ppolicy and simpleSecurityObject exemptions
by Nick Urbanik
Dear Folks,
What is the best/right way to exempt system users (entries that have the
simpleSecurityObject objectclass) from the ppolicy default policy?
Is it to create another policy without restrictions and specify that
each system user should use that policy using pwdPolicySubentry?

search ldap
by Noel Akins
I have a dumb question. I've been struggling with LDAP for a couple of weeks
now, working on it at home at night. I seem to have something working here
given the ldapsearch i tried doing below. I had started with a base.ldif and
added a user via a add_user.ldif. I assume the numEntries: 1 is the user that I
entered. But for the life of me, I can't seem to figure out how to view that
entry. What do I need to do actually see the entry?
Thank you.
ldapsearch -L -x -b 'dc=mergeemerge,dc=org'
version: 1
#
# LDAPv3
# base <dc=mergeemerge,dc=org> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#
# mergeemerge.org
dn: dc=mergeemerge,dc=org
objectClass: dcObject
objectClass: organization
o: mergeemerge
dc: mergeemerge
# search result

Strange log entries
by Peter Schütt
Hallo,
I got the following log entries in /var/log/messages
Apr 5 13:19:51 myhost slaptest: auxpropfunc error invalid parameter supplied
Apr 5 13:19:51 myhost slapd[18435]: auxpropfunc error invalid parameter supplied
This is funny because I redirect the logs of OpenLDAP in an own file
by an entry in
/etc/rsyslog.conf:
# OpenLDAP
local4.* /var/log/ldap.log
What does these log entries mean?
Ciao

Speeding up BDB question
by Cannady, Mike
I have a situation where I need to delete a major branch of my DIT and
reload it with a new ldif file on live systems. My current
configuration is a two node multi-master running on Red Hat Enterprise
5.4 with openldap 2.22 and BDB 4.8.26.
With both masters running, when I delete the branch it takes about 1.5
hours and the reload (ldapadd) takes about 6-7 hours. I've researched
the documentation on Berkeley but didn't make any headway to reduce the
time. It appeared to me that BDB was doing syncs (lots and lots of disk
writes). To test this, I moved the database directory of both masters
to a ram drive (mount ramfs) that could hold the whole database
directory with room to spare and changed the configuration to use the
new location.
I reran the tests and the results were that the delete took 6 minutes
and the load took about 13 minutes. This is definitely a lot faster and
the other master kept up with the updating master.
So my question is there anyway to configure Berkeley to come close to
this? Is there someway to disable the syncs?

Hi,
If it was the same problem that I had some time ago, it was due to idle
connections that I gold slapd to close after x seconds.
Check yours, and eventually set a keep alive parameter on your client,
nss_ldap.

got those lines. Who can explain to me?

beginner -old slapd.conf
by eric
I was familiar configuring openldap with slapd.conf ver 2.3 I recently
install 2.4 and am having a bear of a time trying to follow any
instructions from any source... man pages, openldap.org, and
https://help.ubuntu.com/10.04/serverguide/C/samba-ldap.html
This part is nerve racking on the ubuntu site... after I generate part
3, part 4 says...
##########################
4. Edit the generated /tmp/cn\=samba.ldif file, changing the following
attributes:
dn: cn=samba,cn=schema,cn=config
...
cn: samba
##########################
but it does not say what I should change the attributes too... just
gives an example that is (in my opinion poor) for a beginner like my self.
Following instructions and learning seemed so much easier with 2.3
Can someone please let me in to the 2.4 LDAP world?
I just want to get something in 2.4 setup to play with so I can learn
setups with 2.4
Thanks for any help in advance.

Tuning openldap, nss_ldap and pam_ldap

Hello openldap users!
I've got Openldap 2.4.23 that used as authentication and authorization
server for about 40-50 servers.
OS - FreeBSD 8.1.
It's not heavy loaded.

But on my servers sometimes I see in logs something like
on FTP-server:
Mar 25 21:55:32 someftp ftpd: nss_ldap: could not search LDAP server -
Server is unavailable
Authentication works fine, no problems. But want to find out what can be
wrong.
To understand this problem I installed ldap-stats utility and made it run:
/var/log/debug.log - it's half day openldap server usage log.
