Build mdb tools
by "POISSON Frédéric" 21 Mar '14

21 Mar '14

Hello, I'm trying to build mdb tools (mdb_stat and mdb_copy inside libraries/liblmdb directory) on a Solaris 10 SPARC operating system with OpenLDAP 2.4.39. Is there some requirements for building the tools on this OS because i have a error during build ? Here is my result (while i do not set any specific gcc flags) : # make ... gcc -pthreads -O2 -g -W -Wall -Wno-unused-parameter -Wbad-function-cast mdb_stat.o liblmdb.a -o mdb_stat Undefined first referenced symbol in file fdatasync liblmdb.a(mdb.o) ld: fatal: Symbol referencing errors. No output written to mdb_stat collect2: ld returned 1 exit status *** Error code 1 make: Fatal error: Command failed for target `mdb_stat' # Notice that i use a gcc 3.4.3 and gcc option "-pthread" do not exist for this gcc release, i had to replace it by "-pthreads". I try to read mdb.c for any specific options but i don't find anything... Notice also that i succeed to build OpenLDAP 2.4.39 with my Solaris 10 environment. Thanks, -- Frederic Poisson

Hello, Thanks for the answer, i build it without errors. I have patched the Makefile by for my Solaris 10 with gcc 3.4.3 : - replacing "-pthread" by "-pthreads", - add "-lrt" to OPT parameter.

Re: Slave not able to update master pwdFailureTime via chain.
by Esteban Pereira 20 Mar '14

20 Mar '14

I've never configured this kind of architecture, but as far as I know the ppolicy, I think my first thought configuring this would have been to not rebind as user because the attribute modified is an operational one which need the manage right (not sure about that) So I should have configured this with the replication user with manage right and without rebinding as a user when chaining to the master.

Cups Schema
by Borresen, John - 0442 - MITLL 20 Mar '14

20 Mar '14

Hopefully, someone can point me in the correct direction. Forgive me if this falls into the category of "What is the color of George Washington's white horse?" But, I want to do this in the correct way. Using this schema: # Definitions for a schema to store CUPS printer information in LDAP # OID Base is iso(1) org(3) dod(6) internet(1) private(4) enterprise(1) me(5323) cupsSchema(22) # Syntaxes are under 1.3.6.1.4.1.5323.22.0 # Attributes are under 1.3.6.1.4.1.5323.22.1 # Object Classes are under 1.3.6.1.4.1.5323.22.2 attributetype ( 1.3.6.1.4.1.5323.22.1.1 NAME 'printerDescription' DESC 'Description of Printer' EQUALITY caseExactMatch SINGLE-VALUE SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) attributetype ( 1.3.6.1.4.1.5323.22.1.2 NAME 'printerURI' DESC 'CUPS style URI for printer' EQUALITY caseExactIA5Match SINGLE-VALUE SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 ) attributetype ( 1.3.6.1.4.1.5323.22.1.3 NAME 'printerLocation' DESC 'Identifier string for Printer Location' EQUALITY caseExactMatch SINGLE-VALUE SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) attributetype ( 1.3.6.1.4.1.5323.22.1.4 NAME 'printerMakeAndModel' DESC 'String CUPS uses to figure out driver' EQUALITY caseExactMatch SINGLE-VALUE SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) attributetype ( 1.3.6.1.4.1.5323.22.1.5 NAME 'printerType' DESC 'Integer CUPS uses to figure out type' EQUALITY integerMatch SINGLE-VALUE SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 ) objectclass ( 1.3.6.1.4.1.5323.22.2.1 NAME 'cupsPrinter' SUP top AUXILIARY MUST ( printerDescription $ printerURI $ printerLocation $ printerMakeAndModel $ printerType ) ) There is no Structural ObjectClass defined specifically in this schema. Would I use the same ObjectClass as I used to define Hosts, it is a network device. Thanks, John D.

Slave not able to update master pwdFailureTime via chain.

OpenLDAP 2.4.23-26 on CentOS 5. I am trying to get the pwdFailureTime updated on the master when the slave recieves a password failure. Here is my config. It's pretty simple and basic. No TLS.

Hi folks! I wonder if, with the increased interest on mdb, the support for bdb will be removed in a near future. Thanks a lot.

openldap 2.4(slave) replication to openldap2.3(provider not working
by Andrew Belford 19 Mar '14

19 Mar '14

Hi All I have just registered on the mail list seeking for assistance of how to get openldap replication working between 2.3 and 2.4 openldap. My provider is running on 2.3(openldap) which replicates successfully to a 2.3(openldap slave). Recently we build a rhel6 host that comes with openldap 2.4 with the intention to run openldap on it as slave. I have stand up the new slave(2.4 openldap) using the same configuration of the other running slave(2.3openldap) I have managed to slapadd the ldif of the master to the new slave slapadd -l /tmp/AAA01_20140314.ldif However, if I try and search for entries, it shows the following but I am expecting 32K objects [root@vm-nix-t01 ldap]# ldapsearch -x -h 127.0.0.1 "Objectclass=*" 1:1 # extended LDIF # # LDAPv3 # base <> (default) with scope subtree # filter: Objectclass=* # requesting: 1:1 # # search result search: 2 result: 32 No such object I also don't see any replication details in /var/log/slapd.log Could you please show me some troubleshooting directions here regards

Do you expect the statement in slapd-bdb(5), "hdb is the recommended primary database backend," to be revised and/or relaxed in 2.4? Based on the man pages, there are some who read the inverse to be true, that mdb is not (yet) recommended as the primary database backend, or even a reliable option. Or is that still the case? My current read from this discussion is that the recommendation has already flipped, but not yet officially in the documentation. Just wanted to make sure.

LDAP Manager
by Julien Courtès 19 Mar '14

19 Mar '14

Hey, I want to know if it's possible to setup manager in LDAP. I mean an user can have access to others account and change informations such as password for example. One manager can have rights on 2 users to change password. But the manager don't have rights to change informations of other users and only have rights in a single OU. Do I have to use ACL or there is an other way to do it? Thanks, Julien Courtès

Debian makes very specific decisions to: a) Not update what they ship to address known issues (The debian openldap package list is littered with bug reports with pointers to the upstream ITSes) b) Link to a TLS implementation that is known to be utterly flawed (<https://symas.com/software-design-and-trustworthiness/>) So don't try and lecture me about the decisions made by Debian. What they ship is crap, and what they ship could be fixed to not be crap.
