[Grok-dev] Grok, sessions and authentication

Hello grokkers,

I'm currently working on an users/groups system inside Dolmen and i'm
fighting with the authentication and publishing process, to be able to
allow certain URL to bypass the authentication.
This is, obviously, for public resources retrieving.

Digging into the zope-dev mail logs, I also found reports of problems
i'm experiencing in Dolmen, involving read-write errors while
accessing ZODB blobs.

I get logs like :
2010-06-09 13:39:27,209 WARNING [ZopePublication] Competing
writes/reads at SOMEURL: database conflict error (oid 0xfa, class
dolmen.storage.container.OOBTreeStorage, serial this txn started with
0x0386b65fab734455 2010-06-09 10:39:40.183655, serial currently
committed 0x0386b69b740d2a88 2010-06-09 11:39:27.199554)

It seems it's linked to sessions. So, i'm launching a general buoy for
the guys out there that have experience with zope3 and auth (Martijn,
J-W ?). Can you give me some tips in these matters ?
