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

[Malcolm Scott]

This is a regression due to recent (upstream?) refactoring of the
lookup_ldap module's lookup_init function (modules/lookup_ldap.c).

Nothing has initialised the config cache in lib/defaults.c before the
call to defaults_get_ldap_timeout on line 1668.

Previously, this module's first call to defaults.c was
defaults_get_searchdns(); that calls defaults_read_config to initialise
the config cache, whereas defaults_get_ldap_timeout doesn't do this.

Patch attached.

Possibly, for completeness, more functions in defaults.c (e.g.
defaults_get_ldap_network_timeout) should check that the config cache is
initialised before reading from it (at the risk of opening the config
file repeatedly).
