# put in /etc/krb5.conf and the ACLs on the objects are set up appropriately.
#
# Examples:
#
# # Create primary keytab file (default is primary)
# base::wallet { "service/adroit-gerbil":
# path => "/etc/adroit/gerbil.keytab",
# owner => "leroy",
# primary => true,
# ensure => present,
# }
#
# # Add another keytab to the above primary keytab
# base::wallet { "service/adroit-gerbil-another":
# path => "/etc/adroit/gerbil.keytab",
# primary => false,
# require => Base::Wallet["service/adroit-gerbil"],
# ensure => present,
# }
#
# # Remove the keytab file
# base::wallet { "service/funky-chicken":
# path => "/etc/funky/chicken.keytab",
# ensure => absent,
# }
#
# # Download a password file.
# base::wallet { "unix-foobar-db-baz":
# path => "/etc/foobar/password",
# type => "file",
# }
# These helper routines are broken out separately to reduce indentation, but
# shouldn't be called separately. They're purely an implementation detail.
