I have the same problem, though I don't have any unix_chkpwd errors as it's not installed on my systems.
I was able to solve it by replacing: 1) libpam-ldap by libpam-ldapd 2) libnss-ldap by libnss-ldapd 3) nscd by nslcd I think it is related to my use of self signed certificates that libpam- ldap has trouble handling. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1314095 Title: Unity Lockscreen in 14.04 can't unlock when using LDAP account To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1314095/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
