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

[C. Alex. North-Keys]

Just upgraded to Wily here as well and I'm running into the failing
autofs too.  Moving from ldap client to sssd is more dramatic than
desired here - how soon will the 1ubuntu3 be available in the Ubuntu
Wily repos?   As of the time of this post, only 5.1.1-1ubuntu2 is
showing in the Wily repo.

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

Status in autofs package in Ubuntu:
  Fix Released
Status in autofs source package in Wily:
  New

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.
