[John James Jacoby]

Here is what worked for me, on my WPMU sub-domain setup. (Sam, when you go through this, I understand that bbPress stores the salts in the DB and that they aren’t needed here, but for some reason I just feel better inside knowing I put them there the same as they are in wp-config.php )

2:05pm eastern time – UPDATE: I have confirmed these settings work on both WPMU subdomain and subdirectory installs. All logins/logouts, cookie clears, posting, and admin panel access works 100%.

WordPress MU is installed on the domain root, bbPress is installed in a SUB-DIRECTORY called “support”

Terms

SUB-DIRECTORY = Name of directory that bbPress is installed in

HASH-FROM-FIREFOX = Cookie hash taken from pre-integrated login cookie

GENERATED = String generated by WordPress key/salt generator
