Translucent overlay search fails with TLS "cannot find private key for certificate"
by Ernie Kovak 22 Sep '15

22 Sep '15

Hello - I'm running openldap 2.4.39 on centos 7, using the translucent overlay and moznss for connections to the backend Active Directory server. When I issue a search request for users in the backend directory I get no results and a "server not available" error - see the debug output below. The same slapd.conf configuration, but on centos 5.10 and using OpenSSL, works correctly. So, I imagine it's related to moznss. I've verified (firewall logs) that openldap successfully connects to the backend on startup, but not when the search request is submitted. It looks like it's trying to use client-authenticated TLS, even though the backend is not set up for that?? Any ideas? Thanks!

funny error
by Fischer, Johannes 22 Sep '15

22 Sep '15

Hi, I’ve just had some funny moments with openldap. I had some bad written code (from my self ☺) where I’ve tried to set a description (2.5.4.13) attribute with an empty string (“”). The result was a error massage: description: value #0 invalid per syntax the best Thing about that is, that the Spring security framework interpreted the error for a following Boolean attribute. This is only for your amusement and to help other with similar problems Greetings John

Hello, centos 6.5 with a basic slapd setup; internal LDAP and proxy to external LDAP Getting segaults every 6 hours or so when I let QA on system and generate some typical user load. All 32 threads halt; ldapsearch stops responding. Typically no logs; last one dropped this: ie: Sep 18 07:47:58 maryann2 kernel: slapd[53754]: segfault at 7f3083ffff98 ip 00007f3104cc3532 sp 00007f30a5ff9660 error 6 in libc-2.12.so [7f3104c4a000+18b000] Should i just sledgehammer a yum update and get off centos 6.5? *Jason K Cafarelli* Desk: (508) 637-5705 (primary) Mobile: (508) 215-9712 jason.cae(a)gmail.com

HDB compared with LMDB
by Philip Colmer 17 Sep '15

17 Sep '15

We're currently using OpenLDAP 2.4.38 on our production server using HDB as the database type. I wanted to upgrade to the latest version and take advantage of LMDB as the database type so I've built a second server and transferred the data. Before making that server the production server, we're running performance comparisons, using ldclt[1] as a stress test tool. I don't know if anyone else has got any experience of using this tool; the output we're getting when running the tool doesn't show significant differences in performance, but I'm not sure if it is just the test type we're running or the fact that, actually, we shouldn't be expecting significant differences ... I've included the output below. I've removed the details of our servers from the command line. Can someone who has made a transition from HDB to LMDB give an indication of whether or not we should see a performance difference on LDAP queries and, if yes, by what sort of factor? If you are familiar with ldclt, should we be running different tests to get a better insight into how the two servers compare? Thanks.

ldap_result timeout not working?
by Ilja Maki 17 Sep '15

17 Sep '15

Hi, What am I missing as the ldap_result function does not seem to care at all about the timeout value given to it? I would need polling behavior and I have tried to give it a timeval of zero, 2 seconds and other small values but often it does not return until over a minute has passed. I have also tried to call ldap_set_option( m_ldap, LDAP_OPT_TIMEOUT, &timeout ) first where the timeout has been zero, 2 seconds etc. but it does not have any effect either. Sometimes ldap_result takes very long also after a call to ldap_simple_bind but usually this happens after a call to ldap_search_ext. Also abandoning a lengthy ldap_result operation is not an option as ldap_result will throw an access violation if it is given an abandoned message identifier. And without access to the internals of the ldap library I cannot synchronize the abandoning so that it would take place only after ldap_result has proceeded so far that it is ok for it to abandon the identifier. My code used OpenLDAP version 1.168.2.16 where this issue occurred, then I upgraded it to version 2.4.42 to see if it behaves differently (with #define LDAP_DEPRECATED 1 for now for simplicity) but the same issue seems to be there. I am developing and testing with Windows 8.1 but the same issue is also at least in Mac OS. Any help will be greatly appreciated.

Strange aliases behavior
by Karol Chrapek 17 Sep '15

17 Sep '15

I have a problem with Slapd and Alias dereferencing. In the ldap we have created a special subtree that allocate logical structure for our application. For this purpose we use the aliases. They allow us in one subtree have normal structure used by our internal services and for second subtree has a dedicate logical structure for special apps. Currently we tested different version of ldap: - 2.4.28 with HDB - 2.4.31 with HDB and MBD - 2.4.41 with mdb - 2.4.42 with MDB <--- this version we are currently using On all version the dereferencing aliases is works very fast when we have about 2000 aliases and about 200000 entries in the Database. When we add additional 2000 aliases each search with aliases dereferencing hangs for 3 second. When we add additional 2000 (so 6000 alieases in DB) the search time increase for next 3 seconds. I.E. search time for filter objectclass=user with -a always for: -2000 aliases in DB is about 0,031s -4000 aliases in DB is about 3,031s -6000 aliases in DB is about 6,123s And this search time was increase even if we add additional 2000 aliases outside the search base dn. We observed that during this 3, 6 second hangs one CPU core is about 100%, system does not wait for resources, memory is on the same level. In the log I saw that slapd very fast dereferencing all aliases in subtree, hang for 3,6,9 seconds depends of aliases count and after that I saw: mdb_dn2entry("cn=.....")

OpenLDAP wildcard searches.
by Michael 16 Sep '15

16 Sep '15

Hello all, I've come across an issue where java developers using one of our LDAP environments want to be able to do wildcard searches on non-standard LDAP attributes. They are using a custom schema in the LDAP environment which contains the following attributes for example. retailerId:jurisdictionID: They want to be able to perform the following search filter to pull all entries with 21 as the jurisdictionID and any wildcard for the retailerID. '(&(retailerId=*)(jurisdictionID=21))' works as expected but of course this returns all objects with any retailerID. They would like to narrow the search results using the filters below. Is there something that needs to be added to the custom schema to allow this to work like it does for the standard LDAP attributes like cn,sn,mail etc? '(&(retailerId=177*)(jurisdictionID=21))' returns zero results'(&(retailerId=*389)(jurisdictionID=21))' returns zero results'(&(retailerId=1*389)(jurisdictionID=21))' returns zero results

Configuring OpenLDAP server with Linux groups information
by JC 15 Sep '15

15 Sep '15

I have a CentOS system where authentication over the SSH interface is delegated to an OpenLDAP server by means of PAM. This works fine. However, when the authentication succeeds, I would like for the OpenLDAP server to send back group information as well to the CentOS system. That is, the OpenLDAP server should send back a list of groups that the authenticated user will belong to when a shell is created for it in the CentOS box. This information should supersede what groups information local to the CentOS box. I have an LDAP schema in the OpenLDAP server system that almost achieves what I want - but not quite. In the CentOS system I currently have a file named mysite.ldif with the following contents: # extended LDIF## LDAPv3# base <dc=mysite,dc=com> with scope subtree# filter: (objectclass=*)# requesting: ALL# # mysite.comdn: dc=mysite,dc=comobjectClass: topobjectClass: dcObjectobjectClass: organizationo: MySitedc: mysite # People, mysite.comdn: ou=People,dc=mysite,dc=comou: PeopleobjectClass: organizationalUnit # Group, mysite.comdn: ou=Group,dc=mysite,dc=comou: GroupobjectClass: organizationalUnit # firstgroup, Group, mysite.comdn: cn=firstgroup,ou=Group,dc=mysite,dc=comobjectClass: posixGroupobjectClass: topcn: onegroupuserPassword:: e2NyeXB0fXg=gidNumber: 1001memberUid: FirstUsermemberUid: SecondUser # secondgroup, Group, mysite.comdn: cn=secondgroup,ou=Group,dc=mysite,dc=comobjectClass: posixGroupobjectClass: topcn: twogroupuserPassword:: e2NyeXB0fXg=gidNumber: 1002memberUid: FirstUser # FirstUser, People, mysite.comdn: uid=FirstUser,ou=People,dc=mysite,dc=comuid: FirstUsercn: FirstUserobjectClass: accountobjectClass: posixAccountobjectClass: topobjectClass: shadowAccountshadowLastChange: 14250shadowMax: 99999shadowWarning: 7loginShell: /bin/bashuidNumber: 1014gidNumber: 1014homeDirectory: /home/FirstUsergecos: ,,,userPassword:: TXlQYXNzd29yZAo= # SecondUser, People, mysite.comdn: uid=SecondUser,ou=People,dc=mysite,dc=comuid: SecondUsercn: SecondUserobjectClass: accountobjectClass: posixAccountobjectClass: topobjectClass: shadowAccountshadowLastChange: 14002shadowMax: 99999shadowWarning: 7loginShell: /bin/bashuidNumber: 1005gidNumber: 1005homeDirectory: /home/SecondUsergecos: ,,,userPassword:: T3RoZXJQYXNzd29yZAo= After starting my OpenLDAP server, I load this information into the OpenLDAP server's database with ldapadd -D uid=root,ou=People,dc=mysite,dc=com -x -w ThePassword -f mysite.ldif Now assuming that LDAP authentication is enabled in the Linux server, and that PAM in this system will delegate its authentication to the OpenLDAP server above, the authentication works fine (assuming the correct password is entered, of course) but the groups information does not seem to be extracted correctly. After successfully logging in as users FirstUser, if from the command line I invoke groups FirstUser I get the following output: FirstUser : user onegroup onegroup twogroup twogroup I do not understand why 'onegroup' and 'twogroup' are repeated. For completeness, the /etc/nsswitch.conf file in the CentOS system contains (among other things) the following line: group: ldap [SUCCESS=return] files Any feedback on this issue will be welcome. It should be clear by now that I am not, by any means, an expert on things LDAP; my apologies if I am doing something stupid or misguided.
