Related to a StackOverflow question I have. Since it's more or less really a SO question through and through, I won't go into the whole spiel. My platform question is this: Is there an industry standard somewhere that specifies how various aspects of PAM should operate?

No. There isn't. Looking at your tags: the PAM implementation on Solaris varies a fair bit from Linux' (or the other way around, since Solaris' version is older). – tink Jun 16 '13 at 19:46

It's specified by the OpenGroup (the body specifying Unix) and by the Linux Standard Base.

I don't know how well those are followed on the various Unices/Linuces though.

The Wikipedia page is also a good reference.
