Linux/390 has security functionality; however there are a number of reasons to integrate this into CA ACF2 with the CA PAM Client for Linux for zSeries product.
Reasons to integrate Linux Security with CA ACF2 using the CA PAM Client for Linux for zSeries product.
Just to reiterate reason 1, we worked with a client who was in the process of setting up approximately 1000 Linux/390 LPARs. The administrative effort to maintain user id/pswds in the nodes would require a number of administrators. While a site's organization might not be looking at this many, We will venture a guess and say that we doubt the administrative staff is growing to service security requirements. This alone should be reason enough to add a very thin layer to enhance and centralize the security in a site's environment.
