I don't know. There is no winsync information in the access log. Note
that the access log records client accesses to the directory server, and
in winsync, the directory server itself acts as a client to AD, so
winsync will log nothing in the access log. The errors log could be
helpful, and especially using the replication log level (which is also
used for winsync logging). The Windows Event Viewer is useless for
winsync issues.

Performance tuning - where to begin?
by Daniel Fenert
Hi,
I have performance problem on 389-ds server and don't really know where
to start fine tuning.
My current setup is master (2xQuadCore, 8GB RAM), few read-only slaves.
It works (more or less) without problems, but I would like to migrate to
multi master (2 master servers).
To check if one master will handle the whole load, I've tried switching
clients from slaves to master one by one.
After switching clients from third slave, I've encountered weird problem
- master was about 50% busy (looking at the cpu, no IO waits), but there
was problem with new connections.
Looking at the network level - there was SYN from client, but no ACK
until one or two retransmissions of SYN.
I've tried increasing thread number (from 30 to 60), but problem still
exists.
The problem is near 400-500 connections/second. My whole load is
~750conn/sec. Looking at the CPU usage, this server should handle the load.
It works stable with load ~300conn/sec.
There are plenty of configuration options, where should I look first?

1.2.8 Windows sync agreement initialization
by Juan Carlos Camargo
Hi,
I'm running 389-ds version 1.2.8 on CentOS 5x and configured a windows
sync agreement against a 2003 active directory server. Everything works
as expected. However, everytime I restart the directory server (service
dirsrv restart) I need to reinitialize the windows agreement. Messages
such as "Replica has no update vector. It has never been initialized"
continously filling the error log until I proceed with the init. But
the replica was initialized and conversations between 389 and AD were
working nicely. And what I would not want at all is to lose any changes
made on either side as a result of the initialization process. My
question then, is this the normal behaviour ?
Thanks!

Giving up 389ds
by Juan Carlos Camargo
I must say, I'm giving up the product. It seems that I'm unable to setup
a successful windows sync agreement to our active directory server. I
got tired of trying, googling, checking the list, posting, getting wrong
answers and so and so.
Good luck!

FYI and OT: PAM Weirdness
by Gerrard Geldenhuis
Hi
I have seen an interesting problem which I thought would be useful for anyone on the list to know. I ran into it ones to many so sharing my solutions to spare others the suffering. :D
If you have certificates in /etc/pki/tls/certs on a CentOS 5.5 box and one of the certificates has root:root 600 permissions it will break LDAP login if you use certificates.
What happens is that as the client libs try to find the correct certificate it cycles through all of the certificates (as shown by strace) finds the correct certificates but also find an unreadable certificate and then refuses to connect to the LDAP server for some tasks. You can login but you will see something like the following:
Last login: Wed Feb 9 09:56:32 2011 from 10.5.11.44
id: cannot find name for user ID xxxx
id: cannot find name for group ID xxxx
id: cannot find name for user ID xxxx
[I have no name!@testbox ~]$
You will also see the following in /var/log/messages
Feb 9 09:53:01 testserver nscd: nss_ldap: reconnecting to LDAP server (sleeping 1 seconds)...
Feb 9 09:53:02 testserver nscd: nss_ldap: could not search LDAP server - Server is unavailable
Arguably the file permissions should never be 600, but also arguable the PAM and or other libs should not be so sensitive to fail on only one file being wrong.

Hi,
I have a working MM setup and I exported my db with db2ldif.pl with the -r option:
db2ldif.pl -D 'cn=Directory Manager' -w password -n userRoot -r -a /tmp/db_replica.ldif
The errors file do not indicate an issue:

and the ldif file itself looks fine to me as well.
Then, I tried to import the ldif file with
ldif2db.pl -D 'cn=Directory Manager' -w password -n userRoot -i /tmp/db_replica.ldif
This fails with the following errors log:

389 DS is reseting connections
by Diego Woitasen
Hi,
I have 389 DS 1.2.7.5 running on Debian Squeeze. It was working fine
but the last days the process started to hang very often. I restart
the service, works fine for a few minutes and hangs again. The process
is running, accept connections but reset them.
The only error message that I see is from ldapsearch:
ldap_start_tls: Can't contact LDAP server (-1)
ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)
I ran ldapsearch with strace, the last lines:
socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3

setsockopt(3, SOL_SOCKET, SO_KEEPALIVE, [1], 4) = 0

I tried to trace ns-slapd, but I don't see anything special (except
the ENOTCONN error in getpeername() but it's on a different FD):

Any hint to help to find the problem? I tried with different slapd log
levels but i don't see anything special. I don't except a magical
solution, only a hint to discover what's happening.

Admin Server not showing Indexes
by Techie
Hi All,
I am using CentOS-DS running on CentOS 5.5 Final. Package versions are below.
I am having an issue where when I create indexes either with
db2index.pl or with an ldap add operation using the cn=index task, my
indexes do not show up in the graphical admin server tool. i get no
errors and the error log says the indexes finish fine. The indexes
also show up under /var/lib/dirsrv/slapd-instance/dbname with a .db4
extension. Has anyone seen this behaviour?
Thank you
