Subject [jira] [Updated] (DIRAPI-154) Implement "online" OpenLDAP schema parsing in DefaultSchemaLoader
Date Wed, 21 Aug 2013 23:05:52 GMT


Gerald Turner updated DIRAPI-154:

    Attachment: loadSchema.log


I built the project with the 'if (isApacheDs...' removed and it's now loading the schema from
the OpenLDAP server.

However loadSchema() throws an exception and I see a bunch of log output about duplicates
and other brokeness. there are errors while loading
the schema

> The constructor in DefaultSchemaLoader has the following comment:
>   // TODO Handle schema loading on other LDAP servers
> For OpenLDAP this would require searching subtree under cn=schema,cn=config and handling
attributes like:
>   olcAttributeTypes: {1}( NAME ( 'sn' 'surname' ) DESC 'RFC2256: last (family)
name(s) for which the entity is known by' SUP name )
>   olcObjectClasses: {4}( NAME 'person' DESC 'RFC2256: a person' SUP top STRUCTURAL
MUST ( sn $ cn ) MAY ( userPassword $ telephoneNumber $ seeAlso $ description ) )
> Note that there is also an 'olcObjectIdentifier' attribute type that seems to be used
to create macros for interpolation in OID's used in other attributes:
>   olcObjectIdentifier: OLcfg
>   olcObjectIdentifier: OLcfgAt OLcfg:3
>   olcObjectIdentifier: OLcfgOvAt OLcfgAt:3
>   olcObjectIdentifier: OMsyn
>   olcObjectIdentifier: OMsBoolean OMsyn:7
>   olcAttributeTypes: ( OLcfgOvAt:10.4 NAME 'olcUniqueStrict' DESC 'Enforce uniqueness
of null values' EQUALITY booleanMatch SYNTAX OMsBoolean SINGLE-VALUE )
> However this additional complexity seems to only be used for the internal/vendor-specific
schema itself (not 'core', 'nis', etc.).
> Attached is LDIF output of from searching cn=schema,cn=config.
