Upgrade from openldap 2.4.9 to 2.4.12
by Paul Lee 24 Oct '08

24 Oct '08

Dear all, I am currently having 4 LDAP servers running in 4-way masters mode, the current version is 2.4.9 and there are around 100k records. The db version is 4.2. If I want to upgrade to version 2.4.12, I should upgrade the db to 4.4 or above, right ? but if the db version is upgraded, how to preserve my existing 100k records, any formal procedure to convert the data to the new format ? Is my following procedure correct ? - upgrade the db version to 4.4 - upgrade openldap in 1 machine to 2.4.12 - delete all the files in /usr/local/var/openldap-data - stop 2 more openldap servers, leaving only 1 running version 2.4.9 - start the new server running version 2.4.12, then, records will be created in 2.4.12. - repeat for others servers. Is this correct ? Thanks Confidential Communication - This e-mail (including any attachments) is confidential and may be legally privileged.

Security issue : userPassword is shown
by Paul Lee 23 Oct '08

23 Oct '08

Hi all, I use a 3rd party LDAP browser to browse the users that I created. I can see the userPassword clearly (plain text). Is there any way to avoid this ? When I use slapcat command to export to LDIF file, the userPassword field is encrypted, but why using 3rd party browser will show the password in plain text ?

yes. absolutely correct: 2.4.12 needs 4.4+ http://www.openldap.org/software/release/readme.html Rein Tollevik schrieb: > Oliver Liebel skrev: >> keep it simple. >> first, theres no need of upgrading your bdb. >> 4.2.52 has the longest history to be stable. >> for bdb versions, see: >> http://www.openldap.org/lists/openldap-technical/200807/msg00138.html > > As of version 2.4.12, the bdb backend only support db versions 4.4 and > higher.

Case sensitive uid attribute
by Martin Benson 23 Oct '08

23 Oct '08

Hi I am currently using Buchan Milne's OpenLDAP 2.3.43 rpm's on a RHEL 4.4 installation. I use the core, cosine, inetorgperson and NIS schema's and everything works great. I mainly use OpenLDAP as an authentication server and I have a problem where the uid is not case sensitive. If I create a user called "Martin" then it will also allow me to log in as "martin" and then fails as it cannot find my home directory. I have had a look at the schema files and in the core.schema and the core.ldif the uid entry is commented out. It contains an entry "EQUALITY caseIgnoreMatch" and I tried to change it to "EQUALITY caseExactMatch". Now I realise that I shouldn't be touching the core.schema but I don't know how else to do this without invalidating all the entries in the current database. No surprise but changing the attribute and uncommenting the uid entry did not work so any help would be appreciated. Sorry for not including all the usual files like slapd.conf but they are on the server at work and I am at home. Martin Benson

Hello, I have been attempting to use openldap as a proxy to AD with no success. I have attempted multiple different ways that I found online. I am able to get the proxy server to connect to AD, but I cannot get a client server to connect through the proxy to the AD server. Can anyone suggest anything? -Lynn

TLS not working (even though SSL does) -- logging trouble
by Kyle Barger 21 Oct '08

21 Oct '08

I have an OpenLDAP 2.3 server that is up and running. I have been trying to add SSL and TLS. SSL connections on port 636 work fine. However the TLS connection on 389 is not working. The only errors are "TLS accept failure" and "TLS negotiation failure." I've not been able to dig up any more information, even using the -d option, and I notice that people have posted log files with detailed TLS trace messages. How can I enable the TLS logging to find out what's going on? Thanks. -- Kyle Barger Director of Information Systems The Lutheran Theological Seminary at Philadelphia (For questions about your computer, network, or telephone service, email helpdesk(a)ltsp.edu)

Issue while implementing Password Policy
by daljeet.mehta＠wipro.com 21 Oct '08

21 Oct '08

Hi, I am trying to implement password policy in OpenLDAP. There are already similar postings on the same issue. But I tried all the possible solutions and now I am really tired after one week. Here are the details about my problem Operating System: Red Hat Linux ES 5.0 OpenLDAP Release: 2.3.39 During the addition of userPassword node I get the following error. ldapadd -f /root/openldap/openldap-2.3.39/servers/slapd/schema/paswd_policy1.ldif -D "cn=Manager,dc=xyz,dc=com" -w secret -x adding new entry "cn=default,ouname=ppolicy,oname=P_Policy,dc=xyz,dc=com" ldapadd: Invalid syntax (21) additional info: pwdAttribute: value #0 invalid per syntax Then after reading some of the issues related to it, I tried every possible solution. I added overlay path in my slapd.conf and I got the following error. ./slapd -f /root/openldap/openldap-2.3.39/servers/slapd/slapd.conf -d 1 @(#) $OpenLDAP: slapd 2.3.39 (Aug 25 2008 11:38:51) $ root@localhost.localdomain:/root/openldap/openldap-2.3.39/servers/slapd <mailto:root@localhost.localdomain:/root/openldap/openldap-2.3.39/server s/slapd> daemon_init: listen on ldap:/// <ldap:///> daemon_init: 1 listeners to open... ldap_url_parse_ext(ldap:/// <ldap:///> ) daemon: listener initialized ldap:/// <ldap:///> daemon_init: 2 listeners opened slapd init: initiated server. slap_sasl_init: initialized! bdb_back_initialize: initialize BDB backend bdb_back_initialize: Sleepycat Software: Berkeley DB 4.3.29: (September 12, 2006) hdb_back_initialize: initialize HDB backend hdb_back_initialize: Sleepycat Software: Berkeley DB 4.3.29: (September 12, 2006) overlay "ppolicy" not found slapd destroy: freeing system resources. slapd stopped. connections_destroy: nothing to destroy.
