Description

I'm loading schema with code like:

con.loadSchema(new JarLdifSchemaLoader());
con.addSchema("custom.schema");

Later an exception is thrown while I'm handling some search results. The entry in question looks like:

dn: cn=ICRCSSTAccess,ou=Roles,o=jaas,dc=xoint,dc=net
objectClass: groupOfNames
cn: ICRCSSTAccess
member: uid=gturner,ou=people,dc=xoint,dc=net
member: uuid=98bb35ee-9ff3-444f-9925-7fe762810d50,o=Asus,ou=customers,dc=xoint,dc=net

The code where the exception is thrown looks like:

Attribute memberAttribute = entry.get("member");
if (memberAttribute != null)
for (Iterator<Value<?>> iterator = memberAttribute.iterator();
iterator.hasNext()

{ @SuppressWarnings("unchecked") Value<String> value = (Value<String>) iterator.next(); String member = value.getValue(); Dn memberDn = new Dn(context.getSchemaManager(), member); members.add(memberDn); }

It is the Dn instantiation that throws the following stacktrace:

OID 1.3.6.1.4.1.38541.2.1.3 is the uuid attribute that is part of a member DN. "custom.schema" defines it as follows:

attributetype ( 1.3.6.1.4.1.38541.2.1.3
NAME 'uuid'
DESC 'The customer UUID'
EQUALITY UUIDMatch
SYNTAX 1.3.6.1.1.16.1
SINGLE-VALUE )

While scrutinizing the source, looking for why this attribute wouldn't be found in the DefaultSchemaObjectRegistry#byName Map for the AttributeTypeRegistry, I'm beginning to suspect that somewhere around where LdapNetworkConnection#addSchema is calling AttributeTypeRegistry#addMappingFor, it hasn't quite finished the job, perhaps something like calling AttributeTypeRegistry#register (which seems to be the only method that put's into the byName Map).
