Limit number of concurrent session per client

[Nicolas Micoud]

Hi,

I would like to limit the number of concurrent session per client (AD_Client).

An iDempiere instance has several clients.

And I would like that client 1 can use 5 sessions at a time ; client 2 10 sessions, ...

My idea is to add a field "set as Advanced" on AD_Client : "Number of concurrent session".

And if it is filled, on the login page, compare it with the active session and proceed or show a message ("you have reached the limit !").

Note that some users should be allowed to connect, whatever the number of session (System, SuperUser and ClientAdmin for instance). That would be done in a new table or via a new checkbox on AD_User.

Do you think that could be a common requirement ?

Regards,

Nicolas

With this, I think add more option. one account only active on one concurrent session.

also add if a ad_user is not allowed for more than 1 session ( like for production ) 

[Carlos Antonio Ruiz Gomez]

This sounds useful for a SaaS business, and also for performance reasons in some normal installations.

But I think the rules will tend to be very flexible - would it be better to create an extension like "MultiSessionControl"?

Hi Nicolas,

have you thought about using a model validator for this? There is the login(Client, Role, User) method where you could return an error if the maximum user count is reached. To keep count of logged in users, you could use the MSession po i think. I believe you could implement all this in your own plugin without modifying the core.

[Pedro Rozo]

That is a very common requirement .. hope you can publish the plug-in if it is not integrated to the core to test it.

Hi,

The plugin is available here : https://bitbucket.org/nmicoud/org.tgi.limit-concurrent-session

What is added :

 - AD_Client.IsLimitConcurrentSessions : to activate the functionnality

 - AD_Client.MaxConcurrentSessions : maximum sessions for the current client

 - AD_Client.ConcurrentSessionsMsg_ID : message displayed when user can't login

 - AD_User, AD_Role, AD_Org : IsDontCountMeInConcurrSessions : allow to set the record to be not taken in consideration for checking limit of concurrent sessions

 

How does it works ?

After the user is logged, the plugin checks if the maximum number of session is reached (using IEventTopics.AFTER_LOGIN).

If yes, a message is displayed and the user returns to the login page.

I haven't tested for a long time, but it seems to do the job.

Feel free to test it and give feedback.

Thanks

Nicolas

Hi Nicolas....

A quick message to let you know that your plug-in is working good, just want to report that after the deployment (packin) .. it is required: 1. restart the server (otehrwise we get wird errors with postgres perhaps due to AD changes not processed)

2. To test the plug-in we need to go to all the organizations, roles and users  to disable the checkbox:  .Don't count me in concurrent sessions

3. Enable the feature within the client window:  Limit number of concurrent sessions   ans set max session and error message.

Thanks for your controibution, and receive our apologies for the delay with these tests but we did not check the progress if this thread since the last year.

Regards,

Pedro Rozo.

Thanks for the feedback, i've updated the wiki.

Nicolas

Hi every One.

I tryed to run plug in, i compiled, exported and installed but when i go to client window i cant see the check Limit number of concurrent sessions.

Please maybe my way to export is bad, can help me with this.

Regards.

Hi Alfredo,

Maybe you can't imported  the pack out....or if you has made changes to yours windows, maybe you need to enable the new options.

Regards

Hi Nicolas,

Can you update the repo ??

Thank in advance 

Regards, 

[Nicolas Micoud]

Hi Alejandro,

I'm not using it anymore, that's why I guess I did not migrate it to github.
Anyway, I've attached a zip file that contains sources.
As is just an event, it should work directly in newer iDempiere versions.

I'm quite busy ATM, but adding to the TODO list to upload it on github.
If you find things to improve, tell me.

Regards,

Nicolas
