No responses, but I found a solution. I still don't know why I can't turn around and use the same retrieved data for the filter criteria 100% of the time, but using information from the following:

GUIDs and SIDs

Net::LDAP GUID...

I can now search by the objectGUID 100% of the time in my tests. 

sub GuidToString { 
    my $stringGUID = unpack("H*", shift); 
    $stringGUID =~ s/^(\w\w)(\w\w)(\w\w)(\w\w)(\w\w)(\w\w)(\w\w)(\w\w)
+(\w\w)(\w\w)(\w\w)(\w\w)(\w\w)(\w\w)(\w\w)(\w\w)/\\$1\\$2\\$3\\$4\\$5
+\\$6\\$7\\$8\\$9\\$10\\$11\\$12\\$13\\$14\\$15\\$16/; 
    return $stringGUID; 
}
