Thanks for the quick reply!
I agree the use of spaces in usernames is for most applications bizarre,
but there are several message board systems such as phpBB that DO allow
spaces and several other unusual characters in usernames.

A bit more background: I am using the AuthUser-Database recipe along with
AuthUser to authenticate against the MySQL database of a phpBB message
board. Authentication is working perfectly, except for the problem
building the $auth array from the @group: lines in my Site.AuthUser.
I am willing to live with a non-standard version of the authuser.php
script (mine already is due to a one line change needed for
AuthUser-Database), but need help setting up the expressions for parsing
my Site.AuthUser page. Your suggested format for a @group: line is
exactly what I would like to use, if a workable solution can be found
for the parsing problem.
