slapd makes very strange troubles in VServer
by Niki Hammler 29 Aug '07

29 Aug '07

Hi, Today I began to move my LDAP-Server to a Linux VServer jail. On the host and on the VServer I run Debian etch 4.0. Installing slapd was no problem (aptitude install slapd). I just copied all configuration and data files from the host which worked perfectly before and copied them 1:1 into the VServer. slapd starts without any warnings. But connecting with a client is not possible, neither inside the VServer nor outside. For security reasons, I just allow access with SSL or TLS-required (the very same file worked greatly on the host!): pidfile /var/run/slapd/slapd.pid argsfile /var/run/slapd/slapd.args loglevel 0 disallow bind_anon require authc security tls=1 TLSCACertificateFile /etc/ldap/ssl/cacert.crt TLSCertificateFile /etc/ldap/ssl/ldap.crt TLSCertificateKeyFile /etc/ldap/ssl/ldap.key TLSVerifyClient never All key files and database files are accessible by slapd (user=openldap, group=openldap). Connecting to ldap and ldaps works greatly from inside the VServer and also from outside: $ nc 192.168.0.2 ldap ^c $ nc 192.168.0.2 ldaps ^c $ There are no packet filters installed, debugging with tcpdump (local interface) shows the complete TCP traffic and handshake with no errors. The strange error is always the same: The clients do not want to connect, sending SSL stuff is always possible but after that, nothing is received. Let's begin with plain SSL: $ openssl s_client -connect 192.168.0.2:636 -debug CONNECTED(00000003) write to 0x80bee90 [0x80bf4e8] (118 bytes => 118 (0x76)) 0000 - 80 74 01 03 01 00 4b 00-00 00 20 00 00 39 00 00 .t....K... ..9.. 0010 - 38 00 00 35 00 00 16 00-00 13 00 00 0a 07 00 c0 8..5............ 0020 - 00 00 33 00 00 32 00 00-2f 03 00 80 00 00 05 00 ..3..2../....... 0030 - 00 04 01 00 80 00 00 15-00 00 12 00 00 09 06 00 ................ 0040 - 40 00 00 14 00 00 11 00-00 08 00 00 06 04 00 80 @............... 0050 - 00 00 03 02 00 80 f5 5d-10 d2 64 21 24 0c b1 c3 .......]..d!$... 0060 - 92 37 72 7a 4a 9c 09 88-46 b2 f8 39 ef f6 c4 c8 .7rzJ...F..9.... 0070 - 84 74 8e a6 79 e1 .t..y. read from 0x80bee90 [0x80c4a48] (7 bytes => 0 (0x0)) 20500:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:188: $ I did lots of tests with many LDAP clients (ldapwhoami, ldapsearch commandline tools, PHP, Softerra LDAP Administrator and Clients in exim4, Courier etc).

As said, all SSL files are accessible and there are no errors in the logs or when starting slapd with '-d'. The certificates CN is exactly the hostname. I'm very frustrated because I can't find any errors. I repeat: the very same configuration worked perfectly on the host system. Is this a bug? Thank you very much in advance for any advice, Niki

The above sentence is not clear to me; what does the trace below refer to? Your original application, or the one that calls ldap_get_option before spawning threads? What does ldap_ld_free() have to do with this? It never occurs in the trace below. > I addition, I won't call ldap outside my thread. Doesn't matter.

Be careful of the LDAP libraries on debian. If they get loaded, you are in trouble, since they are hacked to touch Gnu TLS, and you'll get all sorts of fun.

(ITS#5110) back-ldap, proxy authentication fails when chasing referrals
by f.huiskens＠science-computing.de 28 Aug '07

28 Aug '07

Full_Name: Florian Huiskens Version: 2.3.30 OS: Ubuntu 7.04 URL: Submission from: (NULL) (85.216.39.101) I try to set up an environment, where a client communicates with an LDAP-Proxy. The Proxy forwards the client's query (using the ldap-backend) to an LDAP-Slave. The authentication mechanism I use (proxy - slave) is SASL (GSSAPI). The proxy has a kerberos ticket available. Proxy Authentication works in general (using PROXAUTHZ), but fails on referrals (though rebind-as-user is set). This means that if information is written and the proxy receives a referral to the master, the bind-informations gets lost. Thanks for any help, regards Florian Config-files: Master: include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/nis.schema include /etc/ldap/schema/inetorgperson.schema pidfile /var/run/slapd/slapd.pid argsfile /var/run/slapd/slapd.args loglevel 0 # Where the dynamically loaded modules are stored modulepath /usr/lib/ldap moduleload back_bdb moduleload syncprov # The maximum number of entries that is returned for a search operation sizelimit 500 # The tool-threads parameter sets the actual amount of cpu's that is used # for indexing. tool-threads 1 backend bdb checkpoint 512 30 ####################################################################### # Specific Directives for database #1, of type bdb: # Database specific directives apply to this databasse until another # 'database' directive occurs database bdb suffix "dc=idm,dc=local" # rootdn directive for specifying a superuser on the database.

Thanks My application is multithread. I've had a call to ldap_get_option(NULL, LDAP_OPT_API_INFO, &ldapi) before spawning threads, but here the crash occurred also in ldap_initailize but in ldap_ld_free(). I addition, I won't call ldap outside my thread.

(ITS#5109) ldap_int_global_options not initialized
by damien.doiselet＠neolane.com 28 Aug '07

Full_Name: Damien Doiselet Version: 2.3.30 OS: Debian 4 (kernel 2.6.20.7) URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (82.243.24.157) I'm developing an application which use openldap. I load the library at the runtime with function GetProcAddress My application work correctly except on one PC. This PC is a Debian 4.0 with a kernel 2.6.20.7. Ldap library is a 2.3.30. The library crash, and so my code too in ldap_initialize() (first call of a ldap function): #0 0xb7eab3a3 in strlen () from /lib/tls/i686/cmov/libc.so.6 #1 0xb3a2d1f9 in ber_strdup_x (s=0x6a626f28 <Address 0x6a626f28 out of bounds>, ctx=0x0) at memory.c:640 #2 0xaddcbdf6 in ldap_charray_dup () from /usr/lib/libldap-2.3.so.0 #3 0xaddc2773 in ldap_url_dup () from /usr/lib/libldap-2.3.so.0 #4 0xaddc2802 in ldap_url_duplist () from /usr/lib/libldap-2.3.so.0 #5 0xaddab4dc in ldap_create () from /usr/lib/libldap-2.3.so.0 #6 0xaddab7d1 in ldap_initialize () from /usr/lib/libldap-2.3.so.0 While I was debugging, ldap_int_global_options was not initialized. Nevertheless, with -lldap compilation with gcc, there is no problem.

Does libldap.so.2 still exist in the latest version of open-ldap, and if not, what could other applications link to instead?
by Oliver de Peyer 27 Aug '07

I am trying to install PINE on Fedora 7 (and hey, why not? It's good enough as a command line email program) So, I get hold of Pine-4.64-1-i386.rpm from the UW website. But when I try to install this with rpm, it told me I was missing various dependencies. I managed to download these one by one until I got to one called libldap.so.2. I got as far as working out that this is part of open-ldap. open-ldap.2.3.38 was the latest version I could find and it installed fine - I know it installed OK because the test scripts etc. run OK. But, libldap.so.2 is NOT THERE!! For instance, from the /../ directory, find -name libldap.so.2 -print doesn't find anything (but find -name *so.2 -print does, so there definitely are similarly named files around) I searched for libldap.so.2 in the open-ldap archives and all references to it were a few years ago. It seemed quite possible to me that libldap.so.2 has perhaps been renamed as something else in recent versions of open-ldap. Plenty of other libraries were created when I installed open-ldap.2.3.38, just not one with the exact name libldap.so.2. Is this some finickity requirement of PINE? I have got Apt installed but I don't really know how to use it - can I go look for something as specific as a .so.2 library file? So, what would people suggest? Can I get hold of this file for PINE or persuade it to use something else? (and if so, what and how?) Out of interest, why is PINE interested in libldap.so.2 in the first place and what does it do? Thanks in advance, Sarpeyer

I kind of think they ought to be documented differently, so that people don't confuse SIDs with RIDs (as often happened in OpenLDAP 2.2) but it's probably fine the way it is. -- -- Howard Chu Chief Architect, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
