I used this post to set up ldap auth: http://jasperforge.org/plugins/mwiki...iguration#LDAP i also put spring-ldap-1.3.0.RELEASE-all.jar into 'lib' folder, checked permissions. furthermore, I have got the latest jasperserver 3.7.0, and internal auth working great. but when I modify applicationContext-security.xml, it doesnt start. here is my log when starting jasperserver: http://pastebin.com/m758d17de applicationContext-security.xml Code: ========================== SOLVED in new version there is no class: "org.springframework.security.providers.ldap.populator.DefaultLdapAuthoritiesPopulator" there is a class: class="org.springframework.security.ldap.populator.DefaultLdapAuthoritiesPopulator" Post Edited by andreika at 01/22/2010 08:15 Post Edited by andreika at 01/22/2010 08:15
