Secure replication
by Real, Elizabeth (392K) 06 May '17

06 May '17

Hey guys, I’m running multi-master OpenLDAP (version 2.4.40) servers and need to secure replication. Can you point me to where I can find that information? What I found online is old and does not apply to the version I’m running. The olcSyncRepl directive on both systems needs to go from: olcSyncRepl: rid=001 provider=ldap to: olcSyncRepl: rid=001 provider=ldaps Thank you, Liz

Fix your cgp.schema to not include the definition for displayName, since that already comes from inetorgperson.schema. And remove any other attributes it is incorrectly defining that are provided from other schema as well. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

The test.conf that you are converting has *zero* knowledge of what you have loaded into cn=config. Generally what one does is, define a test.conf that includes all the necessary schema to convert the additional schema you are converting, and then you do something like: mkdir -p /tmp/test-config slaptest -F /tmp/test-config -f test.conf Then you can use the converted schema that is written into /tmp/test-config. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

You should absolutely not be including elements from other schema into the file simply for the purpose of conversion, as you will end up with a file you won't be able to import to cn=config if it has those other schema included. And, if it had all the elements as you claim, then you certainly wouldn't be getting an error about the "organization" objectClass being missing, given that that comes from the "core" schema file. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Your test LDIF file for converting schema must include all other schema that it is dependent upon for it to be able to convert properly. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Issue importing CGP schema into LDAP (centos 7)
by John Cooter 02 May '17

02 May '17

I have been tasked with virtualizing our existing, aging, LDAP and CommuniGate Pro instances. Doing so will require moving from RHEL 5.X to CentOS 7.X, which means that the existing LDAP implementation has changed. Upon attempting to perform a "slaptest -f test.conf -F testing" where test.conf contains only an include statement that points to /etc/openldap/schema/cgp.schema, and testing is an empty directory, I receive the following error message: 59033edc /etc/openldap/schema/cgp.schema: line 640 objectClass: ObjectClass not found: "organization" slaptest: bad configuration directory! I am able to verify that the various base includes in my LDAP server do include an objectClass "organization" and can verify same in phpLDAPadmin, and in other methods. I am new to the concepts presented here, and since we are using LDAP in what appears to me to be a non-standard use case, I am at a loss. I present the relevant "line 640" below, from the schema I am attempting to import: objectClass ( 2.5.1000.0 NAME 'CommuniGateDomain' SUP 'organization' STRUCTURAL MAY ( cn $ dc ) ) Can someone perhaps tell me where I am going wrong, or how to more effectively troubleshoot this import?
