dhcp.schema attribute dhcpStatements value in filter

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, I configured my isc-dhcpd servers to work with openldap, all works now when I want to find dn for some definite MAC or IP, I am unable to do that please, help to understand how can I ldapsearch by attribute dhcpStatements values? in dhcp.schema it is written: - ---[ quotation start ]------------------------------------------- ... attributetype ( 2.16.840.1.113719.1.203.4.3 NAME 'dhcpStatements' EQUALITY caseIgnoreIA5Match DESC 'Flexible storage for specific data depending on what object this exists in.

Then you make a mistake :-( $ ldapsearch -xLLL -H ldap://10.100.0.1 '(&(objectclass=dhcphost) (dhcpStatements=fixed-address 10.100.0.102))' dn dhcpStatements dn: cn=DEBIAN,ou=hosts,cn=DHCP Config,dc=europa,dc=xx dhcpStatements: fixed-address 10.100.0.102 > it is the same picture for anything except dhcpStatements=* ... > > so, how is it correct to write the filter to get all objects with IP > like 10.0.0.2* ? By default, that's not possible. You need to modify the schema to make this work. step 1: find the dhcp schema # ldapsearch -LLLY external -H ldapi:/// -b cn=schema,cn=config dn|grep dhcp dn: cn={7}dhcp,cn=schema,cn=config step2: prepare a ldapmodify input file # echo 'dn: cn={7}dhcp,cn=schema,cn=config' > /tmp/dhcp_s.ldif # echo 'changetype: modify' >> /tmp/dhcp_s.ldif # echo 'replace: olcAttributeTypes' >> /tmp/dhcp_s.ldif step 3: retrieve the attributes from cn=config # ldapsearch -LLLY external -H ldapi:/// -b cn=schema,cn=config 'cn={7}dhcp' olcAttributeTypes >> /tmp/dhcp_s.ldif step 4.1: add Substring match to dhcpStatements with an editor this I have added "SUBSTR caseIgnoreIA5SubstringsMatch" to dhcpStatements. The result is: olcAttributeTypes: {2}( 2.16.840.1.113719.1.203.4.3 NAME 'dhcpStatements' DESC 'Flexible storage for specific data depending on what object this exists in. Like conditional statements, server parameters, etc. This allows the standard to evolve without needing to adjust the schema.' EQUALITY caseIgnoreIA5Match SUBSTR caseIgnoreIA5SubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 ) step 4.2 remove line number 4 in my config 'dn: cn={7}dhcp,cn=schema,cn=config' step 5: update the server # ldapmodify -Y external -H ldapi:/// -f /tmp/dhcp_s.ldif step 6: be happy ;-) $ ldapsearch -xLLL -H ldap://10.100.0.1 '(&(objectclass=dhcphost) (dhcpStatements=fixed-address 10.100.0.*))' dn dhcpStatementsdn: cn=ainf-01,ou=hosts,cn=DHCP Config,dc=europa,dc=xx dhcpStatements: fixed-address 10.100.0.101 dn: cn=ainf-02,ou=hosts,cn=DHCP Config,dc=europa,dc=xx dhcpStatements: fixed-address 10.100.0.103 dhcpStatements: filename "pxelinux.0" dhcpStatements: next-server 10.100.0.1 dhcpStatements: broadcast-address 10.100.255.255 dn: cn=ainf-22,ou=hosts,cn=DHCP Config,dc=europa,dc=xx dhcpStatements: fixed-address 10.100.0.104 dn: cn=DEBIAN,ou=hosts,cn=DHCP Config,dc=europa,dc=xx dhcpStatements: fixed-address 10.100.0.102 hints: 1. modify an objectclass this way, will not work 2. an index on dhcpStatements is not required to make this work perhaps good for performance reasons 3. try it first on a test server :-) -- Harry Jede

I've never configured this kind of architecture, but as far as I know the ppolicy, I think my first thought configuring this would have been to not rebind as user because the attribute modified is an operational one which need the manage right (not sure about that) So I should have configured this with the replication user with manage right and without rebinding as a user when chaining to the master.

openldap for fedora
by Brendan Kearney 30 Mar '14

30 Mar '14

i hope to be getting some new machines and updating/upgrading my ldap instances in the process. i am looking to use the ltb-project.org rpms for the install, but have a couple of questions. first, i do not see any fedora versions in the repo. only redhat 5 and 6. are these packages binary compatible with fedora? second, it seems that the packages use the Sys V Init style, as i am sure the RH servers still use. although that is supported for legacy compatibility in fedora, does the new systemd init style work with these packages? third, is a package for fedora versions available through the ltb-project site? thank you, brendan
