Agreed. Do you think I should file this as a bug?

Meanwhile, I've been delving a little deeper into this problem, and have
I think figured out why it's not an issue when slurpd processes a replog
created by slapd...

slapd's replog includes a bunch of extra attributes, some of which I 
recognise,
others are new to me:

replica: localhost:9999
time: 1042007086
dn: dc=my-domain,dc=com
changetype: add
objectClass: dcObject
objectClass: organization
dc: my-domain
o: my-domain # <-- This is the last of my attributes
structuralObjectClass: organization
entryUUID: a0a1acca-b71d-1026-87b3-ead925592f3d
creatorsName: cn=Manager,dc=my-domain,dc=com
createTimestamp: 20030108062446Z
entryCSN: 2003010806:24:46Z#0x0001#0#0000
modifiersName: cn=Manager,dc=my-domain,dc=com
modifyTimestamp: 20030108062446Z

The interesting attribute here is structuralObjectClass, as the error 
that
I'm seeing is coming from a function that is attempting to determine the
Structural Object Class... I'm still not 100% on why this is necessary, 
it's
something to do with the internals of slapd, and it's new since I 
understood
most of how slapd worked. I can easily add this attribute to the replog 
I
create, I'm wondering if I should be adding entryCSN and entryUUID? What
are the rules for the values of those attributes? What are they used 
for?

My original plan was to just create a replog with the changes I wanted,
and to let slurpd apply them to the directory for me. I was hoping that
the create and modify name and timestamp attributes would be added by 
the
directory when slapd performed the operations specified (I wasn't going
to specify updatedn on the target directory). Doesn't look like it's 
quite
as simple as I had hoped.

I know, slurpd isn't necessarily intended to be used in the way I'm 
using it,
but it is very convenient as a way of handing off responsibility for 
getting
updates done asynchronously and relatively reliably. I think it would 
be a
good thing if this worked, without requiring the writer of the replog 
to jump
through hoops and know how the internals of slapd work. The man page for
slapd.replog seems to imply that this is something that you should be 
able
to do, but it doesn't mention any of the extra attributes you need to 
include
to make it work.

So, should I file this as a bug? Is it a bug in slurpd or slapd or both?

Alternatively, if I should be adding the magic attributes to my replog,
can anyone tell me how I should construct the values for entry[CSN|UUID]
and what those attributes are actually used for?

Thanks,
Bernard.
