OpenLDAP 2.2 was moved to Historical status a few years ago. Upgrade to a
current supported release if you want anyone to look into this.

Thanks for the report, too bad you didn't forward it to us sooner.
This is now fixed in CVS HEAD.

Hi,
ldapsearch gets stuck retrieving info and after some minutes the following error
message is thrown:
ldap_result: Can't contact LDAP server (-1)
I'm using:
ldapsearch -V
ldapsearch: @(#) $OpenLDAP: ldapsearch 2.2.13 (May 3 2007 03:01:11) $

Things used to work until one day when it began to give problems, so it could be
a site network port filtering problem, but our network administrator does not
know how to debug, so we would need any hint on how to trace back the problem.
The command, which starts working but after some time gets stuck, is:
ldapsearch -p 2170 -h exp-bdii.cern.ch -x -LLL -b "o=grid" -d -1
Of course, we CAN do a telnet on that port and that host. Any help is really

(ITS#5503) Openldap segmentation fault when running syncrepl.

Full_Name: Chuck Short
Version: 2.4.9
OS: Linux
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (99.224.150.216)
When running the following scripts openldap crashes when trying to run a
syncrepl from a slave server. The original bug report can be found at:
http://bugs.launchpad.net/bugs/227178.
Steps to reproduce it:
1. Download the attachment in the bug report.
2. mkdir /home/amg1127/
3. Unpack the attachment in the just created directory.
4. Run the ./create-master-base.sh script.
5. In one terminal run the run-master-slapd.sh script.
6. In another terminal create the run-slave-slapd.sh script.
7. The result will be a segmentation fault in the slave server.
Thanks

That's why I said "treated as" X-ORDERED (when occurring in cn=config).
If that's too cumbersome though:

An attribute private to OpenLDAP should have a prefix like "olc",
but an RFCed attribute must wait till (X-)ORDERED is standardized.
I suggest "olc-note", then. Still stands out from the rest since the
others do not use hyphens, and also sorts it before the other "olc"s.

Since yesterday, we are facing LDAP problems while insertion of data. When we
try to insert data in the ldap we get the following error:
[LDAP: error code 80 - entry store failed]
There however seems to be no problem with the login though, this occurs only
during registration

Actually this can all be simplified even further if you're building
--without-threads - in that case, the only WAKE_LISTENER call that matters is
the one made from the signal handler. In every other case, the calling
function will eventually return and fall back into the main event loop anyway.

Yes, at least two things:
- one CPU is about at 100%
- logs from slapd.1.log and slapd.2.log are slowly increasing
It seems to be an infinite loop between the first slapd and the second
slapd, where the second is always active.
I'm sorry I won't be able to access the logs until Tuesday, and all the
processes are now killed.

The X-ORDERED flag obviously cannot be added to existing schema elements; you
need to define a new attribute.
