Hello, I am having a bit of trouble getting PAM to work on a Slackware (8.0) machine. I downloaded the latest PAM source (0.75) and compiled/installed it. Then I read trough the How-To that I found on www.kernel.org and I think I somewhat got the idea of PAM but I do have some trouble getting it to work or so it seems. I'm not really interested yet to make the whole machine PAM dependant, that is I only want to use PAM for certain applications (mainly Apache and poppassd for now). After I installed it I made a /etc/pam.d directory and stored a text file named other inside: > cat /etc/pam.d/other # # default pam configuration # auth required /lib/security/pam_warn.so auth required /lib/security/pam_deny.so account required /lib/security/pam_warn.so account required /lib/security/pam_deny.so password required /lib/security/pam_warn.so password required /lib/security/pam_deny.so session required /lib/security/pam_deny.so session required /lib/security/pam_warn.so I don't have a /etc/pam.conf file as I'm not interested in running ftpd or login or any other "vital" daemon with PAM so I presume it is safe in my case not to have this config file? (feel free to correct me at any stage) After that I decided to test PAM with the small programs that come with the distribution. I found a small application named blank (Linux-PAM-0.75/examples/blank.c) and ran it. > /install/Linux-PAM-0.75/examples/blank ==> called pam_start() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' ==> called pam_putenv() got: `Success' a test: c=[gamma], j=[mu] Who are you? root ==> called pam_authenticate() got: `Authentication failure' ./blank: invalid request ==> called pam_end() got: `Success' As far as I understood from this, PAM started ok, and ended ok but the authentication failed. After looking at the logs this is the only message I found: Apr 22 14:12:55 gumb PAM-warn[2281]: service: blank [on terminal: <unknown>] Apr 22 14:12:57 gumb PAM-warn[2281]: user: (uid=0) -> root [remote: ?nobody@?nowhere] After that I decided to try poppassd (from Mr. Pawel Krawczyk, poppassd-ceti-1.8-1). Based on what I read in the How-To and some information I found on the WWW I created a config file for it in /etc/pam.d/passwd (not poppassd, since I noticed after looking at the source file of poppassd that it ran the function pam_start with the parameter passwd). > cat /etc/pam.d/passwd password required /lib/security/pam_unix.so nullok md5 Then I telneted to port 106 (connected to poppassd) and I noticed it failed to work: telnet localhost 106 Trying 127.0.0.1... Connected to localhost Escape character is '^]'. 200 poppassd v1.8.1 hello, who are you? USER test 200 Your password please. PASS hello2you2 500 Old password is incorrect. Connection closed by foreign host. The username seemed to go trough, but the password was declined even though I am sure I have entered the correct password. I changed the source code a bit in hope to see where exactly the program failed and noticed that when popassd sent the password of my user test to PAM with the function pam_authenticate it didn't return 1 (for success) and naturally failed. After looking at the main log file of my machine all I could find in logs was this: Apr 22 14:05:21 gumb PAM-warn[2275]: service: passwd [on terminal: <unknown>] Apr 22 14:05:21 gumb PAM-warn[2275]: user: (uid=0) -> test [remote: ?nobody@?nowhere] Pretty much the same warning I got when trying the example program blank. Could someone please share some light on what my problem could be? Did I miss something, forgot to configure something perhaps?
