Lucid's debdiff

** Description changed:

+ == SRU Justification ==
+ 
+ * Impact: users being defined on remote user databases such as LDAP will
+ not be able to access to their cron jobs and these will be marked as
+ orphaned unless cron is restarted. The impact is severe for users
+ relying on cron and using LDAP.
+ 
+ * Fix:
+   The fix was implemented in Fedora's cronie. It implements a list orphan 
which allows to describe jobs as being orphaned or not depending on whether the 
owner is found or not.
+ 
+ * Test case: 
+   How to reproduce:
+      1. Setup an LDAP remote directory and add a user to test.
+      2. Create a crontab for this user with some jobs.
+      3. When a reboot happens, this user will have its jobs orphaned.
+   Expected results:
+      - the cron table is read and jobs are to be executed when required.
+   Actual results:
+      - the cron table / jobs are marked as orphaned.
+ 
+ * Regression potential: very minimal, the fix only adds a list adding a
+ new description to the jobs, these are described as orphans and are
+ checked when necessary.
+ 
+ * Original bug description:
+ 
  We had a server which was happily running Hoary. It authenticated to our 
AD2003
  domain using winbind, and winbind was in the nsswitch.conf. However, after
  upgrading to Breezy, cron no longer works properly, in that it doesn't respect
  accounts from winbind as being valid accounts. My logs are filling up with
  messages like:
  
  Dec 22 09:52:01 thorin /usr/sbin/cron[28207]: (user1) ORPHAN (no passwd entry)
  Dec 22 09:52:01 thorin /usr/sbin/cron[28207]: (user2) ORPHAN (no passwd entry)
  Dec 22 09:55:01 thorin /usr/sbin/cron[28207]: (user3) ORPHAN (no passwd entry)
  Dec 22 09:55:01 thorin /usr/sbin/cron[28207]: (user4) ORPHAN (no passwd entry)
  
  If you do "id user1", their information shows up perfectly fine, so it seems
  like cron has been changed to not respect this source of information.
