With OA47269 & OA49446 applied, authority is checked for a PATH, or AIX that is being defined. However, authority is not checked for the base cluster. This can lead to authorization failues once a base cluster is accessed via a PATH or AIX by a user or application that has authority to the PATH & AIX, but not the base cluster.
What is needed in ACF2 for IBM apar UA83944?
The IBM fix introduced a new facility class STGADMIN.IGG.CATALOG.SECURIY.BOTH. Users having READ authority to STGADMIN.IGG.CATALOG.SECURIY.BOTH are required to have ALTER authority to both the CLUSTER and the PATH or AIX when defining a path or AIX. This ensures sufficient authority to both the CLUSTER and AIX or PATH on subsequent VSAM OPENs. Problem is resolved when PTFs are applied and READ authority is established to STGADMIN.IGG.CATALOG.SECURIY.BOTH for all users.
A sample ACF2 rule would look like this:
IGG.CATALOG.SECURIY.BOTH UID(-) SERVICE(READ) ALLOW
