Subclassing Apache::AuthDBI

I'm trying to subclass Apache::AuthDBI by doing:

package MyAuthDBI;

use base "Apache::AuthDBI";
1;


Then in apache.conf

PerlModule MyAuthDBI

AuthType Basic
PerlAuthenHandler MyAuthDBI::authen
....


I'm getting the following error:

....failed to resolve handler `MyAuthDBI::authen': Can't locate
MyAuthDBI/authen.pm in @INC...

Which kinda makes sense as an error message since the handler is
declared MyAuthDBI::authen and not MyAuthDBI->authen and yet it works
just fine if I allow Apache::AuthDBI to handle the Authen.

Is it non trivial to subclass Apache::AuthDBI? Am I doing something
glaringly dumb?

Thanks again...

Re: Subclassing Apache::AuthDBI

I'm enjoying talking to myself here all month! So the solution to my
problem below...

Yay to MidLifeXis on PerlMonks for pointing out the problem.

When MyAuthDBI::authen is called then PERL looks to that specific object
for the function rather than traversing up the parent tree.
MyAuthDBI->authen would call the function but the original
Apache::AuthDBI::authen expects $r as the first argument and not $self
and so a new set of problems arises.

So the easy solution to this problem is:

package MyAuthDBI;
use base "Apache::AuthDBI";
sub authen {
my ($r) = @_;
Apache::AuthDBI::authen($r);
}
1;

To answer my final question, yes I was doing something glaringly dumb :)
