Hi! i hope that the right address. my problem is: i'm using a freebsd-server with postfix and sasl > pam to authentificate users via smtp_auth over a windows-pdc from the syslog, i get the message: User "Michael" granted access, also all wbinfo-command work, my e-mail-programm says: 435 error: authentification failed my debug.log tells me: group, endgrent, not found Apr 20 18:34:57 bert postfix/smtpd[2525]: NSSWITCH(nss_method_lookup): file, hosts, gethostbyaddr, not found Apr 20 18:34:57 bert postfix/smtpd[2525]: NSSWITCH(nss_method_lookup): file, hosts, gethostbyname, not found Apr 20 18:34:57 bert saslauthd[639]: NSSWITCH(nss_method_lookup): winbind, passwd, getpwnam_r, not found Apr 20 18:34:57 bert saslauthd[639]: NSSWITCH(nss_method_lookup): winbind, passwd, getpwnam_r, not found Apr 20 18:34:57 bert saslauthd[639]: DEBUG: auth_pam: pam_authenticate failed: authentication error Apr 20 18:35:00 bert cron[2528]: NSSWITCH(nss_method_lookup): winbind, group, setgrent, not found Apr 20 18:35:00 bert cron[2528]: NSSWITCH(nss_method_lookup): winbind, group, getgrent_r, not found Apr 20 18:35:00 bert cron[2528]: NSSWITCH(nss_method_lookup): winbind, group, endgrent, not found Apr 20 18:35:00 bert cron[2528]: NSSWITCH(nss_method_lookup): winbind, passwd, endpwent, not found Apr 20 18:35:22 bert -su: NSSWITCH(nss_method_lookup): winbind, passwd, endpwent, not found and maillog: Apr 20 18:34:57 bert postfix/smtpd[2525]: smtpd_sasl_authenticate: decoded response: michael Apr 20 18:34:57 bert postfix/smtpd[2525]: smtpd_sasl_authenticate: uncoded challenge: Password: Apr 20 18:34:57 bert postfix/smtpd[2525]: > ernie.bio2.RWTH-Aachen.DE[134.130.63.5]: 334 UGFzc3dvcmQ6 Apr 20 18:34:57 bert postfix/smtpd[2525]: < ernie.bio2.RWTH-Aachen.DE[134.130.63.5]: UjZvYTBmSENUSlBvaA=Apr 20 18:34:57 bert postfix/smtpd[2525]: smtpd_sasl_authenticate: decoded response: $passwort Apr 20 18:34:57 bert postfix/smtpd[2525]: warning: ernie.bio2.RWTH-Aachen.DE[134.130.63.5]: SASL LOGIN authentication failed Apr 20 18:34:57 bert postfix/smtpd[2525]: > ernie.bio2.RWTH-Aachen.DE[134.130.63.5]: 435 Error: authentication failed Apr 20 18:34:58 bert postfix/smtpd[2525]: watchdog_pat: 0x247288 Apr 20 18:35:03 bert postfix/smtpd[2525]: smtp_get: EOF Apr 20 18:35:03 bert postfix/smtpd[2525]: lost connection after AUTH from ernie.bio2.RWTH-Aachen.DE[134.130.63.5] Apr 20 18:35:03 bert postfix/smtpd[2525]: disconnect from ernie.bio2.RWTH-Aachen.DE[134.130.63.5] Apr 20 18:35:03 bert postfix/smtpd[2525]: master_notify: status 1 my configuration is sasl2/smtp.conf : pwcheck_method: saslauthd mech_list: PLAIN LOGIN CRAM_MD5 DIGEST_MD5 log_level: 6 smb.conf: [global] workgroup = Biologie2 netbios name = bert server string = bert security = DOMAIN log file = /var/log/samba/log.%m max log size = 50 load printers = No os level = 20 interfaces = dc0 bind interfaces only = yes winbind uid = 10000-20000 winbind cache time = 10 template shell = /bin/bash template homedir = winbind gid = 10000-20000 winbind use default domain = yes winbind separator = + winbind enum users = Yes winbind enum groups = Yes nt acl support = Yes password server = avifauna encrypt passwords = yes socket options = TCP_NODELAY local master = no domain master = no preferred master = no [www] comment = HTTP-Server path = /usr/local/www/data-dist valid users = Administrator public = no writeable = yes printable = no create mask = 0655 /pam.d/smtpd: account sufficient pam_winbind.so debug (tried other settings but made no difference) i also compiled postfix with sasl2-support and smb with nss and started saslauthd -a pam the same works with pam_unix.so so the problem must be the winbind-module how i have no idea how i can solve that problem, i pray for help!
