Lubuntu 14.04 samba 4.1.11, DC and 2 node cluster ctdb 2.5.3 Hi Problem: Non domain users are prompted twice for their passwords: stack at /etc/pam.d: auth sufficient pam_winbind.so auth [success=2 default=ignore] pam_unix.so nullok_secure auth requisite pam_deny.so auth required pam_permit.so auth optional pam_cap.so account sufficient pam_winbind.so account [success=1 new_authtok_reqd=done default=ignore] pam_unix.so account requisite pam_deny.so account required pam_permit.so account sufficient pam_localuser.so We have: ln -s /usr/local/samba/lib/libnss_winbind.so.2 /lib/libnss_winbind.so ln -s /lib/libnss_winbind.so /lib/libnss_winbind.so.2 sudo cp /usr/local/samba/lib/security/pam_winbind.so /lib/security The setup has worked OK 'till 4.1.11 although the pam winbind line was a guess which leads us to think this is a problem with the latest pam_winbind library. Could someone send us their working ubuntu or debian pam winbind or otherwise correct us? Cheers, Steve
