According to the spec, you can prompt the browser to allow the user to grant or deny browser notifications. Once the user has granted permission, is there a way to programmatically deny that permission too?
Calling window.Notification.requestPermission() after they have granted permission does nothing except run the success promise.
My goal is to have an On/Off button toggle in the user settings portion of my site. As far as i can tell, there is no way to toggle off once toggled on.
Unfortunately I don't think this is possible at the moment.
In the future we should hopefully be able to use the Permissions API to check and revoke notifications (as well as other APIs like geolocation etc).
However, while we can currently query the status of a permission, the revoke method is unsupported. I believe it was possible in Firefox until recently, but in 51 the functionality was changed to default to off.
As per MDN:
The revoke() function has been disabled by default starting in Firefox
51, since its design has been brought into question in the Web
Applications Security Working Group. It can be re-enabled by setting
the preference dom.permissions.revoke.enable to true.
Example of permissions API:
navigator.permissions.query({name:'notifications'}).then(function(result) {
console.log(result);
});
Result is prompt/denied/granted. Change 'query' to 'revoke' for denying permissions.
navigator.permissions.revoke({name:'notifications'});
Alternatively, this answer from a couple of years ago suggests an alternate approach which you might find interesting - using localStorage to approximate this functionality.

I'm trying to access user's presence off of https://learn.microsoft.com/en-us/graph/api/presence-get?view=graph-rest-1.0&tabs=http
I've granted my AD app Presence.ReadWrite.All which is described as "Allows the app to read all presence information and write activity and availability of all users in the directory without a signed-in user. Presence information includes activity, availability, status note, calendar out-of-office message, time zone and location.
".
There seems to be a bit of a conflict between the docs and what the permission's name is - the docs seem to imply it doesn't work with an application scope, while the permission name/description seems to say it does.
The error i'm getting is Forbidden. This seems to be different from accessing a resource with insufficient permissions (which straight up says InsufficientPermissions).
The docs are clear that you can't do this with Application scope. That means even if the particular permission seems like it should work, it might be because it's used in that way for another endpoint. Notice that, for instance setPresence and clearPresence both support Presence.ReadWrite.All.
What's really crazy though is that neither getPresence (your endpoint) nor (get Presence for Multiple Users)[https://learn.microsoft.com/en-us/graph/api/cloudcommunications-getpresencesbyuserid?view=graph-rest-1.0&tabs=http] support Presence.*Read*Write.All - there is no supported read scenario!
From what I can see, your best bet is to keep an eye on this request and to upvote it. Microsoft (Darrel Miller) is quite active there from last year - perhaps there's an update coming.
I have successfully installed liferay 7 and configured CAS 3.6 for SSO. Everything is working fine. I was able to create users, assign roles, create pages etc etc.
After few days, I was trying to create a new user via admin, I got warning "User 30810 is not allowed to access URL https://mysite:8443/group/control_panel/manage and portlet com_liferay_users_admin_web_portlet_UsersAdminPortlet". I could not able to create user. and from then that user does not have any permission that I use to do earlier.
I googled a lot on this, got few suggestions like
1) Adding below in portal-ext.properties:
redirect.url.security.mode=domain
redirect.url.domains.allowed=*.mysite.com
session.timeout.warning=0
session.timeout.auto.extend=true
2) Some links:
https://web.liferay.com/community/forums/-/message_boards/message/92226678
3) Somewhere it is mentioned that this it is bug with liferay started from liferay 7 GA4
4) If you read the link, it is mentioned that it related to Guest user and session expiration that starts causing this issue etc.
Had any one gone through this issue? Is there any solution or workaround for this?
I could not able to update this question with all the option I tried or solutions that is mentioned on google or liferay's official jira sites however I will keep updating this question with proper references.
Meanwhile
Do provide your suggestions/solutions.
"this starts happening when some session automatically logs out"
This phrase tells me several things, like the possibility of an user logging out even though you set "session.timeout.auto.extend".
Two basic scenarios where this can happen is:
When you close your tabs, after the assigned timeout, the user will be logged out. And when you got back, especially after a browser crash or using the back button, your browser used old data.
When you have the auto session extension working with a big timeout, leading to the possibility that the session timeout configured in Liferay being bigger than the one configured on the server.
On the last case, one might be interested on completed the config you exposed with short timeouts.
session.timeout.warning=0
session.timeout.auto.extend=true
session.timeout=5
session.timeout.redirect.on.expire=true
I know it is an old thread but it may help someone...
The "extend session" functionality is not working correctly and the final user session is expired, so when they try to log in, they have the wrong CSRF token from the previous session:
You have to double-check that the session.timeout Liferay portal.properties has the same value as the session timeout configured in your application server.
You have also check that the session.timeout.auto.extend.offset is greater than 60 seconds to avoid having problems with the chrome javascript intensive throttling
I'm working on an extension that's basically sending out an XHR request and parsing/displaying incoming XML. Ideally I'd like to let users enter the URL they want to send the request to, but to do this I believe I need to change the URL specified in the manifest.json every time the user enters a new URL. Are there any security concerns I should be aware of if implemented? If not I figure just setting the permission to *://*/* might be easier.
If you are letting the user select a URL, you have 2 approaches.
Just allow "<all_urls>" in the manifest (slightly stronger than "*://*/*"). Unless you're doing something specifically bad (like eval or exposing your internals using web_accessible_resources), the only security risk is yourself.
A fancy approach would be to use optional permissions. You put "<all_urls>" in optional permissions then request permissions for new hosts at runtime.
Pros: No scary dialog on install; give the power users comfort in knowing they provided only granular access.
Cons: A permission dialog will appear every time you need new permissions.
We plan to implement a company-internal portal with Liferay 6.2. Since many of the team members are not within the company's network, the access has to be allowed from the internet.
Now I see a big problem with the Guest role, since it 1) can access Guest-viewable content without login and 2) this is the default selection when for example uploading a document.
What I really need, is that only the login page is generally viewable, but all other sites and content is only visible to logged-in users, without the need to explicitely assign the permissions for each item correctly.
So the question is, can I prevent the guest role to access anything beyond the login page, so to say eliminate it from everything within the portal?
Update:
It was proposed to use only private pages. While this might work, it implies as far as I know, that each user has to be member of the site. But then it's no longer possible to have a site structure with different users participating in different sites and still be able to view public infomation (meaning public for all logged-in users) - or am I wrong?
Update 2:
I agree to a solution where one has to prevent the assignments to the guest role programmatically, via hook or via deeper changes in liferay. Yet, I like to double-check that administrative and think of a periodic database job or program using the API which check for relations to the guest role which came in around the hook or by wrong permission settings of a user and delete them again. How could that be done?
When a document is uploaded through a private page, the permissions actually default to be not accessible to "Guest". This is guaranteed easiest if you don't have any public pages.
Also, you can access the API and change the default permissions once a document gets uploaded (no need to override core Liferay functionality like defaults): Just write a service hook that overrides the upload of a document with a version that sets the permissions you want right after a document has been uploaded. This will catch all other upload attempts, e.g. through services, Webdav etc.
Edit (after your comment): Added the link to Dev Guide. The actual use of the API is a bit too much to update this answer with on the fly. You might want to look at old examples like sevencogs (part 2) to get used to the actual API, but DevGuide will describe how to write the plugin in the first place.
You could still use the public pages etc. and disable the guest's VIEW permission on every element but the login page and it's resources.
Now, as you have already noticed, the fact that, by default, whenever creating any content the Guest gets the VIEW permission is a substantial problem.
I'd suggest to simply override the <guest-defaults> values in Liferay's core portlets' resource permission files (the ones in ROOT/WEB-INF/classes/resource-actions/) to remove these default values. If it's not clear to you on how to do it, see, e.g., this forum topic: https://www.liferay.com/community/forums/-/message_boards/message/486154 .
All you need to do is delete all public pages. Every page that you create should be private. Don't worry about login page, reset password and self-registration (if allowed), by default they are public.
Hope this helps.
There is an application that we are using it both on XPiNC and browsers.
Before you can access the application, you must log-in with your user.id from lotus notes. The problem is there are several login msgboxes ( where you must again log in with your username and passwords ) saying:
The server says /xsp/.ibmxspres/dojoroot-1.8.1/dojo.
or
The server says /xsp/.ibmxspres/.mini/dojo/.en-us.
or
The server says /xsp/.ibmxspres/.mini/css.
or
The server says /xsp/.ibmxspres/.extlib/icons.
and so on. Even when I just hit F5 when I'm logged on in application ( there is, also, a computed field which displays the username ) those type of messages are being displayed.
What should I do as a developer? Or there must be some settings at the server?
I have the following ACL rights:
ACL: User type: Person and Access: Manager.
Effective access: all the checkboxes are checked except Full Access Administrator
Thanks for your time!
Ok, this should be straight out of the box ;-)
What I find strange is that the ressources you seem to be asked for access to use are some of the "built in" ressources (Dojo, css, etc.) in XPages...???
So first thing is really to test that this has nothing to do with your application:
Create a new application
Set a proper ACL that will force you to log in (Default reader or higher, a person called "Anonymous" no access)
Create a simple XPage and open it from the browser
What happens?
If everything works, then you need to add some elements that use the ressources (css, Dojo, etc.). Then what happens?
I guess you will see the same problems... If so, you need to have a look at the way you have set up your server for web access. Are you using internet sites? Do you use basic or session based authentication?
What does the ACL of your application look like?
What you experience could be caused by "realms" i.e. the "path" to which you log in. A simple example:
If you are required to log in to access the ressource /path/db.nsf/view/doc1?openDocument then your realm will be "/path/db.nsf/view/" - if then you try to create a document using /path/db.nsf/newDoc.xsp then you could be asked for access to the realm "/path/db.nsf/".
I must admit that I haven't seen these issues for quite a while - but that may be due to the fact that I control access to the database as a whole - if users need access to something inside the database I implement it using "public access". But first, let us hear a little more about your findings before we chase it as a realm issue ;-)
EDIT:
Ok, so you are using basic authentication. There are lots of good reasons to use session based authentication instead. However, that does not explain your problem. What OS are you using? An OS with file access in the file structure? Could it be that the user running Domino does not have access to the ressources? Have any (file) restrictions to these directories been set up? You really should not be prompted to login for these ressources....
Did you try another "new" application?
/John
Switch to session based authentication. The multiple prompts point to BASIC where you can't logout unless you close the browser
