    <description>&lt;P&gt;Hi all, &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I wonder if 1 username can restrict to only 1 session in VPN client.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Because i found that 1 username can authenticate and establish more than 1 session at one time and it's against my company rules.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I use ASA as the VPN remote termination and ACS as the aaa server.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Could anybody tell me what i should do? And i use the ACS for login in cisco device also. For cisco device, it has to be a multisession username.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thnx ^.^&lt;/P&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Yes. So long as RADIUS accounting is enabled you can use the ACS Max Sessions feature to restrict concurrent session usage.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;You can set max sessions limit against a user or group.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Darran&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
