  35 #
  36 # Notes:
  37 #
  38 # 'sssd' performs its own 'files'-based caching, so it should generally
  39 # come before 'files'.
  40 #
  41 # WARNING: Running nscd with a secondary caching service like sssd may
  42 #          lead to unexpected behaviour, especially with how long
  43 #          entries are cached.
  44 #
  45 # Installation instructions:
  46 #
  47 # To use 'db', install the appropriate package(s) (provide 'makedb' and
  48 # libnss_db.so.*), and place the 'db' in front of 'files' for entries
  49 # you want to be looked up first in the databases, like this:
  50 #
  51 # passwd:    db files
  52 # shadow:    db files
  53 # group:     db files
  54
  55 # In alphabetical order. Re-order as required to optimize peformance.
