Forum Problems Installing LAMS: Re: Re: Re: Re: LAMS and sakai integration problem

I changed the URL as suggested by you but no luck.

I am getting following message in a popup when i click "open author".

--------------

HTTP Status 502 - Login Failed - failed to fetch user info from the third party server

type Status report

message Login Failed - failed to fetch user info from the third party server

description This server received an invalid response from a server it consulted when acting as a proxy or gateway (Login Failed - failed to fetch user info from the third party server).

I hope this helps!

I think we are one step closer to solving this.

The user information url is correct. When lams is retrieving the user info from the sakai server, it is getting a 502 error.

Could you please post both the sakai and lams logs.

Also, depending on what time zone you are in, you may be able to contact me via Skype. I am located in Sydney, Australia (GMT+10).

Thanks for the help. The problem got solved when i did fresh
build from the source code. Now the problem is solved for authentication but system is behaving differently.

To replicate the behaviour, please log into sakai and do following things.
1. Create a new account.
1. Log in as admin and allow access to LAMS for the new user.
2. log in as new user and access the LAMS link from left menu of sakai.
3. Access "New lesson" on LAMS screen. The system will display the workspace along with option to author.
4. Access "open author" screen that will open authoring window of LAMS in new window. Now close the window without creating any activities.
5. Accessed "open author" screen again but now the popup window shows "page not found".
6. Surprisingly when servers are restarted both Jboss and tomcat (sakai), it worked for the first time but for the second time it again showed page not found.

There are no errors displayed on both the consoles.

Could you please help us on this.

Can I clarify one thing.

If you open the author screen, close the browser altogether (ie quit Firefox, IE, etc), open the browser and log in again, do you get the authoring window or the "page not found".

When you call LAMS the first time in a session, it has to do some extra work to log you into LAMS. That may be why we are seeing a difference between the first and second time. Restarting the browser will test this.

A small correction in the steps mentioned in earlier post. Please note step 5 below.

1. Create a new account.
1. Log in as admin and allow access to LAMS for the new user.
2. log in as new user and access the LAMS link from left menu of sakai.
3. Access "New lesson" on LAMS screen. The system will display the workspace along with option to author.
4. Access "open author" screen that will open authoring window of LAMS in new window. Now close the window without creating any activities.
5. Logout and log back in. Repeat the above steps from 1 to 3.
5. Access "open author" screen again but now the popup window shows "page not found".
6. After i close the window as suggested by you and log back in on a new browser. It works. But it doesnt work if i logout and log back in the same browser instance.

We haven't been able to replicate this problem at all. Not using the Sakai-LAMS Demo server nor by reinstalling Sakai and LAMS from scratch again and following your instructions meticulously.

But don't take my word for it, you can try doing this in the Sakai LAMS demo site. When the "page not found" appears, what's on the LAMS logs?
