You get 108 characters to play with in "classic" RACF: up to 8 for the user ID and up to 100 for the (mixed case) passphrase. Passphrases are available with the z/OS Security Server in z/OS 1.8 and higher (z/OS 1.9 and higher if you also want TSO/E to play along). But that's not the real limit. All the way back in OS/390 2.4, in September, 1997, IBM added client certificate authentication to RACF. That support has been updated and improved ever since. With client certificate authentication you can do all sorts of "exotic" things rather straightforwardly, including smartcards and voice IDs. Digital certificates with key sizes of 4,096 bits are common now. And there's the aforementioned IBM Directory Server for z/OS, part of the base z/OS operating system. -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM Z & LinuxONE, Multi-Geography E-Mail: sipp...@sg.ibm.com ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
