+ Additional LDAP filter:
+ LAM will automatically detect the right LDAP entries for each
+ account type. This can be used to further limit the number of
+ visible entries (e.g. if you want to manage only some specific
+ groups).

+ Hidden: This is used to
+ hide account types that should not be displayed but are required
+ by other account types. E.g. you can hide the Samba domains
