcSyncrepl: {0}rid=001 provider=ldaps://guess-who.savagebeast.com binddn="cn=
admin,cn=config,cn=slave" bindmethod=simple credentials=x searchbase
="cn=config,cn=slave" schemachecking=off type=refreshAndPersist retry="60 +"
timeout=3 suffixmassage="cn=config"
entryCSN: 20151119013205.450738Z#000000#000#000000
modifiersName: cn=admin,dc=savagebeast,dc=com
modifyTimestamp: 20151119013205Z
This works great for the first run, but subsequent changes to the cn=config,cn=slave entries on the primary servers generate a replication error on the downstream hosts.
564fc719 syncrepl_entry: rid=001 be_search (0)
564fc719 syncrepl_entry: rid=001 olcDatabase={2}hdb,cn=config
564fc719 <= acl_access_allowed: granted to database root
564fc719 send_ldap_result: conn=-1 op=0 p=3
564fc719 send_ldap_result: err=67 matched="" text="Use modrdn to change the entry name"
564fc719 null_callback : error code 0x43
564fc719 syncrepl_entry: rid=001 be_modify olcDatabase={2}hdb,cn=config (67)
564fc719 syncrepl_entry: rid=001 be_modify failed (67)
Which is LDAP_NOT_ALLOWED_ON_RDN.
The only change to be synced was the addition of an olcDbIndex to one of the databases.
The suffix massage seems to still be in place:
564fc719 syncrepl_message_to_entry: rid=001 DN: olcDatabase={2}hdb,cn=config,cn=slave, UUID: ef2a6d04-b2cf-1033-9ca0-37a633abeda5
564fc719 ==> rewrite_context_apply [depth=1] string='olcDatabase={2}hdb,cn=config,cn=slave'
564fc719 ==> rewrite_rule_apply rule='(.*)cn=config,cn=slave$' string='olcDatabase={2}hdb,cn=config,cn=slave' [1 pass(es)]
564fc719 ==> rewrite_context_apply [depth=1] res={0,'olcDatabase={2}hdb,cn=config'}
564fc719 >>> dnPrettyNormal: <olcDatabase={2}hdb,cn=config>
Any pointers on how to troubleshoot why this error is called?

Building for windows. Again.
by Kristoffer Sjögren
Hi
I'm trying to build LMDB with Java/JNI bindings with Visual C++
Project Builder 9.00.30729 (vcbuild).
Unfortunately, vcbuild don't ship with inttypes.h, stdint.h, or a sane
ssize_t. So I searched around and found a few candidates [1] of
inttypes.h and stdint.h that seems to be working for py-lmdb.
However, unistd.h seems broken for windows - and the python guys use
python.h instead.
Any ideas where I might find a good unistd.h?
Cheers,
-Kristoffer

multi-value attribute virtual view of single attribute
by Jason Whitener
If I had a multi-valued attribute like
cn: var0:value
cn: var2:value
cn: var3:value
is there a way to expose each varX as if it were an attribute for search
filter purposes?
For instance, ldapsearch.....&((objectclass=person)(var0=value))
I started looking into slapo-rwm. Is that the best way to accomplish this?

ERR_employeeadd {'info': 'modifications require authentication', 'desc': 'Strong(er) authentication required'}
by Andrei Valoshyn
Hello!
I have slapd 2.4.39 and python 2.6
I tried to create an user via python when I tried do that with root
permission - it's OK. But when I did this with config in slapd.conf
"access to * by
group.exact="cn=LDAP_admins,ou=Roles,ou=Groups,dc=exadel,dc=com" write"
I have an error " ERR_employeeadd {'info': 'modifications require
authentication', 'desc': 'Strong(er) authentication required'} "
I tried to use " l.protocol_version = ldap.VERSION{2,3} " via 389 port
My function for adding ldif is :
l = ldap.initialize(server)
l.simple_bind(username, ldapsrvpassword)
def employeeadd():
ldif = modlist.addModlist(attrs)
l.add_s(dn,ldif)
Will be very appreciate for any help

sasl-auxprop (and sasl/slapd.conf)
by Simone Piccardi
I'm trying to understand which values I can use for the sasl-auxprop
directives and how to configure (if possible) sasl/slapd.conf.
I was trying to use the users created with slappasswd2 -c (as written in
the Administration guide) but no sasldb file was open by the server (I
straced out a full session). I tried to put an explicit configuration in
sasl/slapd.conf, and stracing the server I saw it was open and read, but
the configuration inside is just ignored.
Reading the manpage I found it says that sasl-auxprops "Specify which
auxprop plugins to use for authentication lookups." and that the default
is use the slapd internal support.
But I did not define this one, and sasl/slapd.conf still seems to be
ignored. And no possible values for the available plugins to use as
sasl-auxprops parameter are listed.
I could get DIGEST-MD5 authentication working putting the password
inside the server (userPassword in CLEARTEXT), so it seems that the
default is used anyway. But I'd like to have it working using using
sasldb or configuring sasl/slapd.conf to use saslauthd.
Regards
Simone
