Allow only one loggin for same username on SSL VPN

[Plima]

Hi Everyone,

I have a user group where I only want to allow one session by user. In other words, if the user ABC is logged on the VPN Client and other user log in with the same user (ABC) the result will be denied. I want this for all users in the firewall group.

Is that possible?

thanks

This seems to be the same conversation.

You can set that in the ssl setting to the number of concurrent  vpn users. IIRC it works like this, 

1: User TEST logins 

2: now user TEST attempts to login in , the firewall warns this to this new request with the action to disconnect the 1st user TEST session

Is it the same fortigate  for the two logins? Did you run any diag debug app sslvpn -1 and monitor what the firewall thinks

Hi Ken,

Is the same Fgt. Yes I run the debug and don't spot anything unusual.

The user came from LDAP, is that relevant?

Thanks

 Yes, under the SSL-VPN Portal select your portal and enable the "Limit Users to One SSL-VPN Connection at a Time" option. You could use the CLI command too:

FGT# config vpn ssl web portal FGT (portal) # edit web-access  <-- Portal name FGT (web-access) # set limit-user-logins enable

Hope it helps!

This configuration can also be used for tunel mode.

FGT01 (full-access) # show config vpn ssl web portal     edit "full-access"         set tunnel-mode enable         set web-mode enable         set limit-user-logins enable         set ip-pools "SSLVPN_TUNNEL_ADDR1"         set split-tunneling-routing-address "DMZ" "LAN"         config bookmark-group             edit "gui-bookmarks"             next         end         set theme green     next end FGT01 (full-access) # [style="background-color: #ffff00;"]set limit-user-logins[/style] [style="background-color: #ffff00;"]enable[/style]     Enable setting. disable    Disable setting.

limit-user-logins                     Enable to limit each user to one SSL-VPN session at a time.
