PerlAuthenHandler - Allowing necessary URLs to pass thru or be excluded

[Andy Hale]

I have a custom PerlAuthenHandler that works fine when protecting 
particular URLs but if I try to protect the document root it also 
protects necessary URLs I use for login and logout.  Is there a way that 
I can exclude particular URLs or allow them to pass thru? 

Here is my SSO.conf file
-----CUT-----
#<IfModule mod_perl.c>
PerlOptions +GlobalRequest
<Location /SSO-login>
  SetHandler perl-script
  PerlHandler SSO::SSOAuthHandler->login
  AuthType SSO::SSOAuthHandler
  AuthName SSO
</Location>
<Location /SSO-logout>
  SetHandler perl-script
  PerlHandler SSO::SSOAuthHandler->logout
  AuthType SSO::SSOAuthHandler
  AuthName SSO
</Location>
# Below are URI locations to be protected
# Protect /manual
<Location /manual>
 PerlAuthenHandler SSO::SSOAuthHandler->authenticate
 AuthType SSO::SSOAuthHandler
 AuthName SSO
 require valid-user
</Location>
# Protect /
<Location />
 PerlAuthenHandler SSO::SSOAuthHandler->authenticate
 AuthType SSO::SSOAuthHandler
 AuthName SSO
 require valid-user
</Location>
#</IfModule>
