Thanks all. I use now Ubuntu 17.04 for the client and Ubuntu 16.06 LTS for the server. So as I understand LDAP can only be used for authentication and for autortication I have to look for other software.
LDAP can be used for both authz and authc if the software in question was well written. If the software in question was poorly written, it probably won't be possible. But that is not an LDAP limitation, that is a limitation due to the software developer.
