### BEGIN INIT INFO
# Provides:          opendj
# Required-Start:
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: This is the opendj daemon
# Description:       OpenDJ is an LDAPv3 compliant directory service, developed for the Java
#                    platform, providing a high performance, highly available and secure store
#                    for the identities managed by enterprises. Its easy installation process,
#                    combined with the power of the Java platform makes OpenDJ one of the
#                    simplest and fastest directory servers to deploy and manage.
