ACL LISTRIGHTS

[Timo Sirainen <tss@xxxxxx>]

Now that I'm beginning to implement ACLs for my server, I finally got
around to reading rfc4314 (unfortunately I didn't really have time while
it was still in draft).

I noticed one bug in it:

   Example:    C: a005 listrights archive/imap anyone
               S: * LISTRIGHTS archive.imap anyone ""

But what I'm wondering is what does the "required rights" parameter mean
in LISTRIGHTS reply? Is it the same as what rights the user currently
has (ie. for "LISTRIGHTS INBOX <myusername>" it's the same as "MYRIGHTS
INBOX"?

Also it looks like the "optional rights" doesn't necessarily list all
the possible rights that the RFC defines. Is there a reason why server
wouldn't list all of them? Except possibly if it doesn't support the
feature at all?
