 * Any known limitations, constrains or stuff not working, such as (but not limited to):
     * There is currently **no SSO integration** though it might be integrated at some point in the app, now that it's supported in Meteor/Wekan. In the meantime, users can create accounts (in fact, they can create infinite number of accounts) manually, and need to login manually specifically in Wekan.
     * This app **only works on x86, 64bits architecture**! In particular, it won't work on 32 bit machines or ARM. See the discussion [here](https://github.com/YunoHost-Apps/wekan_ynh/issues/1#issuecomment-401612500).
+    * YunoHost users with more than one email address can't login to wekan using ldap. For example first YunoHost user has severals email addresses: root@domain; admin@domain; webmaster@domain; postmaster@domain, etc... Workaround: remove all mail aliases of the user you want to connect, connect one time on wekan, recreate the aliases of the YunoHost user.
 
 ## Configuration:
 As LDAP authentification is enabled by default, Wekan admins correspond to the permission `Wekan Admin`. The user you choose during installation is member of this group.
