How to retrieve/display ModifyTimestamp attribute with embedded server in code?

[david jones]

Using ApacheDS 1.5 as an embedded server.
I Added a new user:
context.createSubcontext(userName, attributes);

and then retrieve it:
Attributes attrs = context.getAttributes(userName);

When looping through attrs i get all the expected info (ObjectClass, sn, cn,
uid, etc),
but i don't see several attributes that DS is adding under the covers (ex.
AccessControlSubentries, modifyTimestamp, entryUUID, etc.)

I do see the additional attributes when looking at the entry with Apache
Directory Studio.
How can I get to them with java code?

Thanks,
David
