resolvconf cause nss_ldap connection failures while booting

Bug #1700472 reported by Tobias Mark
This bug affects 2 people
Affects Status Importance Assigned to Milestone
resolvconf (Ubuntu)

Bug Description

Ubuntu 16.04.2 LTS
resolvconf: 1.78ubuntu4

If the server is configured to use a remote ldap during boot a bunch of this messages appears:

  sh nss_ldap: could not connect to any LDAP server as [..] - Can't contact LDAP server

This appears to be cause by /sbin/resolvconf:

        case "$IFACE" in
          */*) report_iface_err "Slash" ; exit 1 ;;
          *" "*) report_iface_err "Space" ; exit 1 ;;
          .*) report_iface_err "Initial dot" ; exit 1 ;;
          -*) report_iface_err "Initial hyphen" ; exit 1 ;;
          ~*) report_iface_err "Initial tilde" ; exit 1 ;;

Proposed patch:
- ~*) report_iface_err "Initial tilde" ; exit 1 ;;
+ "~"*) report_iface_err "Initial tilde" ; exit 1 ;;

The shell will try to expand ~* to the home directory of user '*'. This is probably not intended and cause the error because during ifup the ldap can't be reached.
