cn=config and authz-regexp
by Julien Vehent 30 Nov '10

30 Nov '10

Hi list, I'm moving a LDAP directory on a freshly installed Debian Squeeze and I'm discovering cn=config. On my former installation, I have SASL configured using : --- authz-regexp "^uid=([^,]+).*,cn=[^,]*,cn=auth$" "ldap:///dc=domain,dc=net??sub?(uid=$1)" authz-policy to password-hash {CLEARTEXT} --- How do I translate this into cn=config directives ? I believe it should be stored into /etc/ldap/slapd.d/cn=config/olcDatabase\=\{1\}hdb.ldif is that correct ? Thanks, Julien

RE: Problems Enabling Authentication using Cyrus SASL
by Fernando Torrez 29 Nov '10

29 Nov '10

Hi all I got work sasl authentication to access ldap server by correcting two things: 1.- inserting the proxyuser's userpassword in clear text (userPassord=secret) 2.- fixing the proxyuser's authzTo atributte to authzTo: ldap:///ou=people,dc=plainjoe,dc=org??sub?(objectClass=account) (results at the end of this mail) As far as it can be seen, there's no need for cyrus-sasl for these matter but my final purpose is to enable Cyrus-sasl with openldap as backend to authenticate users for cyrus-imapd and postfix services. Any hints would be appreciated. Thanks to all for your support Fernando firewall:~ # ldapwhoami -U proxyuser -X u:test -Y digest-md5 SASL/DIGEST-MD5 authentication started Please enter your password: SASL username: u:test SASL SSF: 128 SASL data security layer installed. dn:uid=test,ou=people,dc=plainjoe,dc=org firewall:~ # ldapsearch -Y digest-md5 -U proxyuser -b 'dc=plainjoe,dc=org' '(objectclass=*)' SASL/DIGEST-MD5 authentication started Please enter your password: SASL username: proxyuser SASL SSF: 128 SASL data security layer installed. # extended LDIF # # LDAPv3 # base <dc=plainjoe,dc=org> with scope subtree # filter: (objectclass=*)

Using shell database
by krishan kumar 29 Nov '10

29 Nov '10

Hello, I have compiled openldap-2.4.23 from source. Recently I am learning to use shell database so I try running searchexample.sh script file provided with the openldap sources. But I am not successful in doing so. I think script is not getting executed and I am not getting any search results.

OpenLDAP runs OK, Mac Mail and Address book do not display entries.
by Toomas Vendelin 29 Nov '10

29 Nov '10

Hi, I have set up an OpenLDAP server on a CentOS 5.5 machine and uploaded test data from ldif file. Apache directory studio connects to server nicely from my Mac and displays the records. Apple Mail and address book also seem to connect OK, but no search results returned in Address Book, and e-mails are not auto-completed in Mail. At the same time, I successfully connect to other publicly accessible servers, so it is probably a fault in my LDIF data. What is it? Do I need to use some schema specific to Apple? As for now, only the default ones are used. My LDIF data (all characters are fictional): Code: dn: dc=minu,dc=biz dc: minu objectClass: dcObject objectClass: organization o: Vendelin & Barilko dn: ou=people,dc=minu,dc=biz ou: people objectClass: organizationalUnit dn: cn=Deniska Borilko, ou=people,dc=minu,dc=biz cn: Deniska Borilko objectClass: inetOrgPerson sn: Borilko mail: denis(a)somedomain.com My LDAP settings both in Mail and address book: Code: Search base: ou=people,dc=minu,dc=biz Scope: subtree Thanks in advance!

Content-Based Access Control?
by Frank Rust 29 Nov '10

29 Nov '10

Hi all, would it be possible to configure a content-based access control? I have following configuration: my ldap contains user data. Some of the users are local ones and have a regular password entry. They shall be able to change their password. Other users are remotely authenticated with saslauthd. They shall not be able to change their 'password' which is just a redirection. Example: dn: uid=remoteuser,ou=People,dc=mydomain,dc=de uid: remoteuser cn: Adam Example uidNumber: 9007 gidNumber: 90 sn: Example userPassword: {SASL}remoteuser dn: uid=localuser,ou=People,dc=mydomain,dc=de uid: localuser cn: Bruce Somename uidNumber: 1001 gidNumber: 10 sn: Somename userPassword: {SHA}03de6c570bfe24bfc328ccd7ca46b76eadaf4334 User localuser shall be able to change his password, user remoteuser not. Can this be done by a fancy ACL entry, rejecting to change passwords starting with '{SASL}' ? Thanks in advance, Frank

Problem when trying to authenticate squid with openldap server
by Bruno Lamps 26 Nov '10

26 Nov '10

Hi everybody, I spent some days reading the ebook "Ldap for rocket scientists" ( zytrax.com/books/ldap/) and I've succesfully (I think it's a success =3 ) created a VM with debian lenny and openldap running. After that, I created another VM, running IPfire (www.ipfire.org) distro, this will be the firewall of the SMB I'm working for. Now I'm trying to authenticate the squid proxy, installed in IPFire distro, integrating it with my openldap server. A screenshot of my IPFire's webGUI and phpldapadmin webGUI can be seen at this topic: http://forum.ipfire.org/index.php?topic=3404.0 But the authentication isn't running, the browser using squid proxy keeps asking me for username and password. Suspecting that the webGUI could be making some mistake in squid config file, I started editing it's parameters manually. Right now, the ldap authentication line in my squid.conf looks like this: *auth_param basic program /usr/lib/squid/squid_ldap_auth -D "cn=admin,dc=pisolar" -w "mypassword" -b "ou=usuarios,dc=pisolar" -h 192.168.1.7 -v 3* * * *cn=admin,dc=pisolar *= my root user. * * *ou=usuarios,dc=pisolar *= the OU where my users are stored. * * I opened slapd in debug mode (slapd -d 255) in my openldap debian-powered VM, and this is the text shown when I try to authenticate in my browser: daemon: activity on 1 descriptor daemon: activity on: slap_listener_activate(8): daemon: epoll: listen=7

================================= I tried to set a lot of different config syntaxes at squid.conf, but it always come to the same kind of problem at slapd debug: After reading the user CN and his password, slapd fails to read something else (ldap_read: want=8 error=Resource temporarily unavailable) and then it doesn't authenticates. What I'm doing wrong? Is there any problem with my openldap server? With squid? =( I'd like to thank you all in advance for any support, and say sorry for my broken english. =D

Re: How to set Multiple base dn
by Hallvard B Furuseth 26 Nov '10

26 Nov '10

Please keep replies on the list. Then others can help when I'm not around. Laurent gobalraja writes: > In fact i need a complete split of the bases. The reason is that i need > duplication of cn in both domain and that is not possible in a single base > as the CN must be unique. I think you mean "dc" instead of "cn" here, but I don't think that's what you're supposed to mean:-) Maybe you mean the part of the DN below the database suffix must include the fully qualified domain name, like this? Domain here.org in database foo and there.org in database bar: database bdb suffix o=foo database bdb suffix o=bar Object names: o=foo dc=org,o=foo dc=here,dc=org,o=foo o=bar dc=org,o=foo dc=there,dc=org,o=bar or o=foo associatedDomain=here.org,o=foo o=bar associatedDomain=there.org,o=bar 'o' is short for organization name. associatedDomain, unlike dc, is for full domain names. For 'o' you need the organization object class, for associatedDomian you need domainRelatedObject from cosine.schema. Anyway, you don't need to use 'dc' if that does not suit you. Look for attributes and object classes that describe the actual structure of your intended directory tree. Though note that 'ou' (organizational unit) is often abused for "container" objects like "ou=people". >> Or write slapd.conf first according to the Admin Guide and then use >> sbin/slaptest -f <slapd.conf filename> -F <slapd.d directory> >> to convert to cn=config format. > > Is it safe to make successives updates of slapd.conf and then convert to the > slapd.d directory directly without removing it each time ? That's not supposed to work. Maybe you should just stay with slapd.conf instead? Or find some tool to help edit cn=config - there are supposed to be several, but I'm not up to date on that. -- Hallvard
