#######################################################################
# Migration from MySQL to LDAP. #
#######################################################################
# This file depends on the LDAP version of Fripost::Schema.
# (git checkout ldap)
#
# It reads LDAP's configuration from `./ldap.yml', and the MySQL
# configuration from `./dbh.yml'. (The MySQL configuration is the old
# configuration (default.yml) that was read by the vanilla fripost-tools
# (from the master branch).
#
# Set the flag `--pretend' to only simulate the migration.
# REMARK: The migration has not been tested yet!
#
# The changes and warnings are dumped both into the standard error, and
# into a log file "fripost-migration-$$.log", where "$$" is the current
# PID.
#
# REMARK: the columns `create_date' and `change_date' are ignored
# (reseted, actually), since the corresponding LDAP attributes are set
# by the server and there is no way for the client to force their value.
#
# Some other columns may be ignored during the migration (e.g.,
# `domain.description' if it does not have the right form), but the
# program is supposed to say so.
#
# REMARK: The columns `alias.domain', and `mailbox.domain' are not in
# the LDAP schema.
