Hi everyone, good morning.

Is only-one enabled on PPP/Profile configuration? If you use Radius server is Shared Users parameter set to 1?

Is active only one. I used radius server, but the parameter not set to 1.

Can you please clarify which RADIUS Attribute controls “Shared Users”

I find no reference to such an attribute in the wiki…

I have the same experience with multiple sessions being created despite the “Only One” box being checked for the PPP Profile assigned to my users who use external RADIUS.

This only occurs for users authenticating using external Radius. If I add users to local secrets the “Only One” parameter is respected.
