Question about openldap and RFC documents
by Bryan Boone 29 Jun '10

29 Jun '10

Hi everyone, I have a question about openldap and RFC documents. I see online the list of RFC documents that openldap conforms too. RFC documents are difficult to read and follow. I am working on a project that requires me to use. organizationalUnit groupOfNames inetOrgPerson Also I need to use the attributes. uid userpassword I need to document my work so that someone can setup their own LDAP server (maybe non-OpenLDAP) if they wish. I see that RFC2307 referes to the hashing of userpassword. Can anyone list to me the RFC documents that encompass the 3 object classes and the 2 attributes so that I can put that in my documentation? I know I just just list all of the RFC documents on the website for openldap, but I think that is a little redundant. Plus I would like to know exactly which RFC's I am using. thanks

OpenLDAP Issues
by Allgood, John 29 Jun '10

29 Jun '10

Hey All Does anyone know why when I change pam_password exop in /etc/ldap.conf my password history and check_password module that I built into ppolicy stop working. This is openldap 2.4.21 built from source running on Centos 5.5. It worked fine when I had pam_password md5.

Hello I upgraded from 2.4.21 to 2.4.22 from the FreeBSD ports and the slapd daemon does not start anymore ... error message follows /libexec/ld-elf.so.1: /usr/local/libexec/slapd: Undefined symbol "ldap_pvt_csnstr" The configuration is the same and there is no compilation error. Thanks for any infos. F

Can password-hash be database specific? also, storing and verifying cleartext passwords
by Tom Leach 28 Jun '10

28 Jun '10

Is the 'password-hash' configuration function a server-wide setting only or can it be set to different values for separate databases? I'm trying to add MAC-auth RADIUS functionality to my LDAP server (openldap-2.4.21) and I need to store the password for the MAC addresses in cleartext. I also use the LDAP server for user login which I don't want to keep in cleartext. So, my thought was to have 'password-hash {SSHA}' for the users database, and 'password-hash {CLEARTEXT}' for the RADIUS database, but it appears that it's a global so I'm pretty sure this won't work. Also, how do I verify that the passwords are stored in cleartext? On a test server, I've created just the radius database with a global 'password-hash {CLEARTEXT}', I have the following ldif file that I add with: ldapadd -x -W -v -D 'cn=Manager,o=radius' -f mac.ldif -h ldap_server Contents of mac.ldif: dn:uid=001e68d08ff9,o=radius uid: 001e68d08ff9 cn: 001e68d08ff9 userPassword: {cleartext}001e68d08ff9 objectClass: top objectClass: radiusProfile objectClass: radiusObjectProfile but when I use ldapsearch or slapcat to dump the database, the userPassword line looks to be hashed. ldap_server# slapcat dn: o=radius o: radius objectClass: top objectClass: organization structuralObjectClass: organization entryUUID: 97ab4273-42ae-4b41-9100-a8106bf766bf creatorsName: cn=Manager,o=radius createTimestamp: 20100618220235Z entryCSN: 20100618220235.020635Z#000000#000#000000 modifiersName: cn=Manager,o=radius modifyTimestamp: 20100618220235Z dn: uid=001e68d08ff9,o=radius uid: 001e68d08ff9 cn: 001e68d08ff9 userPassword:: e2NsZWFydGV4dH0wMDFlNjhkMDhmZjk= objectClass: top objectClass: radiusprofile objectClass: radiusObjectProfile structuralObjectClass: radiusObjectProfile entryUUID: 591d40f2-a155-4b49-a827-5bfd92ee8c32 creatorsName: cn=Manager,o=radius createTimestamp: 20100619000726Z entryCSN: 20100619000726.747404Z#000000#000#000000 modifiersName: cn=Manager,o=radius modifyTimestamp: 20100619000726Z Here are the relevant lines from the slapd.conf file: include /usr/local/etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/radius.schema password-hash {CLEARTEXT} database bdb suffix "o=radius" rootdn "cn=Manager,o=radius" rootpw "secret" directory /var/lib/ldap/radius index objectClass eq index ou,cn,uid,memberUid eq,pres,sub index uniqueMember eq,pres index entryCSN,entryUUID eq

ldaprc with ldaps:// and ldap:// fallback
by manu＠netbsd.org 27 Jun '10

27 Jun '10

Hello I would like to setup a ldaprc so that an application uses: - a localhost-base slapd without authentification (just relying on filesystem permission on the slapd socket) - if it is not available, a remote slapd, authenticating using client certificate Here is the desired ldaprc: BASE dc=example,dc=net URI ldapi:/// ldaps://ldap.example.net TLS_CACERT /etc/openssl/ca.crt TLS_CERT /etc/openssl/host.crt TLS_KEY /etc/openssl/host.key SASL_MECH EXTERNAL TLS_REQCERT demand Of course it will not work, as the ldapi:/// connection will present a certificate. I have the feeling the setup I am looking for cannot be configured. Is that right? -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz manu(a)netbsd.org
