In order to simplify the deployment of Authelia for
testing, LDAP is now optional made optional thanks
to users database stored in a file. One can update
the file manually even while Authelia is running.
With this feature the minimal configuration requires
only two components: Authelia and nginx.
The users database is obviously made for development
environments only as it prevents Authelia to be scaled
to more than one instance.
Note: Configuration has been updated. Key `ldap` has
been nested in `authentication_backend`.
This commit should fix#225.
In order to avoid stalling LDAP connections, Authelia creates new
sessions for each set of queries bound to one authentication, i.e.,
one session for authentication, emails retrieval and groups
retrieval.
Before this commit, a failing query was preventing the session to
be closed (unbind was not called). Now, unbind is always called
whatever the outcome of the query.
I took the opportunity of this commit to refactor LDAP client in
order to prepare the work on users database stored in a file.
(#233)
