OpenLDAP Data Directory issue
by rahul.manchanda＠bt.com 14 Apr '10

14 Apr '10

Hello, For a running LDAP if I delete the data directory still the LDAP is responding to reads and writes without giving any error. All logins in related to application are working fine. Is this picking the data from cache or actual data itself is getting stored somewhere. Can someone please provide his/her technical expertise on this behavior?

Sincronizing two different structred trees
by Rodrigo Renie Braga 14 Apr '10

14 Apr '10

Hello list. I was wondering if it's possible to sincronize, using chaining or syncrepl, two different structured OpenLDAP servers, actually, both servers are equal on a specific sub-tree and it's that specific subtree that I'd like to sincronize. Something like: Server A dc=example,dc=com | | - ou=users | | - ou=company Server B dc=other,dc=org | | - ou=people | | - ou=company It's both "company" subtrees that i'd like to sinc... Is it possible? Thanks in advance...

SASL EXTERNAL, sasldb2 and authz-regexp
by Götz Reinicke - IT-Koordinator 14 Apr '10

Hi folks, first of all thanks to all comments about my previous posts! Finaly I'm faced with hopefully the last authentication problem and may be somewone could tell me an answere or point me once more into the right direction. My consumer server should bind to the provider using sasl with the saslmech external. (Red Hat 5.x, cyrus-sasl-2.1.22, openldap-2.3.43-3 ) I'v changed the slapd.conf files on both servers: consumer: syncrepl ... bindmethod=sasl saslmech=EXTERNAL starttls=yes provider: authz-regexp "dn=email=webmaster(a)filmakademie.de,cn=ldap2.filmakademie.de,ou=it officenet,o=filmakademie baden-wuerttemberg gmbh,l=ludwigbsburg,st=baden-wuerttemberg,c=de" "cn=replicator,dc=filmakademie,dc=de" after restarting both servers I do get the error: <==slap_sasl2dn: Converted SASL name to <nothing> SASL [conn=0] Error: unable to open Berkeley db /etc/sasldb2: No such file or directory I've searched my docs, online howtoos and found postings about "know sasl before using openldap" but the sasl docs didn't help too.

Re: Problem with SSL/TLS
by Chris Jacobs 13 Apr '10

/etc/ldap.conf is used by nss tools and the ilk. /etc/openldap/ldap.conf would be used by openldap tools - like ldapsearch. I have the same setting there for tls_checkpeer - but in the latter ldap.conf (under openldap). FWIW: there's apparently no real different format for the two files; while one would only be setup on ldap servers, mine are identical and things work with a mirror master, both setup behind a VIP (fail over, not load balanced) and a plethora of slaves in different subdomains. - chris PS: I'd forgotten to 'reply-to-all' earlier. :) Chris Jacobs, Systems Administrator Apollo Group | Apollo Marketing | Aptimus 2001 6th Ave Ste 3200 | Seattle, WA 98121 phone: 206.441.9100 x1245 | mobile: 206.601.3256 | fax: 206.441.9661 email: chris.jacobs(a)apollogrp.edu ________________________________ From: Lynn York To: Chris Jacobs Sent: Mon Apr 12 10:29:19 2010 Subject: RE: Problem with SSL/TLS Here is my /etc/ldap.conf: #host 127.0.0.1 base cn=users,dc=testing,dc=com uri ldap://localhost:636 binddn cn=manager,dc=testing,dc=com bindpw password scope sub timelimit 120 bind_policy soft bind_timelimit 120 idle_timelimit 3600 ssl on tls_cacert /etc/openldap/cacerts/servercrt.pem tls_cacertdir /etc/openldap/cacerts tls_checkpeer no nss_base_group cn=groups,dc=testing,dc=com?sub pam_password md5 I have tried it with and without “tls_checkpeer”….

Overlay Chain Extended Passmod Problem
by Ralf Zimmermann 13 Apr '10

13 Apr '10

Hi all, last week I wrote to the list because I have a problem with overlay chain. Today I traced the problem. The configuration and the host are the same. OpenLDAP syncrepl runs fine over the weekend. But if I want to change a password nothing happens. I can't see any packet with tcpdump from the slave to the master. I traced slapd with loglevel=65535. The slave is openldap 2.4.21. # Here the trace with no successfull passmod operation: ----------------------------------------------------- conn=1126 op=1 BIND dn="cn=ldapadmin,dc=camelot,dc=de" method=128 do_bind: version=3 dn="cn=ldapadmin,dc=camelot,dc=de" method=128 => bdb_entry_get: ndn: "cn=ldapadmin,dc=camelot,dc=de" => bdb_entry_get: oc: "(null)", at: "(null)" bdb_dn2entry("cn=ldapadmin,dc=camelot,dc=de") => bdb_entry_get: found entry: "cn=ldapadmin,dc=camelot,dc=de" bdb_entry_get: rc=0 => bdb_entry_get: ndn: "cn=default,ou=policies,dc=camelot,dc=de" => bdb_entry_get: oc: "(null)", at: "(null)" bdb_dn2entry("cn=default,ou=policies,dc=camelot,dc=de") bdb_entry_get: found entry: "cn=default,ou=policies,dc=camelot,dc=de" bdb_entry_get: rc=0 ==> hdb_bind: dn: cn=ldapadmin,dc=camelot,dc=de bdb_dn2entry("cn=ldapadmin,dc=camelot,dc=de") ) # Here the trace after I restart slapd with exactly the same config # and working passmod oepration: ------------------------------------------------------------------ conn=1000 op=1 BIND dn="cn=ldapadmin,dc=camelot,dc=de" method=128 do_bind: version=3 dn="cn=ldapadmin,dc=camelot,dc=de" method=128 => bdb_entry_get: ndn: "cn=ldapadmin,dc=camelot,dc=de" => bdb_entry_get: oc: "(null)", at: "(null)" bdb_dn2entry("cn=ldapadmin,dc=camelot,dc=de") => hdb_dn2id("cn=ldapadmin,dc=camelot,dc=de") <= hdb_dn2id: got id=0x5 entry_decode: "" <= entry_decode() => bdb_entry_get: found entry: "cn=ldapadmin,dc=camelot,dc=de" bdb_entry_get: rc=0 => bdb_entry_get: ndn: "cn=default,ou=policies,dc=camelot,dc=de" => bdb_entry_get: oc: "(null)", at: "(null)" bdb_dn2entry("cn=default,ou=policies,dc=camelot,dc=de") => hdb_dn2id("ou=policies,dc=camelot,dc=de") <= hdb_dn2id: got id=0x9 => hdb_dn2id("cn=default,ou=policies,dc=camelot,dc=de") <= hdb_dn2id: got id=0xa entry_decode: "" <= entry_decode() => bdb_entry_get: found entry: "cn=default,ou=policies,dc=camelot,dc=de" bdb_entry_get: rc=0 ==> hdb_bind: dn: cn=ldapadmin,dc=camelot,dc=de bdb_dn2entry("cn=ldapadmin,dc=camelot,dc=de") When the passmod operation is successfull there are hdb_dn2id entries in the trace. When the passmod operation ist not successfull the entries doesn't exist. What happens, that I must restart the slapd? The configuration is the same and all other things works fine. Only the write operations to the master hangs. If I make a passmod without TLS everything works fine and I can change the password after I restarted the slapd on the slave. Then I can change the passwords the wholy day. Tomorrow I'll must restart slapd on the slave because the passmod operation is not successfull. Any ideas? regards Ralf Zimmermann -- .''`.

SSL / Certificates / ... Some confusion
by Götz Reinicke - IT-Koordinator 12 Apr '10

12 Apr '10

Hi, since a couple of days I try to setup a provider and a consumer over ssl following the documentation in a book [1] an dusing two servers. (Red Hat 5.x, openssl-0.9.8e-12, openldap-2.3.43-3 ) Doing so I was confronted with a lot off different warnings/messages but finaly I got the replication crypted. The final step in the tutorial is to use the saslmech=external but the messages I do get are different from the messages I should get. I noticed and googeled some provider debug info and wanted to ask for some prove or clarification or work around: >From the provider log: TLS certificate verification: Error, unsupported certificate purpose ... TLS trace: SSL3 alert write:warning:bad certificate connection_read(13): unable to get TLS client DN, error=49 id=1 >From a posting from 2006 and the answere from Howard Chu [2] I think I do have the same problem: My consumer server certificate "should be" from the providers view a client certificate. >From the certificate: X509v3 extensions: X509v3 Basic Constraints: CA:FALSE Netscape Cert Type: SSL Server Am I wrong, right, lost, ... Is there a workaround or any step while creating the certificates?

TLS issues
by Daniel Gomes 12 Apr '10

12 Apr '10

Dear list members, I am having some problems with TLS I would like to share and hopefully solve with your help. First of all, the specs: it's a OpenLDAP 2.4.19 compiled (manually, not via apt-get) on a Ubuntu 8.04 (Hardy). I don't think it matters, but I am using the dynlist overlay (that's why I had to compile manually and not via apt-get, as I couldn't get it to work with the package Ubuntu provides). Passing on to the problem itself, let me just start by saying that the SSL/TLS setup itself seems to be working fine, and I am always able to ldapsearch on port 636 with ldaps:// (SSL) or on port 389 with ldap:// and -ZZ (TLS). Unfortunately, using other clients (phpLDAPadmin and some custom php scripts I wrote), the behavior is rather random. Sometimes it fails, sometimes it works (at the beginning it worked more often than not, lately it has been working less and less). The server logs, unfortunately, are not so helpful (for me, at least!). The only error I see (with logs at -1, trying to connect via phpLDAPadmin with TLS on port 389) is: connection_read(15): TLS accept failure error=-1 id=23, closing Apr 7 16:45:18 gold slapd[7385]: connection_closing: readying conn=23 sd=15 for close Apr 7 16:45:18 gold slapd[7385]: connection_close: conn=23 sd=15 Apr 7 16:45:18 gold slapd[7385]: daemon: removing 15 Apr 7 16:45:18 gold slapd[7385]: daemon: activity on 1 descriptor Apr 7 16:45:18 gold slapd[7385]: daemon: activity on: Apr 7 16:45:18 gold slapd[7385]: conn=23 fd=15 closed (TLS negotiation failure) Trying on port 636 with ldaps:// yields the same error. But as I mentioned, it just happen sometimes, while on others the connection is successfully established! Although I did notice that even when it does work, I get the following error: connection_read(14): unable to get TLS client DN, error=49 id=8 but it is quickly followed by a "conn=8 fd=14 TLS established tls_ssf=256 ssf=256"... So, this is my problem and it is getting me quite puzzled... The fact that it does work on occasion makes me think it can't be my configuration or the usual file permission culprit... Here's my slapd.conf (I removed the ACL configuration, as I am guessing it's not important here): # # See slapd.conf(5) for details on configuration options. # This file should NOT be world readable. # include /usr/local/etc/openldap/schema/core.schema include /usr/local/etc/openldap/schema/cosine.schema include /usr/local/etc/openldap/schema/dyngroup.schema include /usr/local/etc/openldap/schema/inetorgperson.schema #Custom Schemas include /usr/local/etc/openldap/schema/local.schema include /usr/local/etc/openldap/schema/postfix.schema pidfile /home/slapd/run/slapd.pid argsfile /home/slapd/run/slapd.args ####################################################################### # Database definitions ####################################################################### database hdb suffix "dc=example,dc=com" rootdn "cn=admin,dc=example,dc=com" rootpw secret directory /home/slapd/database index objectClass eq ####################################################################### # Replication ####################################################################### overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 ####################################################################### # TLS ####################################################################### TLSCipherSuite HIGH:MEDIUM:+SSLv2 TLSCACertificateFile /home/slapd/ssl/cacert.pem TLSCertificateFile /home/slapd/ssl/servercrt.pem TLSCertificateKeyFile /home/slapd/ssl/serverkey.pem TLSVerifyClient never ####################################################################### # Overlay (for dynamic lists) ####################################################################### overlay dynlist dynlist-attrset ipfnRole memberURL member If it helps for anything, in the ldap.conf files of the client I also have the "TLS_REQCERT never" setting, together with the TLS_CACERT and TLS_CACERTDIR for the CA's certificate.
