This timeout will prevent an attacker from using a session that has been
inactive for too long.
This inactivity timeout combined with the timeout before expiration makes a
good combination of security mechanisms to prevent session theft.
If no activity timeout is provided, then the feature is disabled and only
session expiration remains as a protection.
Sometimes, LDAP organization is such that groups membership cannot be computed
with username only. User DN is required to retrieve groups.
e.g. user Joe has a username joe and a cn of Joe Blogs, resulting in a dn of
cn=Joe Blogs,ou=users,dc=example,dc=com which is needed to retrieve groups
but cannot be computed from joe only.
Issue was reported in issue #146
Basically, the ACL configuration was very static and it was not allowed
to remove 'any', 'groups', 'users'. The application crashed when those
keys did not exist.
After this fix, every key is optional and replaced by a default value
for the app configuration to be complete and used by Authelia.
Later, a configuration validator will be implemented to detect issues
with configuration at startup.
Previously, string "{0}" was replaced by the user dn in the groups_filter
attributes of the LDAP configuration.
However, if the groups children only have a memberUid attribute, one would
like to use the username instead of the user dn.
Since the user dn can be built from the username, "{0}" is now replaced
by the username instead of the user dn so that an LDAP relying on attribute
'memberUid' can be used.
Client and server now have their own tsconfig so that the transpilation is only
done on the part that is being modified.
It also allows faster transpilation since tests are now excluded from tsconfig.
They are compiled by ts-node during unit tests execution.
