Yes, but that results in combinations of software that are not redistributable in the archive because there's GPL software that uses libldap. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.

Lucid Release Note: == NSS via LDAP+SSL breaks setuid applications like sudo == Upgrading systems configured to use ldap over ssl as the first service in the nss stack (in nsswitch.conf) leads to a broken nss resolution for setuid applications after the upgrade to Lucid (for example sudo would stop working). There isn't any simple workaround for now. One option is to switch to libnss-ldapd in place of libnss-ldap before the upgrade. Another one consists in using nscd before the upgrade. -- Mailing list: https://launchpad.net/~tieto Post to : [email protected] Unsubscribe : https://launchpad.net/~tieto More help : https://help.launchpad.net/ListHelp
