perlknight has asked for the wisdom of the Perl Monks concerning the following question:

All, I am doing a search with base name of an object which only has attribute. The count method returns 0, I am calling attributes and dn method, it's bomming out with the following error: 
Can't call method "dn" on an undefined value at ./query_ldap2.pl line 
+83, <DATA> line 283.

} elsif ( $result->count() eq 0 ) {      
    my $entry = $result->entry(0);      
    print        "********",$entry->dn(),"*********\n";               
+      
    #my @pattrs =  $entry->attributes;      
    #print "******** @pattrs **********\n";
} else {

Any idea as to why? Thanks.

    There are no entries (count = 0), so why would you expect to get an entry from entry()?

    By the way, use == (not eq) for numerical comparisons.

    } elsif ( $result->count() eq '0' ) {      
    my $entry = $result->entry(0);      
    if ( $entry ) {
      print        "********",$entry->dn(),"*********\n";             
+        
    } else {
        # blah blah blah
    }
    #my @pattrs =  $entry->attributes;      
    #print "******** @pattrs **********\n";
