Virtual list view problem
by Venish Khant
Hi all
I am using cpan Net::LDAP module to access LDAP entries. I want to
search LDAP entries using Net::LDAP search method. When I do search, I
want some limited number of entries from search result, for
this(searching) process I am using Net::LDAP::Control::VLV module. But
I get error on VLV response control. Please, any one have idea about
this error.
*
Error:* Died at vlv.pl line 50,
This is my example. I changed the font style of line 50
#!/usr/bin/perl -w

OpenLdap mirrormode cluster with 2 slaves.
by Jan Hugo Prins
Hello,
I have the following setup that gives me some issues at the moment.
I have 2 servers running Fedora 10 with OpenLDAP 2.4.19 that are running
in Mirrormode.
The sync between those 2 servers works just fine.
Besides that we have 2 frontend servers that rely heavily on ldap for
mail delivery and mail transfers. To make this workable we thought about
creating a readonly replica on these servers and tell the sendmail to
use the local ldap as primary. When we had an old version on these
servers (I think 2.4.12) everything worked fine. We now upgraded all
servers to 2.4.19 and the configuration moved to slapd.d format, and now
it looks like those 2 servers don't see the updates on the mirrormode
backend anymore.
I have to following config's, this was from before the migration to slapd.d:
==================
master 1

============================================
When I empty the DIT on a slave and start it again it gets the full DIT
just fine and I checked this. But after that it is not updated anymore.
Does anyone see here some obvious things I'm missing in these slave or
master configs?
Thanks a lot,

OpenLDAP client configuration with CentOS 5.3
by Cool The Breezer
Hi All,
We have a dedicated LDAP server and I would like to configure OpenLDAP client in our linux boxes running on centOS 5.3.
I have installed openldap client and changed /etc/openldap/ldap.conf with folllowing info
BASE dc=my, dc=net
URI ldap://10.122.12.13
But when I try to run ldapsearch, I get following error
SASL/EXTERNAL authentication started
ldap_sasl_interactive_bind_s: Unknown authentication method (-6)
additional info: SASL(-4): no mechanism available:
The objective is anybody having ldap id can login to linux box. At present, I am manually creating individual ids which we want to integrate with LDAP authentication.
I would appreciate your help

Nssov Problem Since 2.4.19
by Chris Breneman
Hi,
For the last few days, I've been trying to get nssov to work. I've
mainly been working with OpenLDAP 2.4.21, but this issue is present in
all releases since and including 2.4.19. It works fine in 2.4.18.
Everything compiles fine as expected, and the module loads (it seems),
but when I try to add configuration for the module with ldapadd, I get
this error:
ldap_add: Other (e.g., implementation specific) error (80)
additional info: <olcOverlay> handler exited with 1
Using the same build instructions, configuration, and everything, 2.4.18
works without this error. Some more details are below.
I'd try to fix it myself, but I don't really know where to start. I'd
appreciate it if someone could point me in the right direction.
Thanks,
Chris Breneman

Please reply to the mailing list, not to me directly. No, I'm not saying
anything like that. Since yours is a fresh setup, then your error (or the
bug) must be somewhere else. I have no clue at the moment; replying to
the list might allow someone not as clueless to provide support.

Trouble with memberOf Overlay
by Bill Keirskie
I was looking through list archives and a few weeks ago, someone posted some configurations for the memberOf overlay. I modified the configurations slightly and it looks like everything is installed (with no errors) and working, but when run an ldapsearch, it does not return the memberOf. Below is the install and configuration method. Any guidance on what to change or error logs to look at?
Thx Bill

Read Waiters growing
by Peter Mogensen
Hi,
I see a strange thing in cn=Monitor. Suggestions needed.
I have a huge database, and performance is great as long as olcReadOnly
is TRUE.
But a soon as I enable writes, the number of Read Waiters are growing,
even though there's no or very few Write waiters.
# Read, Waiters, Monitor
dn: cn=Read,cn=Waiters,cn=Monitor
monitorCounter: 311
# Write, Waiters, Monitor
dn: cn=Write,cn=Waiters,cn=Monitor
monitorCounter: 0
# Current, Connections, Monitor
dn: cn=Current,cn=Connections,cn=Monitor
monitorCounter: 210
I have idletime=120 and connections do around 30 reads each before they
are retired, but not many writes. Like this:
# Connection 5389, Connections, Monitor
dn: cn=Connection 5389,cn=Connections,cn=Monitor
monitorConnectionNumber: 5389
monitorConnectionOpsReceived: 32
monitorConnectionOpsExecuting: 0
monitorConnectionOpsPending: 0
monitorConnectionOpsCompleted: 32
monitorConnectionGet: 32
monitorConnectionRead: 32
monitorConnectionWrite: 0
It's slapd 2.4.21, BDB 4.8.26 and back_bdb.
Any hint to what could cause that many read-waiters, but only while
writing is enabled and even though there's not that many writes?

overlay chain and TLS/SSL
by Ralf Zimmermann
Hi all,
I think I have a problem with the overlay chain and tls. We have one physical
master and two slaves in VMware Vsphere4. Our configuration runs normally fine,
but sometimes we can't modify entries like passwords to the master. Then we
must restart the slapd at the slaves. After restarting slapd all works fine.
Then slapd works fine the wholy day. We can change entries or set passwords on
the slaves. Next morning we must restart the slapd again, because we can't
modify entries from the slaves. But we can query the slapd and syncrepl works
fine. Only things over the overlay chains doesn't work. I have the problem not
only with Version 2.4.20. I tested more Versions and actually 2.4.21 from
pysically hardware.
If I can't set entries on the slave I don't see any tcp packets from the slave
to the master. DNS, time and so on looks fine and everything else is working.
And if we restart slapd everything is working. Does anybody know what is going
wrong and if there exits a workaround. I read some things abount /dev/random,
/dev/urandom and kernel 2.6 in VMware. Can this be the problem?
Here the overlay chain configuration.
<snip slapd.conf>
overlay chain
chain-uri "ldap://eisenherz.camelot.de/"
chain-idassert-bind bindmethod=simple
binddn="cn=ldapadmin,dc=camelot,dc=de"
credentials="xxxxxx"
mode="self"
chain-rebind-as-user TRUE
chain-return-error TRUE
chain-tls start
</snip slapd.conf>
Any help is appreciated.
Regards
Ralf Zimmermann

posixGroup and groupofNames
by Siddhartha Jain
Hi,
Running CentOS 5.4 with stock OpenLDAP distro 2.3.43. Both classes, posixgroup and groupofnames are structural causing conflicts if one wants to use both. And while RFC2307bis is deleted by IETF, RFC2307 doesn't seem to have the same traction (or, does it)? So, what's a good option? Simply switch posixgroup to AUX in /etc/openldap/schema/nis.schema?
Thanks,
Siddhartha
