Bug#553188: libnet-ldap-perl: handling of multiple spaces in canonical_dn (Net::LDAP::Util)

[christian mock]

Package: libnet-ldap-perl
Version: 1:0.36-1
Severity: normal

Net::LDAP::Util::canonical_dn fails to compact multiple consecutive
space characters into one. The OpenLDAP server does this compacting,
thus this leads to problems when you compare two DNs.

Reproduce thusly:

use Net::LDAP::Util qw(canonical_dn);

my $dn1 = "cn=tester\\, karl,ou=test,dc=example,dc=com";
my $dn2 = "cn=tester\\,  karl,ou=test,dc=example,dc=com";

print canonical_dn($dn1), "\n";
print canonical_dn($dn2), "\n";

regards,

cm.
