# $distribution: A valid Debian distribution. This can
#   be the usual ones, such as "jessie", "stretch", "buster", "sid".

#   "stretch-acs-dev", "stretch-acs-prod", etc.

# IMPORTANT! This class assumes that the APT sources list file is already
# present

#  #########
#  Example 1
#
#  class {'su_ldap::openldap_install':
#    distribution => 'stretch'
#  }
#
#  This will install the stock OpenLDAP packages from the stretch distribution.
#
#
#  #########
#  Example 2:
#
#  class {'su_ldap::openldap_install':
#    distribution => 'stretch-acs-dev'
#  }
#
# This will install the OpenLDAP packages from the special stretch-acs-dev
# distribution that resides in the "stanford" repository.
