Re: openldap 2.4.23 hangs
by Robert W. Smith
Thanks for the response. It'll take me a couple of days to work this in my schedule. Just so that you know the new auth servers (ldap & samba) will be 64-bit and this is what I will compile to.
Unfortunately we may never get to the 2.5 release.

Re: Overlay Chain Extended Passmod Problem

sorry for my uncleary description. The OpenLDAP Master is at time a
self-compiled OpenLDAP 2.4.20 on a Sles11. The Slaves have different packages
and are different distros. We use Ubuntu, Suse and Debian installations. The
effect is always the same. In the morning the first extended passmod operation
fails. We can't see a tcp packet on the outgoing interface on the slave. After
the first fail all works fine. The whole day. There are working more than 500
User on the Samba Servers without problems. If we restart the slapd before the
first extended passmod the operation is successfully. We have checked ntp, dns,
routing, firewalls and so on without a result.
We define and undefine idletimeouts, TLSRandFile and so on. But without a
result. In the morning before the User are working the first extended passmod
over overlay chain and TLS fails. If we disable TLS always works fine.
I would like to know where the problem is. At the first time we searched at the
virtual systems but the problem exists also on physical machines.
Here our configure command:
---------------------------
./configure --with-tls --with-cyrus-sasl --enable-overlays --enable-modules \
--enable-rewrite --enable-wrapper --enable-dynamic --enable-ldap
We use openssl support.

Sorry. I had not configured the pam_ldap (/etc/ldap.conf) config file
properly. The certifikate entries were missing.

saslauthd permission denied
by Joshua Schaeffer
I'm having a difficult time setting up pass-through authentication. I've set it up before but can't seem to get it to work this time. I've done the following:
- Created the slapd.conf for SASL.
- Started and ensured saslauthd is running.
- Added the openldap user to the sasl group.
- Verified with testsaslauthd that SASL is working
- Restarted slapd and the server just to make sure all settings/permissions are updated properly
However I always get a permission denied error message when slapd tries to contact saslauthd:
Feb 5 12:13:56 bllldap01 slapd[477]: SASL [conn=2866] Failure: cannot connect to saslauthd server: Permission denied
I've even temporarily enabled the shell on the openldap user and tested testsaslauthd which returned a successful result. I feel like I'm missing something obvious and maybe a fresh set of eyes can point that out. Below is all the relevant details of my system:

Re: openldap 2.4.23 hangs
by rwsmith＠bislink.net
Hi,
I just wanted to report back on this issue.
I downloaded the source RPMS from abennet's blog found at:
http://wordpress.clarku.edu/abennett/
While this was only version openldap-2.4.30 this seemed to me a more expedient
approach as I would have to update about a dozen machines. I was able to
successfully compile and rebuild the SRPM on my CentOS 6.3 64-bit platform and
replace the core Openldap software and DB software.
While the updated software has only been running for three days in a 4-way
multi-master sync replication configuration, it has run without the epoll: busy
problems that were hanging slapd (2.4.23) at least once a day. It also seems to
have resolved a few lingering replication issues that I was experiencing with
the CentOS core Openldap software.
There are a few quirks with installing this software (didn't like self-signed
certs for one) but no show stoppers for me.
It would be nice if Rehat or CentOS could get the fix mentioned below into their
core Openldap.
Thanks for your help.
Bob

RE: OPENLDAP SYNCREPL
by Borresen, John - 0442 - MITLL
Maybe it's just that it is near the end of the day...but, first here is my
ldif to add the provider to my cn=accesslog:
dn: olcDatabase={2}bdb,cn=config (I've tried it with {1}, {2} and nothing)
changetype: add
objectClass: olcOverlayConfig
objectClass: olcSynProvConfig
olcOverlay: syncprov
olcSpNoPresent: TRUE
olcSpReloadHint: TRUE
Receiving the following error:
ldap_add: Invalid syntax (21)
additional info: objectClass: value #1 invalid per syntax

Looking at my old ldif's for creating this in the first place (this my
original LDIF to create the cn=accesslog):

Originally, I had the olcOverlay, etc in this but it failed out with the
same error as above; so, I took it out in the hope of inserting it later
obviously with no luck.

Quanah's followup was correct: you have the consumer configured for
delta-syncrepl but you're missing the provider on your cn=accesslog
database.
See the Admin Guide section 18.3.2.

ldapbin : Invalid DN Syntax (34)
by Joseph vasanth
Hi,
I am a newbie on openldap. I have just installed openldap on FC11. I am facing issues when i try to bind. When i do an ldapsearch it throws the ldapbin : Invalid DN Syntax (34) error.
I have the following information
slapd.conf

# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.

#Require integrity protection (prevent hijacking)
#Require 112-bit (3DES or better) encryption for updates
#Require 63-bit encryption for simple bind

# Sample access control policy:
#Root DSE: allow anyone to read it
#Subschema (sub)entry DSE: allow anyone to read it
#Other DSEs:
#Allow self write access
#Allow authenticated users read access
#Allow anonymous users to authenticate
#Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
#by self write
#by users read
#by anonymous auth
#
# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
# updates to rootdn. (e.g., "access to * by * read")
#
# rootdn can always read and write EVERYTHING!

Enter LDAP Password:

additional info: invalid DN
I have installed and the installation went fine. but ldapsearch keeps giving the same error
i also tried other combinations on the dn like adding a ou=Peopledc=primecorp,dc=com, many other combinations but i stll kept hitting the same error or "invalid credentials".
I completley stuck as to whether i am putting the correct information.I am not able to see what is exactly wrong with the config.
I am using Fedora Core 11 by the way.
If someone could please help me with this i would be so appreciative, LDAP looks so easy to set up yet there is something probably so small preventing it being set up correctly. if you need any more information on this just ask me.

Re: CSN too old, ignoring - and therefore not syncing
by Gavin Henry
Try dropping nopresent and reloadhint relating to ITS5669. You only
need these two syncprov settings on an accesslog db.

Re: CSN too old, ignoring - and therefore not syncing
by Gavin Henry
Also, interval is only used in refreshOnly mode and overlays should be
listed last before the next database definition stacked the order you
want them loaded (in your case leave as is as they are in the correct
order).
Thanks.

You should submit an ITS for this. This PcacheAttrset directive is not

failing to match your search request.
