openkm custom logout

[tintin_chan]

Hi All,

Is there any way I can manipulate the File -> Exit behaviour on the main page? I have tried modifying the logout.jsp in the admin folder to redirect to somewhere but it does not seem to be working.

Any advice is welcome. Thank you.

[jllort]

Why do you want to forward to other url ? It's hard coded in class LogoutPopup.java

Code: Select all

public void onClick(ClickEvent event) {
		super.hide();
		Window.open("index.jsp", "_self", null);
	}

Hi,

My authentication is CAS. I need to perform a logout on the CAS server. Is this the only way to do it?

[tintin_chan]

I have replaced the original LogoutPopup class but when I click the exit submenu, it is not directing to the intended URL. Is there anything to do with the cache?

[tintin_chan]

What I do not understand is when i purposely remove the LogoutPopup.class in WEB-INF/classes, the app runs fine. However when i delete the XXX.cache.html in com.openkm.frontend.Main folder, the app is unable to run. Am i missing something here? Thanks.

NO NO NO that's a GWT class and must be compiled all project to generate javascript. Changing class file will not have any effect on javascript generated by GWT ( the ui is generated by GWT ).

Hi jllort,

I have recompiled the source code for gwt using maven command "mvn gwt:compile -Dgwt.module=com.openkm.frontend.Main" and I am able to redirect to the URL I wanted. However when I click the back button of the browser, I am still logged into OpenKM main page. How do I completely clear the session data before the redirection to the URL takes place? Hope you can enlighten me. Thank you

[jllort]

You're not logged sure, because the RPC call is for kill session, but when you're pressing the back browser button you're seeing the browser cache nothing else ( if you try click on some resource will appearing a lot of errors ). You might investigate if there's some way to clean the browser historic with javascript.

Hi jllort,

Thanks for your time in replying. What I mean is when I click the back button, I am still able to perform stuff on the main page e.g delete a document with no error. It seems to me I am not logged out at all.

I ever tried redirecting to a custom jsp page and call session.invalidate() before redirecting to the CAS server. However I am still able to perform stuff on the main page.

Do you have any more ideas for me on the above scenario?

[jllort]

Before redirecting ( GWT ) there's a RPC call to logout, that must be done, after it you can forward to other page, ensure this call is still done.

Hi Jllort,

I have called logout() function in LogoutPopup.java before directing but I have encountered the following error "ERROR [com.openkm.frontend.server.OKMAuthServlet] CallbackHandler does not support: javax.security.auth.callback.NameCallback@52250" below:

May I know if I am missing something on my side?

[jllort]

Are you executing logout twice ?

[tintin_chan]

Hi jllort,

I am unsure when the logout() in LogoutPopup.java is invoked but I have reused the logout() before redirecting. Hence I am unsure if I have performed logout twice by doing this.

[pavila]

If you want OpenKM to be integrated with CAS, you should send us the proper JBoss / OpenKM CAS configuration and we will include this in the next major release.

[jllort]

add some log in logout method ( AuthServlet ) and you'll see it. TAke a look at server.log I'm not sure, but all methods have log.debug might be there one time or more.
