Create your own schema file, e.g. acp133.schema, with all the attributes and object classes that you need, put it in /usr/local/etc/openldap/schema and add a line to /usr/local/etc/slapd.conf: include /usr/local/etc/openldap/schema/acp133.schema Chris Brook -----Original Message----- From: owner-openldap-software@OpenLDAP.org [mailto:owner-openldap-software@OpenLDAP.org]On Behalf Of Garzon Maldonado, Jesus Javier Sent: Thursday, July 03, 2003 8:35 AM To: openldap-software@OpenLDAP.org Subject: Extending schema Hello all: I'm using OpenLDAP 2.0.35 on FreeBSD 4.7. I wish to include ACP 133 specification wich includes new objects, and attribute definitions together with new name forms, syntax and content rules definitions. However, I don't know how or where attribute syntaxes, content rules and name forms are defined. Does anybody know?. I just know some basic concepts like how to add new objects and attributes. :o( ACP 133 states things like: [...] 4. NAME FORMS 4.1 aCPNetworkEdBNameForm ( 2.16.822.214.171.124.2.4.42 NAME 'aCPNetworkEdBNameForm' OC 2.16.8126.96.36.199.2.3.68 ; aCPNetworkEdB MUST 188.8.131.52 ) ; cn [...] 5. MATCHING RULES 5.1 addressCapabilitiesMatch Matching Rule ( 184.108.40.206.1 NAME 'addressCapabilitiesMatch' SYNTAX 2.16.8220.127.116.11.2.2.16 ) ; Address Capabilities syntax [...] 6. ATTRIBUTE SYNTAXES 6.1 aCPLegacyFormat Attribute Syntax ( 2.16.818.104.22.168.2.2.17 DESC 'aCPLegacyFormat syntax' ) The encoding of a value in this syntax is any one of the INTEGER values: 0 - 15 or 32 - 48 where: 0 means JANAP128, 1 means ACP126, 2 means DOI103, 3 means DOI103Special, [...] 7. EXAMPLE CONTENT RULES The content rules given in ACP 133(B)  are examples, not requirements. The rules included in this document are examples to aid in the specification of similar content rules, especially those derived from these examples. 7.1 aCPApplicationEntityRuleEdA Content Rule ( 22.214.171.124 NAME 'aCPApplicationEntityRuleEdA' ; applicationEntity object class AUX ( 126.96.36.199 $ ; pkiCA 2.16.8188.8.131.52.2.3.66 ) ; securePkiUser MAY ( 2.16.8184.108.40.206.2.1.49 $ ; aliasPointer 220.127.116.11 $ ; dnQualifier 2.16.818.104.22.168.2.1.55 $ ; effectiveDate 2.16.822.214.171.124.2.1.57 ) ) ; expirationDate [...] ..... and I don't know what should I do. Any help will be appreciated. Regards. Javi Garzon.
