Hi, I am not sure if this is the right List to post this on, please advise if it isn't and let me know where is best to post.
I am getting the following error on one of our applications running on our intranet: 2013-07-31 17:15:11,180 [http-xxx.xxx.x.xxx-xx-x] ERROR org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/forms].[action] - Servlet.service() for servlet action threw exception java.net.UnknownHostException: Failed to negotiate with a suitable domain controller for xxx.LOCAL at jcifs.smb.SmbSession.getChallengeForDomain(SmbSession.java:187) at jcifs.http.NtlmHttpFilter.negotiate(NtlmHttpFilter.java:150) at jcifs.http.NtlmHttpFilter.doFilter(NtlmHttpFilter.java:114) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:215) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:465) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.authenticator.SingleSignOn.invoke(SingleSignOn.java:393) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:837) at org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:640) at org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java:1287) at java.lang.Thread.run(Unknown Source) In my tomcat/conf/server.xml file I have: <Realm className="com.viatel.tomcatrealms.ADJNDIRealm" debug="01" resourceName="ActiveDirectory" connectionURL="ldap://xxx:xxx" alternativeURL="ldap://xxx:xxx" connectionName="LDAP@xxx.local" connectionPassword="xxx" referrals="follow" userBase="dc=vtlwavenet,dc=local" userSearch="(sAMAccountName={0})" userSubtree="true" roleBase="dc=xxx,dc=local" roleSearch="(member={0})" roleName="cn" roleSubtree="true" /> I have 2 .war files running from this tomcat - 1) intranet portal A, 2) intranet helpdesk page and also another intranet portal B (both run from slightly different URLs). When tomcat was restarted the intranet portal A runs, intranet portal B runs but the intranet helpdesk portal doesn't run. For this we get the error message shown above. I don't know if it is the java code, some setting in the tomcat catalina base or if it is a tomcat network issue. We are running Tomcat 5.5.29. java version "1.5.0_22" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_22-b03) Java HotSpot(TM) Client VM (build 1.5.0_22-b03, mixed mode, sharing) It is on a Windows Server 2003 R2 SP2 VM box. Any help on this is appreciated. Thanks in advance Seema
