[Zope-CMF] Login troubles.

[John Morton]

I've just moved a portal site from one server to another, upgrading from 
python2.1.1 -> 2.1.2 on both servers in the process. Both are using the 
same set of products (CMF-1.2 + Decor, Collector and Wiki from the same CVS 
snapshot). Both are serving up requests via an apache proxy pass 
configuration.

On the original server, I can log into the site without a problem. On the new 
server with the copied site, I can, as it never sends an '__ac' cookie. It 
does set other cookies (ie 'tree-s', '__ac_name') and it does let me log in 
as the admin user via Basic Auth. 

Anyone know where I should start looking to solve this problem?

Thanks,
John
