phpBB3 bridging problem.

[Bertie]

First off I am running locally - so I can't post a link.

The problem is a cookie issue: On pressing login to coppermine I get re-directed to the forum, I login correctly, it redirects me back to the gallery. However I am not logged in.

Coppermine install: Running Locally
Forum install: Running Locally
Coppermine version: 1.4.25 (downloaded today)
Forum version: phpBB3 3.0.4

BridgeManager settings:
Forum URL:  http://localhost/domain/forums/ (Gallery URL is at http://localhost/domain/gallery/)
Relative path to your BBS's config file:  ../forums/
Use post-based groups?:  (tried both no and yes - same issue)
Cookie name/preifx (the phpbb3 cookie name has been used - the default gallery cookie is different)

phpBB3 forums cookie path settings are also set to /

If you don't have anything online we can test you'll need to debug it yourself. Get a firefox extension that shows the HTTP headers being sent and received. Check what cookies the forum is setting, and check what cookies are being sent to Coppermine.
