+Starting with CloudStack 4.11, an LDAP connection per domain can be
+defined. In this domain autosync per account can be confirgured,
+keeping the users in the domain up to date with their group membership
+in LDAP.
+.. Note:: A caveat with this is that ApacheDS does not yet support the
+virtual 'memberOf' attribute needed to check if a user moved to
+another account. MicrosoftAD and openldap as well as openDJ do support
+this. It is a planned feature for ApacheDS that can be tracked in
+https://issues.apache.org/jira/browse/DIRSERVER-1844.

+There are now three ways to link LDAP users to cloudstack users. These
+three ways where developed as estensions to each other.
+
+#. manual import. A user is explicitely mapped to a daomain/account
+   and created as a user in that account
+
+     To authenticate, username and password entered by the user are
+     used.  Cloudstack does a search for a user with the given
+     username. If it exists, it does a bind request with DN and
+     password.
+
+#. autoimport. A domain is configured to import any user if it does
+   not yet exist in that domain. For these users a account by the same
+   name as the user is created on the fly and the user is created in
+   that account.
+
+     To authenticate, domain, username and password entered by the
+     user are used.  If the domain is configured to be used with LDAP,
+     Cloudstack does a bind request with DN and password. If it exists
+     and authenticates it checks if a user with the given username
+     exists. If it doesn't exists, a account/user will be created with
+     the username as names for both account and user.
+
+#. autosync. A domain is configured to use a LDAP server and in this
