# Note about OpenLDAP:
# The openldap-client package is part of Slackware since the 11.0 release.
# If you want to store your KDC database in LDAP, you will need to configure
# Heimdal with support for OpenLDAP:
# Replace this:  "--without-openldap"  with this:  "--with-openldap=/usr"
# in the configure lines below
