Hi, all,
I am a newbie to linux authentication part.
Questions below really puzzle me:
[1] How to authenticate users from local storage(passwd shadow) and nis server?
(Without PAM)
getpwnam_r() will return a '*' in the pw_passwd field of "struct passwd".
I can parse /etc/shadow. But how can I do it on nis server? in my env, shadow file only contains local user info.
PLUS, how to maintain the session without PAM?
I have some experience in web development. There r some structure we can use to maintain the session. How to do it in a C/S design?
[2] Use pam to authenticate them.
My application is a c/s design. Suppose client needs to send the username/passwd to server with some tcp/udp pakages. Server uses pam to get it authenticated.
How to fulfill this?
Any examples? what if the client has a GUI? including for pam.d/my_application?
some pseudo codes will do.
Thanks a million.
