I seem to remember the verify processing bumping up the password fail count and revoking the id without any additional logic - even returning codes indicating those issues.

I think if you were just going to take the password and verify that it was correct (or not), that shouldn't be a big issue.

Re: What were the first models to support Dual Address Space?
The 4341 was introduced in 1979 before DAS (1981), and was marketed primarily for its ability to run in ECPS:VSE mode to support DOS/VSE. GA24-3672-4_4341ProcessorMG1FunctionalCharacteristics under Programming Support says"programming support is provided by DOS/VSE, OS/VSl, OS/VS2-MVS, and VM/370". That doesn't preclude the possibility of adding DAS support later, and in fact the top of the 4341 line model group 12, introduced near the end of 1982, apparently did include DAS support as a standard feature (Ref: GC20-2102-2 Guide to the IBM 4381 Processor, p128, comparing features of a 4341 MG12 to features on 4381 models). Availability on at least one model is sufficient to demonstrate DAS support existence on a 4341. Joel C Ewing On 1/8/21 12:35 PM, Seymour J Metz wrote: > Thanks.

More detailed specs, please. Are you fundamentally looking for sample code to learn from, or something to [adapt and] use as-is? Programming language? Execution environment? (TSO session? UNIX session? Some other environment?) Is this a program to run in an existing session to verify that the user at the keyboard knows the password that was used at logon? (TSS has a TSO command to lock the screen and prompt for the password upon resuming. It would be easy enough to write a similar command for any of the security systems.) Or is it a program that accepts both a userid and password at the keyboard (or in a batch job), and verifies that they are a good match? Or something else I'm not thinking of? Any program that accepts userids and passwords needs to have controls to prevent its use to try many passwords without penalty. Generally the required security system calls require at least an APF authorized state to make this query, for the reason above. > I'd like to see code that does this, for ACF2 and Top Secret as > well, but I'm primarily interested in RACF. If you use the SAF (RACROUTE REQUEST=VERIFY) approach, it should work identically for all three security systems. Your code has to decide if what you are verifying is a password or a phrase. If you are using an LE language (C, PL/I, ...) there is a library function __passwd(...) to do this. If you are writing in assembler, probably the easiest to use is IRRSPW00, documented in the RACF Callable Services book. IRRSPW00 may not work in the CA security systems - I'm not sure. Both the above assume password vs phrase based on the length.

Re: Code to verify LOGON password
Something about this makes me nervous. At a minimum you need @Gils's suggestion that the password not exist in your address space (or if it does you really, really know what you are doing).

Re: ZFS using zEDC hardware compression
I just RTFM. No VSAM dataset can be compressed using zEDC. Of course VSAM datasets dumped with DFSMSdss may be compressed, because: a) output dataset is PS, which is eligible for zEDC compression. b) dss itself can use zEDC to compress data written to output. Such dataset can be writted on tape or disk. There is no reason to make it zEDC compressible. -- Radoslaw Skorupka Lodz, Poland W dniu 08.01.2021 o 17:20, PINION, RICHARD W. pisze: That's a definitive answer, thanks. -Original Message- From: IBM Mainframe Discussion List On Behalf Of Seymour J Metz Sent: Friday, January 8, 2021 11:08 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: ZFS using zEDC hardware compression [External Email.
