Sure. What is OpenLDAP 3.2.7? And the bug reported here was already fixed
in OpenLDAP 2.4.9 IIRC. Please validate bugs against 2.4.9 before filing
an ITS.

Thanks for the followup. We'll close this and #5501 with 2.4.10.

Just to feedback on this bug: we have been running packages from CVS
HEAD dated 2008-05-14 on our client setup (which is basically openldap
2.4.9 plus fixes for ITS#5503 and ITS#5506), and I am pleased to report
that we have had no more core files produced since the packages were
installed in the middle of last week.
I'm happy for this ticket to be closed, plus I would suggest closing
ITS#5501, which since it hasn't occurred since, is likely to be another
symptom of this bug.
Thanks once again for your help,
Mark.

I replied to #5525 that a patch for this is now in HEAD. Please test.
I've now closed #5525 as a dup of this bug.

It's not clear that this feature is safe for use. It's certain that indexing
for component matching in back-bdb is broken. Unindexed matching may or may
not work. The lead developer on this feature is gone, so until someone else
comes along to adopt the code it's going to remain DEVEL-only.

A fix is now in HEAD, please test. The solution sets ld_defconn to NULL, and
also closes ld->ld_sb if necessary. In that case, ldap_send_initial_request
will create a new defconn before calling ldap_send_server_request.

Permission denied while opening odbcinst.ini
by Andreas Backman
Hi all!
I'm trying to configure an OpenLDAP server with a mySQL server as back-end.
This is what happens when i try to start the server.
root@ldap:~# slapd -d1
---------
backsql_open_db_handle(): SQLConnect() to database "MySQL" failed.
Return code: -1
nativeErrCode=0 SQLengineState=IM002 msg="[unixODBC][Driver Manager]Data
source name not found, and no default driver specified"
---------
I couldn't find anything wrong with my configuration (see odbc.ini and
odbcinst.ini below) so i tried strace:
root@ldap:~# strace -o /tmp/out.txt slapd
root@ldap:~# grep odbc /tmp/out.txt
open("/usr/lib/libodbc.so.1", O_RDONLY) = 3
open("/etc/odbcinst.ini", O_RDONLY) = -1 EACCES (Permission denied)
access("/etc/odbc.ini", F_OK) = 0
stat64("/etc/odbc.ini", {st_mode=S_IFREG|0644, st_size=598, ...}) = 0
open("/etc/odbcinst.ini", O_RDONLY) = -1 EACCES (Permission denied)
Permissions of odbc.ini and odbcinst.ini
root@ldap:/etc# ls odbc*.ini -l
-rw-r--r-- 1 root root 598 2008-05-23 08:50 odbc.ini
-rw-r--r-- 1 root root 549 2008-05-23 08:49 odbcinst.ini
Contents of my odbc.ini and odbcinst.ini:
odbc.ini:
---------
[MySQL]
Description = MySQL test database
Driver = MySQL
SERVER = 192.168.100.38
USER = root
PASSWORD = ***
PORT = 3306
DATABASE = kplatsen
----------
odbsinst.ini
----------
[MySQL]
Description = MySQL driver for Linux & Win32
Driver = /usr/lib/odbc/libmyodbc3.so
Setup = /usr/lib/odbc/libmyodbc3S.so
FileUsage = 1
[Default]
Driver = /usr/lib/odbc/libmyodbc.so
UsageCount = 1
----------
I've tested the ODBC-connection with:
root@ldap:~# isql MySQL
and it works...
Please help!

Thanks for tracking this down Paul. I think you've nailed it for us, we should
be able to patch this pretty soon.
