Hi all,
I´m studying PAM and now I´m facing a dilemma: I want to create a small program like "/bin/passwd", to allow one user to change his/her shadowed password or someone´s password based on pre-defined polices (Ok, I know it was already built, but I want to know the details abou PAM, GETPWNAM, etc).
I have found source from shadow-utils, PAM, passwd, et cetera, and in almost all of them, the I/O handling is made by shadowio.c, passwdio.c or commonio.c, from "Julianne Frances Haugh" source.
My questions are:
Do I must get those files and compile them with my own source, or is there a lib or another way to use functions like spw_update, spw_lock to do the job ?
How is the "link" between a programa like mine (to allow a user to change your own password) and PAM ? For example, in Julianne's passwd.c there are a lot of "#ifndef USE_PAM" but, for what ? I didn't understand the context at all.
I'm not sure that my questions are clear, but any help is welcome!
Thanks in advance,
