Sorry for the late reply, Firstly, I'm not sure I'm seeing the same thing as Peter. I haven't had any other application ask for the password twice (e.g. any of the 'unlock' buttons in GNOME, or gksu[do]).
Secondly, here are the non-comment lines from my /etc/pam.d/common-auth: auth [success=1 default=ignore] pam_unix.so nullok_secure auth requisite pam_deny.so auth required pam_permit.so auth optional pam_smbpass.so migrate -- GDM asks for password twice during login https://bugs.launchpad.net/bugs/262910 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
