When I examine my slapcat of the config database (multi-master
replication), I see a duplicate contextCSN; one of them seems obsolete:
contextCSN: 20130722065709.189194Z#000000#000#000000
contextCSN: 20130729112421.079210Z#000000#001#000000

Can I remove one of those, and if so, how? I tried once, but the CSN
re-appered, maybe from an other master...

Or are those expected to be there?

The #000# CSN if from when the database was single master. It will never update once you've moved to MMR, but there are likely still entries that existed prior to MMR with entryCSNs with #000#. You can simply ignore that CSN now that you are in MMR mode. The script I wrote to compare CSNs across MMR nodes does exactly that (ignore's the #000# CSN).
