Does anyone know an easy way to make users do a login before enetering the wiki? Can this be done without an LDAP server etc (which I know nothing about...) ?

In an earlier project we used an older version of VQWiki and i think we let Tomcat do the autorization somehow. Usernames and passwords were written in a Tomcat config file i think. Is this still possible and if so, is there any documentation explining how to do this? I have been looking in the VQWiki book but couldn't fint it there or anywhere else for that matter.
