-# This file contains parameters used by Lemonldap::NG to find its configuration
-#
-#
-# 1 - Type
-#
-# You can use one of the following:
-# * File: you have to set 'dirName' parameter. Example:
-#
-#           type = File
-#           dirName = /var/lib/lemonldap-ng/conf
-#
-# * DBI : you have to set 'dbiChain' (required) and 'dbiUser' and 'dbiPassword'
-#         if needed. Example:
-#
-#           type        = DBI
-#           dbiChain    = DBI:mysql:database=lemonldap-ng;host=1.2.3.4
-#           dbiUser     = lemonldap
-#           dbiPassword = password
-#
-# * SOAP: SOAP configuration access is a sort of proxy: the portal is
-#         configured to use the real session storage type (DBI or File for
-#         example).
-#         You have to set 'proxy' parameter. Example:
-#
-#           type         = SOAP
-#           proxy        = https://auth.example.com/index.pl/config
-#           proxyOptions = { timeout => 5 }
-#           User         = lemonldap
-#           Password     = mypassword
-#
-# * LDAP: you have to set ldapServer, ldapConfBranch, ldapBindDN and ldapBindPassword.
-#
-#           type             = LDAP
-#           ldapServer       = ldap://localhost
-#           ldapConfBase     = ou=conf,ou=applications,dc=example,dc=com
-#           ldapBindDN       = cn=manager,dc=example,dc=com
-#           ldapBindPassword = secret
-#
-#
-# 2 - LocalStorage
-#
-# To increase performances, use a local cache for the configuration. You have
-# to choose a Cache::Cache module and set it's parameters (1 line). Example:
-#
-#           localStorage = Cache::FileCache
-#           localStorageOptions = { 'namespace' => 'MyNamespace', 'default_expires_in' => 600, 'directory_umask' => '007', 'cache_root' => '/tmp', 'cache_depth' => 5, }
