Hi everyone.

Two questions, first, I use UNIXMAP to have control on the OMVS asigning, UID and GID. But I have heard that IBM recomends to don´t use it anymore...
Is this correct?

If I still use UNIXMAP is it correct to have more than 1 user using a UID? Or more than one group using a GID?

Thanks

I think VLF (virtual lookaside facility) is IBM's preferred method of doing Unix id look ups, but it doesn't appear that UNIXMAP will be going away any time soon.

It is never a good idea to have multiple people sharing a user id or multiple groups sharing a group id. This violates security standards and does not allow for identification of who did what.

Thanks Robert

I'll look to VLF.
