Eek, 5 days?!? Sorry about that. Let's see what we can figure out.
First, I've set up a duplicate of your configuration at
http://www.pmwiki.org/sandbox/authtest/ . You can
view the configuration files I'm using at
In setting up the test I found that 2.1.beta2 has a bug dealing
with the "id:*" specification. Now fixed in 2.1.beta3 (just released),
and the bug didn't exist in 2.1.beta1 or earlier versions, so that
can't really explain all of the problems you're having.
As far as I can tell, everything is working on the authtest
site as I would expect it to. Feel free to test it liberally
and let me know anything that seems odd. But lacking that,
I'm guessing it must be a server setting that is causing the problem.

The fact that it's inconsistent makes me wonder if it's a PHP
sessions problem -- almost as if the sessions are immediately being
expired or timed out. I know this problem existed on sourceforge;
somewhere on sf there were one or more PHP scripts running that
had the session expiration set to just a few seconds, and since
by default PHP shares the session files among all scripts, this
had the side effect of causing any entered passwords to be forgotten
almost immediately and re-prompting. The solution on sourceforge
was for each PmWiki installations to create its own session
directory instead of sharing the systemwide default.

However, the fact that you're having trouble on the localhost
would seem to indicate that it's not a shared-installation problem.

Is there a url where we could play with this on one of your servers?
Or, alternatively, could you run a ?action=phpinfo on one of your
installations and compare the "session" settings with the ones that
appear at http://www.pmichaud.com/sandbox/authtest/pmwiki.php?action=phpinfo ?
We'll definitely figure this one out somehow.
