Can you use the page-down and arrow keys to navigate the list? Which Display Manager ( [kxg]dm ) are you using? Try a different one if the keyboard navigation does not work.

This, in fact, *is* the correct answer. That it’s enabled is bad.
1. Security. Having the username, which someone being nasty wants to
break into, but doesn’t know it, this is just that much easier.
2. You have over 100 users. That’s annoying to scroll through. Certainly,
each user *ought* to know their own username, and it’s faster to
type it in, than scroll down 5 or so names at a time through 100+.

Good point. I never liked the user list anyway. Wonder why the RHEL 7
designers chose to add it?
/Ole
Likely because it is in Fedora and they did not take it out, and it is likely the default from the GNOME project as well.
To each, their own preference.
Pretty sure that Alan filed a bug against RH with this, but, as RH seems to do these days when sysadmins complain about Fedora-isms, it was probably ignored.
Merrily trolling,
A request to disable the user list filed against RHEL-6 was ‘denied’:
Kind of crazy that the reason fixing it was denied was that they wouldn’t change behavior mid-revision in 6.x. And now it is still not fixed in 7.x, and a mid-rev change actually breaks things even more.
I was showing my post to people at work, so I’ll make sure they see it. :)
Aside from the annoyance of having all local users listed on the login screen we have noticed with CentOS7 using NIS and NFS home directories that once a user authenticates their home directory is automatically mounted on boot, even after rebooting and disabling the list using
is this a separate issue with our NFS server or is this related to the userlist?
thanks

frankly, this blows my mind. not long ago there was a huge kerfuffle over the change to only allow (as someone defined it ‘secure’) certain passwords, requiring numbers, special characters, some minimum length and that -had to be done- because people didn’t use proper passwords and couldn’t be trusted to just use what was appropriate/correct for their environment.
now a completely reverse the position, plain text showing user names to the world (which has always been considered to be poor security at best)
is just ‘yeah, whatever you feel like doing. go ahead.’
User interface decisions are never driven by security. If security is mentioned then it is used as a fig-leaf to shut down dissent.
Security when applied to these sorts of decisions is the patriotism of the FOSS world. The last refuge of scoundrels who have no desire to admit error and wish no discomfort from making any.
The actual reasons for change usually come down to the aesthetic values of a small group of developers, or often a single individual, with the power to impose their vision on the rest of humanity. And the desire to do so. I cannot imagine why. . .
Seems RH, intoxicated by Fedora’s wildest screwballs, has started to loose its purpose and its sense of direction. The constant problems with C7 updates is a nightmare for some dedicated CentOS fans.
This is just absurd.
Fedora and Red Hat are just using Gnome’s default settings for the user list. Red Hat even documents how to change it. I’d hardly call this some sort of ‘loss of direction’. A distro makes choices and if you disagree with them, that doesn’t always mean that they’re screwballs.
Constant problem? You mean the first point release? I agree that there have been problems, but I’m not seeing a nightmare for most people. A lot of bugs are being shaken out from the initial release, so I’m not terribly surprised to see significant changes introduced in 7.1503.

This is an upstream bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1184802
Great, thanks for the info! Now we just need a bug fix :-)
/Ole
No, page up/down and arrows don’t work either.
Display Manager: Whatever comes with CentOS 7.1 (cannot be changed at the login screen).
Johnny Hughes informed us that an upstream bug has been reported:
https://bugzilla.redhat.com/show_bug.cgi?id84802
/Ole
I mentioned two other workarounds myself. I prefer to wait for the upstream bug to be solved:

So, it’s not going to change…
