With regard to Bug #856269 , which is marked as duplicate of this one, I have found that when the password of a domain user is expired, lightdm still does not present the correct steps to change the password. Here is what happens (lightdm messages are inside ""):
1 - "" --> ******** (first enter expired password); 2 - "(current) NT password" --> ******** (expired password) 3 - "Retype new NT password" --> ******** (new password) 4 - "Invalid password, please try again" There is a step missing between 2 and 3, and it should be "Enter new NT password". Also lightdm should display, before step 2, a message saying that the password is expired and need to be changed. Using su in a text console to login, the correct password changing dialog is presented: renzo@vmo-amb20:~$ su rbag Password: You need to change your password now Changing password for rbag (current) NT password: Enter new NT password: Retype new NT password: rbag@vmo-amb20:/home/renzo$ Should I report a new bug? ** Attachment added: "lightdm_pam-samba_configurations.tgz" https://bugs.launchpad.net/lightdm/+bug/851347/+attachment/2506895/+files/lightdm_pam-samba_configurations.tgz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/851347 Title: pam_group not working at all To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/851347/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
