* Add auth_ad_(group|user)_filter options
* use global
* Fix some AD annoyances
Use the power of the LDAP filter to minimize the number of queries and
hopefully help performance in get_userlist, change semantics of
auth_ad_(user|group)_filter in $config to be anded with
samaccountname=USERNAME.
* remove unused variable
* update documentation
* Update Authentication.md
* Update Authentication.md
Added note for SELinux users with LDAP/AD and Active Directory redundancy
* Update Authentication.md
Remove extra whitespace
This Authentitation / Authorization module provides the ability to let
the webserver (e.g. Apache) do the user Authentication (using Kerberos
f.e.) and let libreNMS do the Authorization of the already known user.
Authorization and setting of libreNMS user level is done by LDAP group
names specified in the configuration file. The group configuration is
basicly copied from the existing ldap Authentication module.
To save lots of redundant queries to the LDAP server and speed up the
libreNMS WebUI, all information is cached within the PHP $_SESSION as
long as specified in $config['auth_ldap_cache_ttl'] (Default: 300s).
