Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V6.1 * * * **************************************************************** * PROBLEM DESCRIPTION: java.lang.NullPointerException when * * using CTG logon module on z/OS * * * **************************************************************** * RECOMMENDATION: * **************************************************************** CICS Transaction Gateway, has implemented a login module on WAS which is used to pass credential information through the CICS Transaction Gateway Resource Adapter to CICS. This works fine on distributed, but doesn't work on z/OS. The problem is that on z/OS, the j2c code is calling zOS-specific security API's that attempt to create a UTOKEN credential (RACF security token) to use as the J2C subject. This fails because we don't have a PlatformCredential since they have configured LDAP as the user registry.
Problem conclusion
Code has been added to determine if SAF authorization is enabled and based on it appropriate security helper will be used to overcome the issue. APAR PM20074 is currently targeted for inclusion in Service Level (Fix Pack) 6.1.0.33 of WebSphere Application Server V6.1. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
