# TODO: make sure those dependencies (openssl gnutls nss cyrus-sasl krb5) are
# runtime requirement, I'm (Pierre V.) not sure if the documentation
# http://www.openldap.org/doc/admin24/install.html
# mentioned those dependencies to build OpenLdap or as extra dependency for
# some use case scenario like using tls / kerberos and so on.

# NOTE: You can add openldap-clients for testing purpose
# NOTE: following package are require for building onpenldap:
# openssl gnutls nss cyrus-sasl krb5
