Unknown db in slapd.conf
by espeake＠oreillyauto.com 03 Oct '13

03 Oct '13

I have a brand new Ubuntu-12.04 server with a brand new build of openldap 2.4.36 on it and I am try to set it up for MMR with mdb. I get the following error when I try slapadd my config. 524c62f1 line 61 (databse mdb) 524c62f1 /usr/local/etc/openldap/slapd.conf: line 61: <database> failed init (mdb)! Now when I look at man slapd.conf and these are the database types that are shown for use. There is nothing there showing mdb, but I know that it is a viable selection. database <databasetype> Mark the beginning of a new database instance definition. <databasetype> should be one of bdb, config, dnssrv, hdb, ldap, ldif, meta, monitor, null, passwd, perl, relay, shell, or sql, depending on which backend will serve the database. in my slapd.conf file I have the following setup (just partially listing here): # Load dynamic backend modules: modulepath /usr/local/libexec/openldap moduleload back_mdb.la moduleload back_ldap.la ############################################################################ database mdb I have checked and double cheked to be sure that /usr/local/libexec/openldap/back_mdb.la exists. What simple thing am I missing?

OpenLDAP duplication
by 25Dollar Tech 30 Sep '13

30 Sep '13

Hello Team, I just want to know the below According to my understanding, LDAP authenticates (binds) with DN (distinguish name) and password. E.g. CN=bob, OU=Users,DC=test,DC=com. So OpenLDAP allows the same CN in a different OU. Is there any option to prevent it. ? -- *Thanks & Regards, 25dollarTech Team https://sites.google.com/site/25dollartech/* *Email: 25dollartechhelp(a)gmail.com*

ldapsearch: wildcard search do not list all entries
by Birgit Ohlenbusch 30 Sep '13

30 Sep '13

Hello, I had a curious problem with ldapsearch: A wildcard search like ldapsearch -LLL -Wx -h myldap -D cn=xx -b dc=xx -b "ou=Accounts,xx" uid='xyzzs*' uid lists only three entries: dn: uid=xyzzs146,ou=Accounts,xx uid: xyzzs146 dn: uid=xyzzs147,ou=Accounts,xx uid: xyzzs147 dn: uid=xyzzs148,ou=Accounts,xx uid: xyzzs148 though there exists more, which can be displayed with ldapsearch not specifying a filter or by specifying the object exactly like ldapsearch -LLL -Wx -h myldap -D cn=xx -b dc=xx -b "ou=Accounts,xx" uid='xyzzs020' uid Reindexing with slapindex solved the problem, ldapsearch with uid='xyzzs*' shows all those entries, not only three. But I'm afraid that this happens again. Can you tell me how somethink like this can happen and how I can prevent such a situation? The slapd is running on a RHLE 6.4 server, using a hdb database. We indexed olcDbIndex: objectClass pres,eq olcDbIndex: entryUUID eq olcDbIndex: entryCSN eq olcDbIndex: cn pres,eq olcDbIndex: uidNumber pres,eq olcDbIndex: gidNumber pres,eq olcDbIndex: CAUmailHost pres,eq olcDbIndex: memberUid pres,eq olcDbIndex: ou eq olcDbIndex: uniqueMember pres,eq olcDbIndex: uid pres,eq,sub Thanks in advance for your help Birgit

Kudos to all who contributed to MDB
by Brent Bice 30 Sep '13

30 Sep '13

I've started testing an LDAP server here using MDB and ran across a few caveats that might be of use to others looking into using it. But first off, let me say a hearty THANKS to anyone who's contributed to it. In this first OpenLDAP server I've converted over to MDB it's *dramatically* faster and it's definitely nice to not worry about having to setup script/s to occasionally (carefully) commit/flush DB logs, etc. One caveat that might be worth mentioning in release notes somewhere... Not all implementations of memory mapped I/O are created equal. I ran into this a long time back when I wrote a multi-threaded quicksort program for a friend to had to sort text files bigger than 10 gigs and didn't want to wait for the unix sort command. :-) The program I banged together for him used memory mapped I/O and one of the things I found was that while Solaris would let me memory map a file bigger than I had physical or virtual memory for, linux wouldn't. It appeared that some versions of the 2.x kernels wouldn't let me memory-map a file bigger than the total *virtual* memory size, and I think MDB is running into the same limitation. On a SLES11 system, for instance with the 2.6.32.12 kernel, I can't specify a maxsize bigger than the total of my physical memory and swap space. So just something to keep in mind if you're using MDB on the 2.x kernels - you may need a big swap area even though the memory mapped I/O routines in the kernel seem to be smart enough to avoid swapping like mad. On a newish ubuntu system with a 3.5 kernel this doesn't seem to be an issue - tell OpenLDAP to use whatever maxsize you want and it just works. :-) I'd also only use MDB on a 64 bit linux system. One of the other headaches I remember running into with memory mapped I/O was adding in support for 64 bit I/O on 32 bit systems. Best to avoid that whole mess and just use a 64 bit OS in the first place. Lastly... At the risk of making Howard and Quanah cringe... :-) The OpenLDAP DB I've been testing this with is the back-end to an email tracking tool I setup several years ago. More as an excuse to edjimicate myself on the java API for LDAP than anything else, I wrote a quick bit of java that watches postfix and sendmail logs and writes pertinent bits of info into an LDAP database, and a few PHP scripts to then query that database for things like to/from addresses, queue IDs, and message IDs. 'Makes it easy for junior admins to quickly search through gigabytes of logs to see what path an email took to get from point A to point B, who all received it (after it went through one or more list servers and a few aliases got de-ref'd, etc). Yeah, it's an utter abuse of LDAP which is supposed to be write-rarely and read-mostly, especially as our postfix relays handle anywhere from 1 to 10 messages per second on average. :-) But what the heck, it works fine and was a fun weekend project. It's also served as a way to stress-test new versions of OpenLDAP before I deploy them elsewhere. :-) Anyway, thanks again to everyone who contributed to MDB. It's lots faster than BerkeleyDB in all of my testing so far. 'Looking forward to gradually shifting more of my LDAP servers over to it. Brent

building SLES packages on openSuSE Build Service
by Marc Patermann 30 Sep '13

30 Sep '13

Hi, I used to build newer versions of openldap on openSuSE Build Service derived from the ones at network:ldap (from Ralf Haferkamp; which is stuck at .33). I did this for 2.4.33, .34 and .35. When I tried to build 2.4.36 something changed (at the build service?) and now my builds - even the older ones, which built fine before - fail with the following errors: [ 399s] E: openldap2 64bit-portability-issue dn2id.c:738 [ 399s] E: openldap2 64bit-portability-issue id2entry.c:123 What may have caused this?

If the network address of the services used by domain-A users is different from that used by domain-B users then the server processes will know which domain they are serving. If the same network address is used to serve all domains then you do indeed require the uids to be unique across domains (but you probably do want to let fred(a)x.y.com use that ID for all services). > > It may be enough for you to simply prevent the non-uniqueness.

Something like: overlay unique unique_uri ldap:///ou=People,dc=org?uid?sub?(authorizedService=SMTP) unique_uri ldap:///ou=People,dc=org?uid?sub?(authorizedService=IMAP) unique_uri ldap:///ou=People,dc=org?uid?sub?(authorizedService=POP3) unique_uri ldap:///ou=People,dc=org?uid?sub?(authorizedService=XMPP) unique_uri ldap:///ou=People,dc=org?uid?sub?(authorizedService=SSH) Andrew -- ----------------------------------------------------------------------- | From Andrew Findlay, Skills 1st Ltd | | Consultant in large-scale systems, networks, and directory services | | http://www.skills-1st.co.uk/ +44 1628 782565 | -----------------------------------------------------------------------

Building LMDB for Windows 64bits
by Alain 29 Sep '13

29 Sep '13

I am not an expert at this, so I might be doing things incorrectly. I used Mingw x86_64 to build LMDB (just changed the CC in the Makefile). I had an issue with srandom and random in the test programs and switch to rand instead. Now I can build successfully and make test runs mtest successfully. Now if I try one of the other mtest[2-5] or mtest itself, I get sporadic segmentation fault. If I wait long enough it will always work, but running the programs in a kind of loop guarantees a seg fault error. I wanted to try running with gdb but it seems that it doesn't ship with cygwin for Mingw. Using standard gdb gives me a 193 error. Again this is getting past my expertise here. Has anyone successfully build LMDB for Windows and can help here. Cheers, Alain
