Subject java.net.UnknownHostException: Failed to negotiate with a suitable domain controller for xxx
Date Thu, 01 Aug 2013 08:25:42 GMT
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

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
