This article describes the issues you might encounter using a Java Authorization Contract for Containers (JACC) authorization provider. Tivoli Access Manager (TAM) is bundled with WAS as an authorization provider. However, you also can plug in your own authorization provider.

 

Use TAM as a JACC authorization provider

You might encounter the following issues when using TAM as a JACC authorization provider:

 

Use an external provider for JACC authorization

You might encounter the following issues when you use an external provider for JACC authorization:

 

The configuration of JACC might fail

If you are having problems configuring JACC, check the following:

 

The server might fail to start after configuring JACC

If the server does not start after JACC has been configured, check the following:

 

The application might not deploy properly

When you click Save, the policy and role information is propagated to the TAM policy. It might take some time to finish. If the save fails, uninstall the application and then reinstall it.

To access an application after it is installed, wait 30 seconds (by default) to start the application after you save.

 

The startServer command might fail after you have configured TAM or a clean uninstall did not take place after unconfiguring JACC.

If the cleanup for JACC unconfiguration or start server fails after JACC has been configured, do the following:

 

An "HPDIA0202w An unknown user name was presented to Access Manager" error might occur

You might encounter the following error message if you are attempting to use an existing user in a LDAP user registry with TAM:

AWXJR0008E Failed to create a PDPrincipal for principal mgr1.:
AWXJR0007E A TAM exception was caught. Details are:
"HPDIA0202W An unknown user name was presented to Access Manager."

This problem might be caused by the hostname exceeding predefined limits with Tivoli Access Manager when it is configured against MS Active Directory. In WebSphere v6, the maximum length of the hostname can not exceed 46 characters.

Check that the hostname is not fully qualified. Configure the machine so that the hostname does not include the host domain.

To correct this error, complete the following steps:

  1. On the command line, type the following information to get a TAM command prompt:

    pdadmin -a administrator_name -p administrator_password

    The pdadmin administrator_name prompt is displayed. For example:

    pdadmin -a administrator1 -p password

  2. At the pdadmin command prompt, import the user from the LDAP user registry to TAM by typing the following information:

    user import user_name cn=user_name,o=organization_name,c=country

    For example:

    user import jstar cn=jstar,o=ibm,c=us

After importing the user to TAM, use the user modify command to set the user account to valid. The following syntax shows how to use this command:

user modify user_name account-valid yes

For example

user modify jstar account-valid yes

For information on how to import a group from LDAP to TAM, see the TAM documentation.

 

An "HPDAC0778E The specified user's account is set to invalid" error might occur

You might encounter the following error message after you import a user to TAM and restart the client

AWXJR0008E   Failed to create a PDPrincipal for principal mgr1.: 
AWXJR0007E   A TAM exception was caught. 
Details are: "HPDAC0778E   The specified user's account is set to invalid."

To correct this error, use the user modify command to set the user account to valid. The following syntax shows how to use this command

user modify user_name account-valid yes
For example

user modify jstar account-valid yes

 

An "HPDJA0506E Invalid argument: Null or zero-length user name field for the ACL entry" error might occur

You might encounter an error similar to the following message when you propagate the security policy information from the application to the provider using the wsadmin command propagatePolicyToJACCProvider

AWXJR0035E   An error occurred while  attempting to add member, cn=agent3,o=ibm,c=us, to role AgentRole
HPDJA0506E   Invalid argument: Null or zero-length user name field for the ACL entry

To correct this error, create or import the user, which is mapped to the security role to the TAM. For more information on propagating the security policy information, see the documentation for your authorization provider.

 

An WASX7017E: Exception received while running file "InsuranceServicesSingle.jacl" error might occur

After the JACC provider and TAM are enabled, when attempting to install the application (which is configured with security roles using the wsadmin command), the following error might occur

WASX7017E: Exception received while running file "InsuranceServicesSingle.jacl"; exception information:
 com.ibm.ws.scripting.ScriptingException: WASX7111E: Cannot find a match for supplied option: 
"[RuleManager, , , cn=mgr3,o=ibm,c=us|cn=agent3,o=ibm,c=us, cn=ManagerGro
up,o=ibm,c=us|cn=AgentGroup,o=ibm,c=us]" for task "MapRolesToUsers

The $AdminApp task option MapRolesToUsers becomes invalid when TAM is used as the authorization server. To correct the error, change MapRolesToUsers to TAMMapRolesToUsers.
