This is a simple login manager to be used when authentication is done
using apache's LDAP capabilities. In addition to the normal
Foswiki::LoginManager::TemplateLogin
manager, this one adds a check to make sure the user is already cached
in LdapContrib, and that its name matches onto the configured naming conventions.
ClassMethod new($session)
Construct the LdapTemplateLogin object
ObjectMethod loadSession()
Load the session, sanitize the login name and make sure its user information are already
cached.
