This gollum supports authenticated users using LDAP. To activate authentication set :ldap, e.g.:
Precious::App.set(:ldap, {
:host => "10.130.0.8",
:port => 389,
:base => "cn=%s,ou=People,dc=metameute,dc=de"
}
)
You may also set a wiki to be private, i.e. it can only be edited by authenticated users.
Precious::App.set(:private, true)
