2.4.42 RPMs for openSUSE
by Michael Ströder
HI!
I've updated my OpenLDAP builds for openSUSE and SLES12 to release 2.4.42.
Build status and files:
<https://build.opensuse.org/package/show/home:stroeder:branches:network:ld...>
Important note:
If you're using the openldap packages shipped with openSUSE make sure to read
the .changes files to see whether something could break your current setup.
As usual I've tested the packages openSUSE Tumbleweed x86_64 and Factory_ARM
on rasperry pi.
The download repos are here:
<http://download.opensuse.org/repositories/home:/stroeder:/branches:/netwo...>
Make yourself familiar with zypper commands.
Example: Add the repo in openSUSE 13.2 (command in one line):
zypper addrepo --refresh
http://download.opensuse.org/repositories/home:/stroeder:/branches:/netwo...
Please test. Your feedback is appreciated. Especially have a look at whether
the RPMs behave well regarding config files, package descriptions etc.
Compared to stock SUSE packages there are two additional packages:
1. openldap2-contrib with a selection of overlays from, you
might have guessed, the contrib/ source directory:
allop, allowed, autogroup, cloak, denyop, lastbind, noopsrch, nops, pw-sha2,
pw-pbkdf2, smbk5pwd
2. openldap2-back-sock
(see http://www.openldap.org/software/man.cgi?query=slapd-sock)
Ciao, Michael.

send_search_entry: conn xxx ber write failed
by Édnei Rodrigues
Good morning. How are you doing ?
Guys, I have a application that do many connections to my ldap server and I
am getting the error "send_search_entry: conn xxx ber write failed." and
"(connection lost on write)".
This error occur only with that application, but The noise is large,
because this one is very importante.

ldapsearch getting attribute list in specific order
by Craig White
I am surprised I haven't tripped over this before.
ldapsearch -b ou=people, etc. uid pwdChangedTime mail
Wanting to e-mail people with expiring passwords.
I am counting on 4 lines for each person...
Dn:
UID:
pwdChangedTime:
mail:
in this exact order
but on the last one (which happens to be me, perhaps because I was the last one to change my password), my 'mail' attribute was returned before the pwdChangedTime attribute which would cause me to re-write the code to handle randomness of order of the output. Do I have to re-write my bash script?

ldapmodrdn accented characters with windows client
by LAROCHETTE Philippe
Hello,
I can't use ldapmodrdn command when some attributes like givenname contains accented characters, the error is "Rename result: Invalid DN syntax(34)
My configuration is a server with Linux centos 7 and Openldap 2.4.35
The client is a windows XP where i copy the binarie ldapmodrdn.exe from openldap for windows 2.4.32
When i launch this command for example on linux server it is ok but on the xp client it doesn't work :
ldapmodrdn -h xx.xx.xx.xx:389 -D cn=admin,c=fr -w yyyyyy -s "ou=TEST,c=FR" "cn=TEST Véronique,ou=TEST2,c=FR" "cn=Myname Véronique"
I think the problem is with the executable ldapmodrdn.exe. Where can i find an equivalent version of the linux version that can works on windows ? Have you an idea to solve the problem ?
Thanks

basedn vs binddn

Hi,
I am currently referring to http://www.openldap.org/doc/admin24/ I have
still not understood the difference between basedn and binddn. I will
appreciate if somebody can help me understand with some examples.

ldapsearch blocks forever
by Oliver Kowalke
After inspecting the source files of ldapsearch I encountered that
ldap_result() is called with tv.tv_sec = -1. As a result ldap_result()
will block forever (poll() is invoked with -1) in some cases.
If for instance the MTU is no big enough (likely in the context of IPv6
and tunnels), the data will not arrive and ldapsearch will 'hang'.
I'd like to ask what was the intention to call ldap_result() with
tv.tv_sec = -1 even if a timelimit (option -l) was applied at command line.
thx,
Oliver

uniqueness constraint violated when using ldapadd -M
by Geert Hendrickx
Hi,
I noticed uniqueness constraints enforced by the slapo-unique overlay can
be bypassed when using the manage DSA IT control (ldapadd -M).
Using the following simple constraint:
overlay unique
unique_uri ldap:///?mail?sub
I get:
$ ldapadd -x -h localhost -D cn=Manager,dc=my-domain,dc=com -w secret
dn: cn=test1,dc=my-domain,dc=com
objectClass: inetOrgPerson
cn: test1
sn: test1
mail: test(a)my-domain.com
adding new entry "cn=test1,dc=my-domain,dc=com"
dn: cn=test2,dc=my-domain,dc=com
objectClass: inetOrgPerson
cn: test2
sn: test2
mail: test(a)my-domain.com <===== duplicate, violates uniqueness constraint
adding new entry "cn=test2,dc=my-domain,dc=com"
ldap_add: Constraint violation (19)
additional info: some attributes not unique <===== ok, as expected
Retrying with -M
$ ldapadd -M -x -h localhost -D cn=Manager,dc=my-domain,dc=com -w secret
dn: cn=test2,dc=my-domain,dc=com
objectClass: inetOrgPerson
cn: test2
sn: test2
mail: test(a)my-domain.com <===== duplicate, violates uniqueness constraint
adding new entry "cn=test2,dc=my-domain,dc=com" <===== but it is accepted?
$ ldapsearch -x -h localhost -b dc=my-domain,dc=com mail=test(a)my-domain.com
# extended LDIF
#
# LDAPv3
# base <dc=my-domain,dc=com> with scope subtree
# filter: mail=test(a)my-domain.com
# requesting: ALL
#
# test1, my-domain.com
dn: cn=test1,dc=my-domain,dc=com
objectClass: inetOrgPerson
cn: test1
sn: test1
mail: test(a)my-domain.com
# test2, my-domain.com
dn: cn=test2,dc=my-domain,dc=com
objectClass: inetOrgPerson
cn: test2
sn: test2
mail: test(a)my-domain.com
# search result
search: 2
result: 0 Success
# numResponses: 3
# numEntries: 2
The uniqueness constraint has been violated when using -M, while it was
correctly enforced without -M.
Feature or bug?
