Initial setup confusion
by Luke Biddell 17 Mar '09

17 Mar '09

I'm attempting to run openldap on intrepid ibex and am encountering some problems which are most likely down to my understanding. So any newbie help is much appreciated. The first confusion is slapd.conf versus slapd.d. I don't have a slapd.conf file to start with and /etc/ldap/slapd.d is empty. So should I hand-craft a slapd.conf (despite the docs saying this is the old way) and convert it to slapd.d format or do I create an ldif file and put it somewhere (presumably in slapd.d or ldapmodify it)? I've also got a schema I wish to import and currently I'm ldapmodify-ing it in, it's of this form. dn: cn=schema,cn=config changeType: modify add: olcAttributeTypes olcAttributeTypes: ... dn: cn=schema,cn=config changeType: modify add: olcObjectClasses olcObjectClasses: .... ... As you can see I'm adding custom attribute types and object classes into cn=schema,cn=config and this appears to work fine, however they are not persisted across slapd restarts. I presume I need to put them under cn=mycustomconfig,cn=schema,cn=config and then they will persist? I'm sure I'm just missing something fundamental here. More coffee is probably needed. TIA for any help. Luke

Openldap cookie synchronization
by Mihai Stanescu 16 Mar '09

16 Mar '09

Hello all I am developing a service to replicate openldap changes to another server. For this i am using cookie based search with a certain polling interval (10 secs) My problem occurs when there are many changes to be synced from openldap while openldap is under modification stress. Sometimes openldap returns all the entries of the openldap database to my cookie search (i am not reseting the cookie). Later on after the processing is finalized even a single modification in openldap triggers a situation in which cookie based search fetches all the entries of the openldap database. I am not altering the cookies between searches. Does anyone have any idea why this could happen? Is it nomal behavior or a known issue? Could it be a configuration problem? Thanks Mihai

smbk5pwd - slapd stops responding
by Eduardo Sachs 15 Mar '09

15 Mar '09

Hi People, I use the overlay smbk5pwd for sync password of Samba with the of Heimdal Kerberos. In Debian Etch using Samba 3.0.24-6etch10, OpenLDAP 2.3.30-5+etch2 and Heimdal Kerberos 0.7.2.dfsg.1-10, I don't have problems. But, in Debian Lenny using Samba 2:3.2.5-4, OpenLDAP 2.4.11-1, and Heimdal Kerberos 1.2.dfsg.1-2.1, I have problems. When I invoke smbpasswd or ldappaswd and trying change the password, slapd stops responding. With kpasswd I do not have problems, change the password of Samba and Kerberos correctly, and userPassword fixed with {K5KEY}, slapd not stops responding (working correctly), but, I need change the password with smbpasswd for Windows clients. Below follows a more detailed debug, has something else that I can show? This is a bug? slapd.conf configuration: moduleload smbk5pwd overlay smbk5pwd smbk5pwd-enable krb5 smbk5pwd-enable samba smbk5pwd-must-change 2592000 password-hash {K5KEY} - OpenLDAP have permission to read/write the file /var/lib/heimdal-kdc/m-key. - I configure OpenLDAP to run with user root and group root, for tests. smb.conf configuration about password: ldap passwd sync = Only unix password sync = no Look this example: 1 - LDAP OK: root# ps aux|grep slapd root 3841 3.0 0.8 21920 4512 ?

Hostname does not match common name problem
by Sascha 14 Mar '09

14 Mar '09

Hi there! I have a problem with an LDAP server that I need to connect to. I have the required certificate stored on the client but I am getting the following error message: "TLS: hostname (A.xyz123.com) does not match common name in certificate (*.xyz123.com)" Is there any way to work around this problem? As far as I understand it, RFC4514 section 3.1.3 allows wildcards thus the connection should work, shouldn't it? What is confusing me is that "openssl s_client -connect A.xyz123.com:636 -CAfile /etc/ssl/certs/rootca.cer" results in: Verify return code: 0 (ok) If I am not mistaken, openssl accepts the server based on the certificate but openldap does not. Any help is much appreciated. I am really stuck with this. Thanks. Regards, Sascha -- Psssst! Schon vom neuen GMX MultiMessenger gehört?

CPU IOWAIT
by Sergio Cioban Filho 14 Mar '09

14 Mar '09

Hi all, I have 2 openldap servers running on CentOS 5.2 (openldap-2.4.11 RPM: http://staff.osuosl.org/~jeff/openldap/el5/i386/<http://staff.osuosl.org/%7Ejeff/openldap/el5/i386/>), the single-master replication works fine, but when I have activated mirrormode, any ldap interaction is so slowly and CPU IOWAT is 100% (in ldapsearch or ldapadd...). I have tried the same configuration with openldap-2.4.15 + db-4.7.25, but this problem still occurred. Have any idea about this problem? ** Sorry for my poor english... :) Thanks, Regards, --- Sergio Cioban Filho

newbie question: No anonymous authentication = problems
by Andreas Brudin 13 Mar '09

13 Mar '09

Hi, I hope I am on the right list for questions like this. I manage a OpenLDAP server installation on Ubuntu 8.10, and when I upgraded from 8.04 the configuration changed quite a bit. I am trying to turn off anonymous access, but I get problems connecting to the ldap database even when not using anonymous bind. I managed to find the configuration options I was looking for (at least i think so) with phpldapadmin. I found an object with dn olcDatabase={1}bdb,cn=config, in which I found an attribute called olcAccess, which I think is what I need to change. From the beginning it said: {0}to attrs=userPassword,shadowLastChange by dn.base="cn=manager,dc=mydomain,dc=com" write by anonymous auth by self write by * none {1}to dn.base="" by * read {2}to * by dn.base="cn=manager,dc=mydomain,dc=com" write by * read (of course with my dc values). I tried to change the last entry to by * none, as I do not right now need my users to be able to read their or other users' values. It worked as expected, from an LDAP point of view, I still could log in anonymously, but I could not browse the database, however, logged in as manager it worked as it should. The problem came in postfix, because I use my LDAP database (among other things) as an alias table. So I configured postfix not to bind anonymously, but to use server_host = localhost server_port = 389 search_base = dc=mydomain, dc=com bind = yes bind_dn = cn=manager, dc=mydomain, dc=com bind_pw = mysecret result_attribute = mail query_filter = (|(uid=%s)(mailAlias=%s)) But I got dict_ldap_lookup: Search error 50: Insufficient access from the mail.log When I changed back, it worked again. I have tried to change various things (such as put in by anonymous auth before by * read, and changing dc.base="..." to dc="..." both in the first and in the last attribute value above, but it does not seem to change. What am I doing wrong? Any help would be much appreciated. Best regards, Andreas
