No login possible when using a directory (e.g. active directory via sssd)

[Fuchs]

SDDM in the default (and only provided) theme doesn't allow a custom username to be entered.
Unfortunately it also only shows local users, thus when you have your machine in some sort of directory (LDAP / Active directory as an example), it is impossible to log in.

The default theme has to provide a method to enter a user name manually, else in set-ups such as enterprises or universities, where no local users are created and just directories are used, sddm is completely unusable.
Therefore I recommend a very high severity for this bug.

Also see https://bugzilla.redhat.com/show_bug.cgi?id=1007067 (they now offer a custom username field)

Version: Ubuntu Vivid
Packages: sddm 0.11.0-0ubuntu10 / sddm-theme-breeze 4:5.2.2-0ubuntu3: amd64 i386

What I expected to happen: After upgrading to Vivid I expected to be able to log in
What happened instead: I was not able to log in

How this should be fixed: either switch to a different default theme which does offer a username field or edit the default theme to offer it optionally.

Status changed to 'Confirmed' because the bug affects multiple users.

Any news on this bug (filed last year)? This is a showstopper for anyone not using linux on a hobbyist basis where every username is stored locally in /etc/passwd and not in some centralized ldap db.–or made available via sssd, which certainly is more common in a work/corporate env.

This appears to be a matter of installing the 'correct' theme (although I strongly believe this should be offered regardless of which theme is being used as it is basic functionality, and certainly should work by default.)
