Sorry, I forgot, the recording of ownercase is in 9.11 (required new db method which is why it wasn't back ported). 9.10 still uses the rbt case. This preserves the in zone labels assuming the authoritative server preserves the learnt case. I've been using 9.11.0pre-alpha for too long. This has advantages (I discover bugs in new code first) and disadvantages (you aren't running exactly what everyone else is and occassionaly you forget that a feature isn't yet available). I think the advantages outweigh the disadvantages most of the time. That said anything matching ownernames should be doing this case insensitively.
