I am trying to query the definition of an attribute type using one of the attribute type's aliases. For example, given:
attributetype ( 2.5.4.3 NAME ( 'cn' 'commonName' ) DESC 'RFC2256: common name(s) for which the entity is known by' SUP name )
I am using Java's naming API to query the definition, and getting an exception saying the attribute type doesn't exist. Example:
DirContext cnSchema = (DirContext)schema.lookup("AttributeDefinition/commonName");
I appreciate that this is not a Java list - I am trying to determine if what I am seeing is consistent with one of the many LDAP RFC's (i.e. I must use the actual attribute type's name to get the definition). If not I'll peddle my query elsewhere :)
Thanks,
Kevin Hardiman

The LDAP operation to query the schema will return *all* attribute type definitions in one result. Therefore it must be the client-end code that extracts the particular definition that you have asked for.
Attributes with multiple names are an unfortunate feature of LDAP. In X.500 the protocol deals only in OIDs so there can be no ambiguity, but LDAP servers and clients have not always been careful to handle the multiple names as equivalent.
I suggest you dig into the Java code that provides the service to your program.
