Looks like I could use: PAM auth: http://jpam.sourceforge.net/
LDAP/AD auth: http://www.openldap.org/jldap/ The first is definitely OK (Apache license), but I'm not sure about the second one (OpenLDAP public license). Looks BSDish to me. It claims to support Windows auth and is officially provided by the OpenLDAP project. Has anyone used it? Thanks Ted
