PAM completeness and standardization [PR:bin/71290]

[Daniel Bond]

Hi Steve and Oliver,

thanks for your replies. Sorry it has taken me some time to reply. I'm  
willing to put in some time into this issue too, maybe we could do a  
joint effort on this?

The problem report with the most information in is http://www.freebsd.org/cgi/query-pr.cgi?pr=bin/71290 
  - DES has some good reasons, for why the patch has not been included  
in FreeBSD.

Here are some of my viewpoints about the comments in the ticket.

- I think it is really important we preserve all command-line options,  
and do not break any existing functionality what so ever.
- I also think exposing PAM code for changing passwords is a good  
thing. Either we want PAM support in FreeBSD, or we don't. If we do,  
we need to support the PAM core features - exposing this code is  
necessary, and the code needs to be polished accordingly.
- The documentation changes is nice to have, let's think about this  
when we are happy with the other stuff.


I have a NetBSD 5.0 installation on my private server, I'll start  
looking at how they have implemented PAM.


Any comments? Pointers to code that would need cleanup? Anything we  
need to be extra careful with?


Best regards,

Daniel.
