I have a requirement to authenticate users of a our web application against Active Directory. The applicaiton is written using SEAM. I have never done anything with JAAS or with LDAP so I am having a hard time figuring this out. I have looked at LdapExtLoginModule http://wiki.jboss.org/wiki/Wiki.jsp?page=LdapExtLoginModule, but I am still too new to this to know if this is my best option. At this point I want to keep things as simple as possible: when a user types in a username and password I want to make sure that user and password is valid in Active Directory. For something this simple is LdapExtLoginModule the best way to go? Other than the Wiki page are there any other sources of documentation for doing this sort of thing?
