[Koha] Authentication problem using 1.2.3RC11

[Roger Buck]

I have just started playing around with 1.2.3RC11
 
I am wodering what I need to configure to avoid this message:

REJECTED 
You do not have access to this portion of Koha

=======================
What I have done:
Vanilla koha install (using install.pl on linux), with all default
values.

I login using kohaadmin and kohapassword.

Apache basic authentication is NOT configured for any koha directories.

When I click on "Members" menu item it takes me to "members-home.pl"
with message:
 
"REJECTED 
 You do not have access to this portion of Koha"

Looking at cookies file, I note that my browser has set 2 cookies: 1
sessionID for each port - 8000 and 8001.

In a previous message from Steve about authentication: 

2.  checkauth() checks for a $ENV{'REMOTE_USERNAME'} environment
variable.

  a.  If one is set, assume that basic authentication of some sort is
being used

  b.  check that this user is allowed to be running this script.  If
not, print a warning page and exit (possibly redirect to library home
page or somesuch?).

  c.  return a zero value and the userid logged in and the script
carries on.
========================

Any ideas what I need to configure?
