Description/symptom of problem: PK68161 resolves the following problem: ERROR DESCRIPTION:? After applying Fixpack 6.1.0.17 the node agent fails to start when global security is enabled. LTPAServerObj E SECJ0373E: Cannot create credential for the user "" due to failed validation of the LTPA token. The exception is com.ibm.websphere.security.EntryNotFoundException: SecurityName is null LOCAL FIX:? None PROBLEM SUMMARY:? USERS AFFECTED: All users of WebSphere Application Server with standalone Lightweight Directory Access Protocol (LDAP) user registry PROBLEM DESCRIPTION: After applying Cumulative Fix 17, the node agent fails to handle incoming requests. RECOMMENDATION: None Due to code defect, one of custom properties is enabled by default. The security code then invokes the incorrect method while constructing WSCredential. As a result, the security code fails to authenticate users. PROBLEM CONCLUSION:? With this fix, when the custom property does not exist, the security code uses the original method to construct WSCredential. The fix for this APAR is currently targeted for inclusion in fixpack 6.1.0.19.
