I'm studying on
pam library , and I run the code given by "The Linux-PAM Application
Developer's Guide" on redhat linux.
"retval =
pam_authenticate(pamh, 0);" is running successfully
but the next
"retval = pam_acct_mgmt(pamh, 0);" return "PAM_AUTHINFO_UNAVAIL"
I don't know
what problem is it? Please do me a favour.
Thank you very
much
Chu,
there are several things in your program to be checked:
- have you already defined the 'service' 'check_user' in your pam.d
directory?
If not, the behaviour will fall back to service 'other', which may be
missing too.
- Does your conversation function 'conv' as defined in pam_start()
work well, i.e.
does it query for a password? If not, you must supply a password via
pam_set_item()
to make pam_authenticate work.
I suggest, you go and start a debugger (gdb) to look for what your
example program
is doing in detail.
Regards,
Andreas
