I have some trouble using passwd again.. I'd like to know what is causing it..
[r...@nixos:~]# passwd marc Changing password for marc. passwd: Permission denied When changing /etc/pam.d/passwd to use pam_permit.so only I can no longer enter a password and passwd just prints "password changed". so the passwd .. pam_unix2.so line in /etc/pam.d/passwd seems to be important. strace: http://rafb.net/p/7jq2vb43.html setrlimit(RLIMIT_NOFILE, {rlim_cur=RLIM_INFINITY, rlim_max=RLIM_INFINITY}) = -1 EPERM (Operation not permitted) The C code is: static void init_limits (void) { struct rlimit rlim; /* Don't create a core file. */ rlim.rlim_cur = rlim.rlim_max = 0; setrlimit (RLIMIT_CORE, &rlim); /* Set all limits to unlimited to avoid to run in any problems later. */ rlim.rlim_cur = rlim.rlim_max = RLIM_INFINITY; setrlimit (RLIMIT_AS, &rlim); setrlimit (RLIMIT_CPU, &rlim); setrlimit (RLIMIT_DATA, &rlim); setrlimit (RLIMIT_FSIZE, &rlim); setrlimit (RLIMIT_NOFILE, &rlim); setrlimit (RLIMIT_RSS, &rlim); setrlimit (RLIMIT_STACK, &rlim); } and doesn't check the return value. So this is not causing the failure. syslog looks like this: Mar 18 11:49:44 nixos passwd[6080]: pam_unix2(passwd:chauthtok): pam_sm_chauthtok() called Mar 18 11:49:44 nixos passwd[6080]: pam_unix2(passwd:chauthtok): username=[root] Mar 18 11:49:44 nixos passwd[6080]: User root: Permission denied I've tried compiling pwdutils with -g to be able to debug it using gdb to see where this message is thrown exactly. However gdb keeps saying: "no debugging symbols found". I'm using a hook to define env vars the same way its done running nix-build.. Is there anything which causes gcc (or libtool)? To remove those symbols again? objdum -h src/passwd-passwd.o shows lines such as .debug_line, .debug_info, .debug_loc ... So the .o file does have debugging symbols. file src/passwd says "not stripped" linking the executable using gcc -o ... -l... -l... passwd-passwd.o works fine. Result is the same? Do you have any ideas what else to try? Maybe I should setup ldap.
