PhpBB2.0.2.1 to coppermine bridge - not quite there

[Ripla]

I have the following issue when trying to bridge coppermine and PhpBB2.0.2.1:

I have done all the bridging and it all seems to work apart from once trying to login via coppermine it correctly takes me to the BB login page.  It logs me in and then takes me back to the coppermine home page, however I am not logged in.

If i go back to the BB i am logged in.  I have a feeling it is something to do with the cookie settings in either the BB or the bridged Coppermine, but I am no expert and dare not go changing things.

Coppermine install: http://www.rallycrossuk.com/coppermine/
Forum install: http://www.rallycrossuk.com/brda_forum
Coppermine version: cpg1.4.10
Forum version: PhpBB 2.0.2.1
Test user account: test  -  the password test

BridgeManager settings:
Forum URL:  http://www.rallycrossuk.com/brda_forum
Relative path to your BBS's config file:  ../brda_forum/
Use post-based groups?:  0
Cookie name     rallycross_forum

Hope someone can sort it out for me

Thanks in advance
