Good morning, we had some issue tomorow's morning - some users couldn't login to an email system. We use ypages for distributing passwd maps, authorizing daemon is saslauthd. Some users logged in, some not. "Unauthorized" users made a record to the syslog: Nov 24 08:01:23 email1 saslauthd[10396]: DEBUG: auth_pam: pam_authenticate failed: User not known to the underlying authentication module Nov 24 08:01:23 email1 saslauthd[10396]: do_auth : auth failure: [user=username] [service=imap] [realm=] [mech=pam] [reason=PAM auth error] Nov 24 08:01:23 email1 imap[26411]: badlogin: localhost [127.0.0.1] plaintext username SASL(-13): authentication failure: checkpass failed About this time +/- seconds I see in the mail log this complains of the postfix to the cyrus's lmtp: Nov 24 08:01:25 email1 postfix/lmtp[29859]: warning: 19535581B: non-LMTP response from email1.fnhk.cz[public/lmtp]: do_ypcall: clnt_call: RPC: Timed out Nov 24 08:01:25 email1 postfix/lmtp[29859]: warning: to prevent loss of mail, turn off command pipelining for public/lmtp with the lmtp_discard_lhlo_keyword_address_maps parameter Nov 24 08:01:50 email1 postfix/lmtp[29859]: warning: 19535581B: non-LMTP response from email1.fnhk.cz[public/lmtp]: do_ypcall: clnt_call: RPC: Timed out Nov 24 08:01:50 email1 postfix/lmtp[29859]: warning: to prevent loss of mail, turn off command pipelining for public/lmtp with the lmtp_discard_lhlo_keyword_address_maps parameter The username was in all 3 hosts maps, another users logged in, there is no complains about network connections. This worked fine for an years, but this issue happened twice within 2 weeks. An administrators of the ypages servers don't see any problem or logs about theirs server. What caused this issue ? What can I do to prevent it. Thanks and best regards J.Karliak -- Ma domena pouziva zabezpeceni a kontrolu SPF (www.openspf.org) a DomainKeys/DKIM (s ADSP) a implementaci DMARC. Pokud mate problemy s dorucenim emailu, zacnete pouzivat metody overeni puvody emailu zminene vyse. Dekuji. My domain use SPF (www.openspf.org) and DomainKeys/DKIM (with ADSP) policy and implementation of the DMARC.
