Add target limitations to PV_SU in AIX RBAC

If one of the PV_SU kernel privileges is used any target user id can be reached by a privileged command.

There is currentliy no limitation to the list of target user id's for the su command.

It would be great to get a way to limit the target user-id's that the user can switch to.

    An idea for the implementation could be to use RBAC domains. For example, if a user has a specific RBAC domain assigned, the RBAC domain could limit the list of users that a requester can SU to. A stanza-based file could list the stanza of an RBAC domain name and the values could be user ids. When a script/executable that is a privileged command in RBAC uses needs to su into a user account, the Kernel could check if the requester has a domain assigned that allows the requester to switch to the target user.

    Example:

    /etc/security/privsu

    domainsu1:

    sapadmin

    fwadmin


    domainsu2:

    webadmin

    dbadmin


    A kernel privilege could be created, i.e. PV_SU_LIMIT, that is assigned as an innate privilege to a privileged command.

    If a calling user runs the privileged command and the command performs a su, the domain is checked and if the target user of the su operation is listed in one of the assigned domains, the su succeeds.
