BTW, I don't see the module asking for authorization for every 
object, only when the client asks for something in a new directory.  
(It's a little hard to tell from the debug log if the calls to the 
samba server are made for every object, I need a little more time to 
follow its logic through.  But, on the client side, I am not seeing 
the 401 returned for every object.)
  


How about improving the module by adding some caching mechanism for 
authenticated users?
Moreover it could be nice to control it with PerlSetVar directives 
(ttl and so on)

BTW, has anyone read the documentation in AuthenNTLM.pm?  Here is an 
example on how to only call AuthenNTLM if a precondition is met...

=head2 Example for overriding
                                                                                                                          

The following code shows the a basic example for creating a module which
overrides the map_user method and calls AuthenNTLM's handler only if a
precondition is met. Note: The functions preconditon_met and lookup_user
do the real work and are not shown here.
                                                                                                                          

                                                                                                                          

   package Apache::MyAuthenNTLM ;
                                                                                                                          

   use Apache::AuthenNTLM ;
                                                                                                                          

   @ISA = ('Apache::AuthenNTLM') ;
                                                                                                                          

                                                                                                                          

   sub handler ($$)
       {
       my ($self, $r) = @_ ;
                                                                                                                          

       return Apache::AuthenNTLM::handler ($self, $r) if 
(precondition_met()) ;
       return DECLINED ;
       }
                                                                                                                          

   sub map_user
                                                                                                                          

       {
       my ($self, $r) = @_ ;
                                                                                                                          

       return lookup_user ($self->{userdomain}, $self->{username}) ;
       }
This should work for now, and I will bang around and see how much work 
it will take to add in a caching feature directly into the module.  
Seems that it would be useful for a lot of people, right?

OK, final questions for the day...

1. Apache-AuthenNTLM already caches the connections to the samba 
server.  I am assuming that we are having a problem with queries passing 
through this connection, and not a "too many connections" problem on the 
samba server end, right?

(NOTE: (Mathias) Apache-AuthenSMB does  not cache the connections, so 
what are we seeing with it exactly? )

2.  Do we really need to handle caching within this module?  Might it 
not be handled by one of the Caching modules that Michael Parker 
mentioned in an earlier email?  
(http://marc.theaimsgroup.com/?l=apache-modperl&m=106780304521226&w=2)

3.  If we do add caching into the Apache-AuthenNTLM mod, where do we 
cache the yes/no variable, and when do we destroy it?

thanks for your input,
