Post subject:  Proposed Solution: Double Login Issues
Hi everyone,

there are quite a few users who are experiencing problems upon their first frontend login, however, the login works the second time for most of them. The corresponding threads are at least these:
http://forum.joomla.org/index.php/topic,76935.0.html
http://forum.joomla.org/index.php/topic,92425.0.html
http://forum.joomla.org/index.php/topic,67290.0.html
http://forum.joomla.org/index.php/topic,87929.0.html
http://forum.joomla.org/index.php/topic,72398.0.html
http://forum.joomla.org/index.php/topic,71369.0.html

I believe that most of these issues occur for users visiting your page from a URL other than the livesite URL set in your global config. Lets imagine your livesite URL is http://www.example.com, but a user visits you under example.com. Indeed, there is no possibility for this user to login on the first attempt. Now, if you encounter such problems, you might be lucky, as some (if not all) these issues have been identified.

If you are willing to test this proposed solution, please follow these steps. But before you start, keep in mind that all such changes could as well break your site, so I wouldn't use it on a production system, but rather only on a test system.
  • Use the attached files only on Joomla! 1.0.11. They are not compatible with other versions!
  • Make a backup of the files /includes/joomla.php and /modules/mod_login.php first.
  • Download the zip-file which is attached to this post, und unzip it to a temporary location.
  • Overwrite /includes/joomla.php with joomla.php.
  • Overwrite /modules/mod_login.php with mod_login.php.
  • If you have set a value for the "Login Redirection URL" for the login module, please delete it or make sure the domain matches the domain you use as your live_site in global configuration.
  • Please report back if you are still experiencing any login issues.

As said, I would never use any patches directly on a production server, so use them only on a testing server or know what you are doing :)

Looking forward to your feedback,
Enno

This works Lekker!

Nice - IE and FireFox both login , both on http:// and http://www and first time too.

Installed brand new site , and there was this login problem , then put patch , and perfect!

I then put it on my live site , and it worked perfectly.

Now I have a suggestion : Go get a few beers and celebrate. I now have 12 sites that have login capability!

Seriously....Paypal Address? Send me email.....

What about adding the following to the configuration.php file? I've found that this fixes the whole issue of sites being accessed from http://www.domain.com or domain.com.
Code:
$mosConfig_live_site = 'http://' . $_SERVER['HTTP_HOST'];

Thank You once again.

Hello all,

I never had this problem, but I am doing something that will also fix this, by adding the following to my .htaccess :
Code:
RewriteCond %{HTTP_HOST} ^mydomain\.com [NC]
RewriteRule (.*) http://www.mydomain.com/$1 [R=301,L,NC]

every request form mydomain.com/xxxx is redirected to http://www.mydomain.com/xxxx, through a permanent redirection (you can do it the other way around if you like of course, from www to non-www).

The big advantage (that was the reason to do it in the first place) is to avoid duplicate-content penalties in search engines, as your site is going to be indexed twice. if you do not do something like that mydomain.com/mypage.html and http://www.mydomain.com/mypage.html will have same content on the same domain, but differing sub-domain and URL.

So the .htaccess the safest method? I've placed the code into my .htaccess file, but its not working. Does something need to be removed, or do these lines need to be in a specific place?  Sorry for the confusion. I'm new to this.

Post subject:  Re: Proposed Solution: Double Login Issues
Still getting the same issue after applying this patch on my Joomla site running under IIS (so I can't use .htaccess method).

The only fix I can find that works is either ticking the remember me box or checking the login message parameter on the login module which says "You are now logged in". These work - but aren't great solutions !

Have tried removing my login redirection, tried the attached files, tried the other '0' session fix - but still not working as it was before  :(

Joomla! 1.5 is doing something quite similiar - no mosConfig_live_site anymore. I doubt it though that this will change for 1.0.x - it changes behavior, and is probably out of scope of a stability release. I can also see one problem arise from this change: let's imagine your users log in on http://www.example.com. Now lets assume you have a hardcoded Link in your content to example.com/index.php?whatever. The user logged in on http://www.example.com, and will be treated as a guest on example.com - this would just create one new instance where a user might think he got logged out. That's why I'm not in favour of adjusting the livesite dynamically in 1.0.x. I'd rather get the login issues fixed, and leave the livesite settings alone (except for the https switchover which will probably make it into 1.0.12).

Maybe I am just very consistent in my hard coded links, but I haven't noticed this problem.

Interesting find, the thing about the login message.

I don't have access to IIS, and found out that it's not within the MSDN Academic Alliance, from where I thought I could get it.
I'll take a look at it this weekend and ask some of the other devs to test this on IIS. I've seen some interesting posts about redirection, cookies and IIS somewhere, just need to digg it up ;)
Author:  davemacd [ Wed Oct 25, 2006 8:50 pm ]
Post subject:  Re: Proposed Solution: Double Login Issues
Thanks, much appreciated.

For now I am using the login message and it's working round the problem so no massive hurry  ;)

That's a good thing. I never write the domain name into the links, but have the SEF-URL-Mambot run on it, so that it will use the live_site when converting the link to the SEF-version.

Try this to simulate the bahviour I'm describing:
Clear all cookies, log in on http://www.yourdomain.com, and go to yourdomain.com afterwards. You should find out that Joomla! treats you as a guest...

livesite setting needs to stay in 1.0.12, agreeing.

i would rather have joomla redirecting to the correct site automatically in case of an alias site than removing the livesite.

That's absolutely normal: for cookies, these are two different sites, and browsers don't allow cookies to spread.

Thus, the only cure is redirecting in case of wrong site, either in the dot htacceess file or in joomla itself ;)

Ok..go slow for a newbie. 

From what I can gather from this thread, there are 3 proposed solutions to the issue. 

- Overwriting the files as in the original post by friesengeist
- changing .htaccess as suggested by shumisha
- changing the configuration.php as suggested by unixboymd.

Is there any kind of consensus?  ???

I've been using Joomla for all of about a month or so and reading some of these threads can get kind of confusing!  :-[
Author:  TheWagner [ Thu Oct 26, 2006 1:50 pm ]
Post subject:  Re: Proposed Solution: Double Login Issues
Agreed. I'm still  lost on the best solution and I can't get the dot htaccess change to solve the problem.
I added the code, and when I go to domain.com it does not automatically take me to http://www.mydomain.com.

All three are valid, let me try to explain the differences:
  • The initial post of this thread is meant for getting feedback from users, if it solves all know login issues. So far, I'm satisfied with the results, only Microsoft's Internet Information Server (IIS) still has problems. So something quite similiar to this will probably be used in 1.0.12, I'll discuss some details with Beat in the next days.
  • Changing .htaccess will not work on every server, as a special module (mod_rewrite) needs to be loaded by the server. I have no clue how this would look like in IIS, but I doubt it that you can use a .htaccess (written for Apache) on IIS. So this is indeed a good solution, but not really within the scope of Joomla!, as it depends to much on your server config. However, this avoids penalties for duplicate content from search engines, as your content can only be found under one doamin - so it's basically a good thing.
  • Changing the configuration.php (or achieving the same thing in any other file) is IMHO out of scope for 1.0.12, as stated earlier by me.

So it's your choice, use what ever solves the issues for you :)

BTW, thanks to everyone who tested the patch! Let me hear if there is anyone for whom this is not working (except for IIS).

Upgrading to the latest and greatest release of Joomla not only fixes bugs but also helps keep your site secure.

To reinforce Enno's last post. 

This topic of this thread is on feedback for the proposed solution.  Let's stay on this topic please.

Thanks.

That's a different issue, but it is okay if you log in as one or the other since the above solution solves the javascript problems that come from www v. non www.
