Hi, I'm having a problem when attempting to expand my directory schema using LDIF. What I'm doing is to place my custom schema into the INSTALLDIR/slapd-INSTANCE/config/schema directory. I stopped the Fedora DS before doing so because base on what I read, the schema should get automatically loaded during the start. I received the following messages when I attempt to start Fedora DS. Starting Fedora Directory Server: [20/Nov/2007:14:47:51 -0500] dse - The entry cn=schema in file /opt/fedora-ds/slapd-<hostname>/config/schema/98_test.ldif is invalid, error code 21 (Invalid syntax) - attribute type testAttribute_1: Missing attribute syntax OID [20/Nov/2007:14:47:52 -0500] dse - Please edit the file to correct the reported problems and then restart the server. [FAILED] Below is my schema dn: cn=schema objectClass: top objectClass: ldapSubentry objectClass: subschema cn: schema attributeTypes: ( testAttribute_1 NAME 'testAttribute_1' DESC 'This is testAttribute_1' EQUALITY caseIgnoreMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 SINGLE-VALUE X-ORIGIN 'user defined' ) attributeTypes: ( testAttribute_1 NAME 'testAttribute_2' DESC 'This is testAttribute_2' EQUALITY caseIgnoreMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 MULTI-VALUE X-ORIGIN 'user defined' ) Is the OID that I defined is invalid? If so what's the best way to generate a OID? or that's something wrong in my LDIF? Regards, - David
