Security configuration and enablement errors

Use this information to troubleshoot problems with configuring or enabling security.

New feature: Beginning in WAS v8.0 you can configure the server to use the High Performance Extensible Logging (HPEL) log and trace infrastructure instead of using SystemOut.log , SystemErr.log, trace.log, and activity.log files or native z/OS logging facilities. If you are using HPEL, you can access all of your log and trace information using the LogViewer command-line tool from your server profile bin directory. See the information about using HPEL to troubleshoot applications for more information on using HPEL.New feature:

"LTPA password not set. validation failed" message displayed as error in the administrative console after saving administrative or application security settings

This error can be caused if, when configuring WAS security, LTPA is selected as the authentication mechanism and the LTPA password field is not set.

To resolve this problem:



The setupClient.bat or setupClient.sh file is not working correctly

The setupClient.bat file on Windows operating systems and the setupClient.sh file on Linux and UNIX-based platforms incorrectly specify the location of the SOAP security properties file.

(Windows) In the setupClient.bat file, the correct location is: 

set CLIENTSOAP=-Dcom.ibm.SOAP.ConfigURL=file:%WAS_HOME%/properties/soap.client.props

(AIX) In the setupClient.sh file, the CLIENTSOAP variable is: 

CLIENTSOAP=-Dcom.ibm.SOAP.ConfigURL=file:WAS_HOME/properties/soap.client.props

In the setupClient.bat and the setupClient.sh files, complete the following steps:

  1. Remove the leading slash ( / ) after file:.
  2. Change sas to soap.


Java HotSpot Server VM warning: Unexpected Signal 11 occurred under user-defined signal handler 0x7895710a message occurs in the native_stdout.log file when enabling security on the HP-UX11i platform

After you enable security on HP-UX 11i platforms, the following error in the native_stdout.log file occurs, along with a core dump and WAS does not start: 

Java HotSpot(TM) Server VM warning:
Unexpected Signal 11 occurred under user-defined signal handler 0x7895710a
To work around this error, apply the fixes recommended by Hewlett Packard for Java at the following URL: http://www.hp.com/products1/unix/java/infolibrary/patches.html.


WAS v6 is not working correctly with Enterprise Workload Manager (EWLM)

To use WAS v6 with EWLM, manually update the WAS server.policy files. For example: 

grant codeBase "file:/
<EWLM_Install_Home>/classes/ARM/arm4.jar" {
 permission java.security.AllPermission;
};
Otherwise, you might encounter a Java 2 security exception for violating the Java 2 security permission.

Refer to server.policy file permissions for more information on configuring server.policy files.

NMSV0610I: A NamingException is being thrown from a javax.naming.Context implementation

If you use CSIv2 inbound authentication, basic authentication is required, and Java clients running with com.ibm.CORBA.validateBasicAuth=true might fail with the following exception: 

If you use CSIv2 inbound authentication, basic authentication is required, and Java™
clients running with com.ibm.CORBA.validateBasicAuth=true might fail with the following exception:

NMSV0610I: A NamingException is being thrown from a javax.naming.Context
           implementation. Details follow:

SECJ0395E: Could not locate the SecurityServer at host/port:9.42.72.27/9100
to validate the userid and password entered. You may need to specify valid
securityServerHost/Port in (WAS_INSTALL_ROOT)/properties/sas.client.props file.

To fix this problem, modify the com.ibm.CORBA.validateBasicAuth=false property in the client's sas.clients.props file, which is located in WAS_HOME/profiles/ <profile-name>/properties, and then run the client.


When administrative security is enabled but application security is not enabled, the performance servlet displays authorization errors and cannot provide statistics

In WAS Version 6.1, when administrative security is enabled, the administration service is locked down. However, if application security is not enabled, an authentication challenge does not occur for incoming requests and, consequently, credentials do not exist for the performance servlet to access the administration service.

If administrative security is enabled, you also must enable application security for the performance servlet to process incoming requests.


"Name value is invalid" displays when migrating users and groups after the JACC provider for Tivoli is configured

When you use the migrateEAR utility to migrate the changes that were made to console users and groups after the JACC provider for Tivoli Access Manager is configured, the following configuration error displays in the systemOut.log file. 

<specialSubjects> name is invalid

The migrateEAR utility migrates the user and group data that is contained in the admin-authz.xml file. However, the migrateEAR utility does not convert the XML tags that are listed in the admin-authz.xml file if the pdwas-admin group is added to the administrator access control list (ACL) in Tivoli Access Manager prior to migration.

To resolve this error, run in padadmin to check whether the pdwas-admin group is in the administrator ACL before you migrate: 

acl show
_WebAppServer_deployedResources_Roles_administrator_admin-authz_ACL

The following result should display: 

ACL Name:
_WebAppServer_deployedResources_Roles_administrator_admin-authz_ACL
Description: Created by the Tivoli Access Manager for Websphere Application Server Migration Tool.
Entries:
User sec_master TcmdbsvaBR1
Group pdwas-admin T[WebAppServer]i

If the pdwas-admin group is not listed, then run in pdadmin to modify the ACL to add the pdwas-admin group: 

acl modify
_WebAppServer_deployedResources_Roles_administrator_admin
-authz_ACL set gruop pdwas-admin T [WebAppServer]i


A Sun JDK can not read a PKCS12 keystore created by the Application Server

A Sun JDK is not able to read a PKCS12 keystore created by the Application Server. The reason for this is that the PKCS12 implementation used by the IBM SDK and the Application Server is different than the implementation used by the Sun JDK. The difference causes problems when a Sun JDK is used to read the default trustore, trust.p12, or keystore, key.P12 created by the Application Server.

Because the truststore can not be read by the Sun JDK, first extract the certificates from the trustore using an IBM SDK. We can then import these certificates into a keystore that the Sun JDK can recognize correctly, such as a JKS keystore.


Call a secure resource from a non-secure resource is not supported when the non-secure resource collects data from users and then posts this data to the secure resource

If we have a non-secure resource (such as a JSP or a servlet) that calls a secure resource, the application might fail if the non-secure resource collects data from users and then posts this data to secure JSP or servlet files for processing.

To avoid this situation, structure your web application so that users are forced to login before the application performs any HTTP POST actions to the secure JSP or servlet files. To accomplish this, secure the first resource using whatever security mechanism that you choose (such as basic auth, form-login or cert).

This restriction is because basic auth and form-login use the servlet sendRedirect method, which has several implications for the user. The sendRedirect method is used twice during basic auth and form-login.

The sendRedirect method initially displays the basic auth or form-login page in the web browser. It later redirects the web browser back to the originally requested protected page. The sendRedirect(String URL) method tells the web browser to use the HTTP GET request to access the page specified in the web address. If HTTP POST is the first request to a protected JSP or servlet file, and no previous authentication or login occurred, then HTTP POST is not delivered to the requested page. However, HTTP GET is delivered because basic auth and form-login use the sendRedirect method, which behaves as an HTTP GET request which attempts to display a requested page after a login occurs.
