[9fans] p9cr support in p9p's factotum?

["Ashwin Ganti" <ashwin.ganti@gmail.com>]

Hello,

As part of a PAM module implementation in Linux I need to authenticate
against p9p's factotum. The code basically does an
"auth_userpasswd(user, passwd)" to achieve this. Apparently I get a
response from the factotum saying that it does not understand p9cr.

I noticed that in p9p's 'libauth' sources the auth_userpasswd
internally calls auth_challenge("user=%q proto=p9cr role=server",
user). When I grepped the sources I could not find p9cr implemented in
src/cmd/auth/factotum. Although I could notice a file "p9cr.c" which
seems to be a partial port as the code is not the same as that of its
Plan9 counterpart but looks more like the other p9p's code ( p9sk1.c
etc. ).

I was wondering if p9cr is supported in p9p's factotum. If yes then am
I missing something here? If not then is it on somebody's plate to
complete it? I am willing to complete it but I am a newbie in the
p9p's factotum's code and would appreciate any guidance/help from
someone who is aware of this stuff to help me get it done.

I would also like to know if there is any workaround for this like
using another protocol may be?

Any information would be very much useful.

Thanks and regards,
