I've updated the patch to the release notes (attached) to become a recommendation to switch to nss-pam-ldapd. Note that I don't think this will totally fix the problem with sudo-ldap (haven't checked) because it will still do LDAP searches to retrieve the sudoers information. If those searches go over SSL/TLS the problem will still be triggered. Dear release notes team, should this change be committed to the release notes? Also, do you think it is a good idea to highlight the switch to nss-pam-ldapd a bit more in the "What's new" section? I think it should also be a good idea to switch for people not affected by this specific problem. I can provide a patch if needed. Thanks. -- -- arthur - adejong@debian.org - http://people.debian.org/~adejong --
