strange problem

[Cunningham, C. <ccu...@ma...>]

Hi,

I have a script using perl-ldap to keep an ldap database in sync with a 
password file. It's worked fine for quite some time, however after a 
recent server upgrade (and move from redhat 7.3 to redhat 8.0) it no 
longer works.

When I run it, I get an error that says Broken Pipe. No idea what that 
means, but I'm starting from the beginning in trying to debug it. It is 
trying to add a user to the ldap database that already exists, and that 
obviously won't work. I've tracked it down to this piece of code and put 
in some debugging output:

        if ($search eq "uid=khimgio") { print "same"; }
        chop($search);
        my $result = $ldap->search (
                #base    => $base,
                #scope   => "sub",
                #filter  => "uid=khimgio",
                #attrs   =>  $attrs
                base    => $base,
                scope   => "sub",
                filter  => $search,
                attrs   => $attrs
        );
        if ($result->entries) { print "got it"; }

This is part of a much larger script. When I run it, the first user to be 
processed is khimgio. The script outputs "same" indicating that we are 
using a filter for uid=khimgio. Now here's the interesting part. If I run 
this with the first set of arguments to the search (i.e. with a string 
saying to filter on uid=khimgio), it prints out got it, indicating it 
found the record. If I use the second set of arguments (the ones not 
commented out) which are *exactly* the same only using $search instead of 
manually setting the filter, it does not print out got it.

As far as I can tell, $search is the same as "uid=khimgio". Why would one 
fail and the other work?
