hi jboss team, i've read a lot of threads on this forum but i am not abble to authenticate my user silently. I'm using the jboss 4.0.5.GA version with the jems installer in the ejb3 configuration. The final purpose is to validate some security point for a futur project. I have done all the configuration given on this page: http://wiki.jboss.org/wiki/Wiki.jsp?page=NegotiateKerberos Once jboss has started, i'm trying to access to my "secured" web application using IE 7.0 (i have also set the correct security level in IE); i obtained the following error in the server.log : 2007-01-08 14:07:58,265 INFO [org.jboss.system.server.Server] JBoss (MX MicroKernel) [4.0.5.GA (build: CVSTag=Branch_4_0 date=200610162339)] Started in 33s:313ms | 2007-01-08 14:08:23,671 DEBUG [org.jboss.security.plugins.JaasSecurityManager.SPNEGO] CallbackHandler: org.jboss.web.tomcat.security.AdvancedWebCallbackHandler@70cdd2 | 2007-01-08 14:08:23,671 DEBUG [org.jboss.security.plugins.JaasSecurityManagerService] Created securityMgr=org.jboss.security.plugins.JaasSecurityManager@1d8c046 | 2007-01-08 14:08:23,671 DEBUG [org.jboss.security.plugins.JaasSecurityManager.SPNEGO] CachePolicy set to: org.jboss.util.TimedCachePolicy@1376afa | 2007-01-08 14:08:23,671 DEBUG [org.jboss.security.plugins.JaasSecurityManagerService] setCachePolicy, c=org.jboss.util.TimedCachePolicy@1376afa | 2007-01-08 14:08:23,671 DEBUG [org.jboss.security.plugins.JaasSecurityManagerService] Added SPNEGO, org.jboss.security.plugins.SecurityDomainContext@15075f9 to map | 2007-01-08 14:08:30,781 DEBUG [org.jboss.web.tomcat.security.HttpServletRequestResponseValve] Realm returned: null I was thinking that the realm in an AD environnement was the domain name, what is the realm in an NTLM environnement ?
