Hello, Apologize if this is the wrong place, but I know next to nothing about PAM and I'm not exactly sure where to ask this. Clue Bats graciously accepted. :-) I'm using PAM Md5 authentication (?) on SuSE Linux. I've installed popa3d <http://www.openwall.com/popa3d/> And I've instructed it to use AUTH_PAM in params.h /* * Choose the password authentication method your system uses: * * AUTH_PASSWD Use getpwnam(3) only, for *BSD or readable passwd; * AUTH_SHADOW Use shadow passwords directly (not via PAM); * AUTH_PAM Use PAM in the old-fashioned way; * AUTH_PAM_USERPASS Talk to pam_userpass via Linux-PAM binary prompts. * * Note that there's no built-in password aging support. */ #define AUTH_PASSWD 0 #define AUTH_SHADOW 0 #define AUTH_PAM 1 #define AUTH_PAM_USERPASS 0 First I used AUTH_MAN_USERPASS, but it failed, so I switched it to AUTH_PAM and it appeared to go just fine. I could pop and receive mail. Later I noticed this while tailing the log to make sure everything was OK: Nov 1 14:18:10 cla popa3d[15217]: connect from 123.456.789.10 (123.456.789.10) Nov 1 14:18:10 cla PAM-warn[15217]: service: popa3d [on terminal: <unknown>] Nov 1 14:18:10 cla PAM-warn[15217]: user: (uid=0) -> foo [remote: ?nobody@?nowhere] Nov 1 14:18:10 cla PAM-warn[15217]: service: popa3d [on terminal: <unknown>] Nov 1 14:18:10 cla PAM-warn[15217]: user: (uid=0) -> foo [remote: ?nobody@?nowhere] Nov 1 14:18:10 cla popa3d[15217]: Authentication passed for foo Nov 1 14:18:10 cla popa3d[15217]: 0 messages (0 bytes) loaded Nov 1 14:18:11 cla popa3d[15217]: 0 (0) deleted, 0 (0) left I've search the web and the PAM archives, but I can't find anything that resembles a solution. I've seen a lot of similar queries without any answers. :-\ I know this isn't tied to popa3d, so it has to be something I'm just not getting about PAM. As I said, I can authenticate and receive mail just fine, but I don't feel like it'd be a good idea to ignore those PAM warnings. Thank you for any help you can provide. -Brian
