Subject Issue with entryCSN attribute and schema...
Date Sun, 31 May 2009 11:57:33 GMT
Hi guys,

as I'm trying to inject some operationalAttributes in every entries, I 
face an interesting problem. Obviously, the schema elements must also 
have an entryUUID and entryCSN attributes. For entryUUID, there is no 
problem, so far, but for entryCSN, that's not the same story... As this 
AT is built based on the local instance (the SID is part of the CSN), we 
can't anymore use the pre-built schema partition, as it's totally 
instance agnostic.

We have options though :
- defining a special sid for such entries, 0xFFF for instance. It's very 
unlikely that we will see any day such a number used for CSN.
- get rid of this pre-built partition. We load the schema dynamically on 
server startup, and inject CSN at startup
- modify the entryCSN for those entries at startup, to inject the 
current SID

At least, these are the options I'm considering right now. I don't think 
we have time to implement (2) atm, so my guts tell me that option (1) is 
probably the best for the moment.

thoughts ?

cordialement, regards,
Emmanuel L├ęcharny
