Theme: `pam_unix.so` makes the login screen blank #544

msp1kpj · 2016-09-01T22:57:07Z

Bug report for authentic-theme 18.10 on Webmin 1.810 on CentOS 7.

When Webmin is configured NOT to use "pam_unix.so" in "/etc/pam.d/webmin" and instead uses the system's sssd configuration via "include system-auth" for all "auth/account/session" entries, the login screen is blank.

The following errors show up in the console log for both Firefox 47.0.1 and Chrome 52.0.2743.116:

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

Hi,

I will try to reproduce this issue and fix it in the near future.

Thanks for reporting.

iliajie · 2016-09-02T07:53:02Z

Just to double-check - if you change to Gray Theme you don't see such issue? Because if you do, it's Webmin bug.

msp1kpj · 2016-09-06T12:44:20Z

That is correct. If we switch to the Gray theme the sign in works correctly.

iliajie · 2016-09-06T12:48:38Z

Is there a way you could post a screenshot of how it looks like when error comes?

msp1kpj · 2016-09-06T13:05:28Z

I can. But all or come back with is a Grey screen. Is there something else that would help more? There are JavaScript Errors, about "NProgress is not defined"

iliajie · 2016-09-06T13:07:02Z

Ah, ok.

What is the page's URL of the right frame? Look at the source of the iFrame to find out.

msp1kpj · 2016-09-06T13:18:23Z

Here is the source code to "/session_login.cgi?logout=1", I could not find an iframe in the html source

iliajie · 2016-09-06T13:19:44Z

Alright, I will take a look. Thanks.

msp1kpj · 2016-09-06T13:21:37Z

It looks like the HTML is there but the JavaScript Exception is not allowing the Opacity on the "body:not(.csf):not(.e) .container-fluid " to be set to 1

iliajie · 2016-09-06T13:30:40Z

Add the following to the /etc/webmin/authentic-theme/styles.css

body:not(.csf):not(.__e__) .container-fluid {
    pointer-events: auto;
    opacity: 0;
}

msp1kpj · 2016-09-06T14:12:47Z

This path does not exist on our CentOS box. Is this a new directory or is there another path I should use?

msp1kpj · 2016-09-06T14:14:56Z

I found "/usr/libexec/webmin/authentic-theme/". Would that be the correct path?

iliajie · 2016-09-06T14:19:55Z

No. /etc/webmin/authentic-theme - create it!

msp1kpj · 2016-09-06T14:42:39Z

I am not seeing that file being loaded in. I create a similar fill in the


<link href="/webmin/unauthenticated/css/bootstrap.min.css?1810" rel="stylesheet" type="text/css">
<link href="/webmin/unauthenticated/css/bootstrap.tagsinput.min.css?1810" rel="stylesheet" type="text/css">

But I added a similar file in the "/usr/libexec/webmin/authentic-theme/unauthenticated/css/styles.css" directory and it is showing.

<link href="/webmin/unauthenticated/css/bootstrap.min.css?1810" rel="stylesheet" type="text/css">

I change the CSS to opacity 1. Is is showing the page now but the "Continue" Button does not submit the form.

body:not(.csf):not(.__e__) .container-fluid {
    pointer-events: auto;
    opacity: 1;
}

msp1kpj · 2016-09-06T14:52:38Z

When doing the AJAX request for"/index.cgi/?xhr-get_theme_language=1" and "/index.cgi/?xhr-get_available_modules=1" it is bring up the "Login to Webmin" page.

iliajie · 2016-09-06T15:02:34Z

I got the reason why. I might come back a bit later with a question, otherwise I'll just fix it upon next release.

msp1kpj · 2016-09-06T15:09:21Z

OK, Let me know if you need an further testing.

iliajie · 2016-10-23T12:21:12Z

What is your /etc/pam.d/webmin content?

iliajie · 2016-10-23T12:35:51Z

..I'm trying to reproduce it.

iliajie · 2016-10-23T13:22:30Z

If you run in the console __s___(); will it work?

iliajie · 2016-10-29T15:02:19Z

After 18.20 release please double check. It might be working fine. In case it doesn't PLEASE reopen this issue and will try again. I think, I fixed it (theoretially) but I don't know how to make pam_unix.so setup work quickly on my system.

In case it's not fixed, please reopen the issue and tell me how to set things up.

18.20 will be release very soon.

iliajie · 2016-10-29T20:32:32Z

Version 18.20 is out, please upgrade.

iliajie · 2016-11-25T18:38:45Z

I could finally reproduce it and I found out that the login screen in Authentic Theme didn't even consider PAM auth.

#580

It will be working as expected in 18.30.

Why are you using PAM auth, by the way? Why not using default one?
