java.net.UnknownHostException

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • If one of domain contollers is not available (or there is a wrong entry in SRV records in DNS), and Hudson receives such name from DNS, it tries to bind to LDAP with this one domain controller only and does not even try to fall back to other domain controllers listed in SRV records. Expected behavior: When UnknownHostException (or CommunicationException) is caught, retry binding with another domain controller listed in SRV records. Below is a stack trace from console when this problem happens. Note that <domain> is just a placeholder for a real domain name. Also there is a typo: "and could not authenticat against any" should read "and could not authenticate against any" Aug 19, 2009 1:50:08 PM hudson.plugins.active_directory.ActiveDirectoryUnixAuthenticationProvider retrieveUser WARNING: Failed to bind to LDAP javax.naming.CommunicationException: zhk25dsdc11.<domain>.:389 [Root exception is java.net.UnknownHostException: zhk25dsdc11.<domain>.] at com.sun.jndi.ldap.Connection.<init>(Connection.java:207) at com.sun.jndi.ldap.LdapClient.<init>(LdapClient.java:118) at com.sun.jndi.ldap.LdapClient.getInstance(LdapClient.java:1580) at com.sun.jndi.ldap.LdapCtx.connect(LdapCtx.java:2616) at com.sun.jndi.ldap.LdapCtx.<init>(LdapCtx.java:287) at com.sun.jndi.ldap.LdapCtxFactory.getUsingURL(LdapCtxFactory.java:175) at com.sun.jndi.ldap.LdapCtxFactory.getLdapCtxInstance(LdapCtxFactory.java:134) at hudson.plugins.active_directory.ActiveDirectoryUnixAuthenticationProvider.retrieveUser(ActiveDirectoryUnixAuthenticationProvider.java:102) at hudson.plugins.active_directory.ActiveDirectoryUnixAuthenticationProvider.retrieveUser(ActiveDirectoryUnixAuthenticationProvider.java:73) at org.acegisecurity.providers.dao.AbstractUserDetailsAuthenticationProvider.authenticate(AbstractUserDetailsAuthenticationProvider.java:119) at org.acegisecurity.providers.ProviderManager.doAuthentication(ProviderManager.java:195) at org.acegisecurity.AbstractAuthenticationManager.authenticate(AbstractAuthenticationManager.java:45) at org.acegisecurity.ui.webapp.AuthenticationProcessingFilter.attemptAuthentication(AuthenticationProcessingFilter.java:71) at org.acegisecurity.ui.AbstractProcessingFilter.doFilter(AbstractProcessingFilter.java:252) at hudson.security.ChainedServletFilter$1.doFilter(ChainedServletFilter.java:87) at org.acegisecurity.ui.basicauth.BasicProcessingFilter.doFilter(BasicProcessingFilter.java:173) at hudson.security.ChainedServletFilter$1.doFilter(ChainedServletFilter.java:87) at org.acegisecurity.context.HttpSessionContextIntegrationFilter.doFilter(HttpSessionContextIntegrationFilter.java:249) at hudson.security.HttpSessionContextIntegrationFilter2.doFilter(HttpSessionContextIntegrationFilter2.java:66) at hudson.security.ChainedServletFilter$1.doFilter(ChainedServletFilter.java:87) at hudson.security.ChainedServletFilter.doFilter(ChainedServletFilter.java:76) at hudson.security.HudsonFilter.doFilter(HudsonFilter.java:155) at winstone.FilterConfiguration.execute(FilterConfiguration.java:195) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:368) at winstone.RequestDispatcher.forward(RequestDispatcher.java:333) at winstone.RequestHandlerThread.processRequest(RequestHandlerThread.java:244) at winstone.RequestHandlerThread.run(RequestHandlerThread.java:150) at java.lang.Thread.run(Thread.java:619) Caused by: java.net.UnknownHostException: zhk25dsdc11.<domain>. at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:177) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) at java.net.Socket.connect(Socket.java:518) at java.net.Socket.connect(Socket.java:468) at java.net.Socket.<init>(Socket.java:365) at java.net.Socket.<init>(Socket.java:179) at com.sun.jndi.ldap.Connection.createSocket(Connection.java:349) at com.sun.jndi.ldap.Connection.<init>(Connection.java:184) ... 27 more Aug 19, 2009 1:50:08 PM hudson.plugins.active_directory.ActiveDirectoryUnixAuthenticationProvider retrieveUser WARNING: Credential exception tying to authenticate against <domain> domain org.acegisecurity.BadCredentialsException: Either no such user 'akm022@<domain>' or incorrect password;
