PmWiki uses PHP sessions to keep track of authentication/authorization
information, and by default PHP sets things up such that all interactions
with the same server are considered part of the same session.
An easy way to fix this is to make sure each wiki is using a different
cookie name for its session identifier. Near the top of one of
the wiki's local/config.php files, before calling authuser or any
other recipes, add a line like:
You can pick any alphanumeric name for XYZSESSID; for example,
for the cs559-1 wiki you might choose
This will keep the two wikis' sessions independent of each other.

I'm not sure about this one -- does the second wiki have read
permissions to the local password file? Perhaps double-check
the filenames and file paths?

The above should fix this issue.

It's entirely possible, we just need to figure out why the second
wiki's authorizations aren't working.
