--domain Query maps for a non-default domain (default is
"$domain").
--server Query a non-default server (default is
"$server").
--suffix Store entries under a non-default suffix (default is
"$suffix").
--people Store account entries under a non-default container
under the suffix (default is "$people").
--groups Store group entries under a non-default container
under the suffix (default is "$groups").
--nomergegroups Don't merge group entries which have the same GID.
--rfc2307bis Use groupOfNames groups, create user account
entries which are also inetOrgPerson entries.
--ipa Use groupOfNames groups, create user account
entries which are also inetOrgPerson and Kerberos
user entries.
--realm Use a non-default Kerberos realm name (default is
"$realm").
--email Add email addresses by default (default domain for
mail addresses is "$domain").
-a --all Attempt to migrate all maps in the local domain.
(Can not be used with either the --server or
the --domain options.)
--containers Create containers for maps in addition to entries.
--just-containers Create containers for maps, but not for entries.
