[Bug 1503034] Re: Autofs 5.1.1-1ubuntu2 crashes with segfault on startup

[Adam Pocock]

I've been running the autofs-ldap & autofs binaries from 14.04 in 15.10,
they work fine.

I had different issues with the 14.10 and 15.04 binaries (on their
respective releases), which never worked with LDAP, but appeared to hard
lock rather than segfault so it was harder to track down.

Title:
  Autofs 5.1.1-1ubuntu2 crashes with segfault on startup

Status in autofs package in Ubuntu:
  Confirmed

Bug description:
  I'm running Wily Beta 2, updated to the latest packages in the wily
  repository, with autofs-ldap using mounts stored in LDAP. On startup
  systemd immediately puts autofs into a failed state as it segfaults
  when reading the auto.master.

  Autofs & autofs-ldap version is 5.1.1-1ubuntu2.

  The log in journalctl looks like this:

  Oct 05 15:47:45 <hostname> autofs[2232]: * Starting automount...

  Oct 05 15:47:47 <hostname> systemd[1]: autofs.service: Control process exited, code=exited status=1

  This occurs whenever the service is started with the line in
  auto.master which loads the ldap mounts. The line which causes the
  issue is
  "+ldap:automountMapName=auto.master.linux,ou=automount,ou=<location>,ou=<group>,o=<group>,dc=<base>,dc=com",
  and this configuration worked on 14.04, 14.10 and 15.04.
