Write a test script using Authen::Smb and run it from the commandline.
You can copy-paste the synopsis portion of the Authen::Smb documentation
(i.e. perldoc Authen::Smb). 

If (you can connect and and authenticate from the commandline) { 
   the problem resides in your mod_perl installation, 
   # either an @INC problem, or re-install mod_perl.
}
else {
   problem with your Perl installation
   # re-install Perl
}
