I am convinced now it's a bug, that Net::LDAP::Filter's regexes are inadvertently matching things in the binary data causing the ->new() call to fail and return undef, but I found a work-around. When I looked up the objectGUID reference at LDAPWiki the proper way to create the search term for LDAP is (objectGUID=\12\34\56\78\9a\bc\de\f1) as a kind of escaped byte code.

When I hand-constructed a searchfilter from a 'broken' objectGUID, the search worked

So I wrote the following bit of code to turn the binary objectGUID into a hex string matching that format and I now can properly get all the info for the extant accounts.

sub enc_hex {
        my @h = split(//,unpack('H*',(shift));
        my ($i, $out, $first);
        foreach $i(@h) {if (!$first){$out.="\\$i"; $first=1;} else {$o
+ut.=$i;$first='';}}
        return $out;
        }

Plugging that into my actual module that gets a sAMAccountName from a stored uuencoded objectGUID worked.

There is probably some Perl Master way to write this as a one-liner, but I'll be able to look at this three years from now and understand what I'm doing, so it'll do!

Thanks again for the help!
