How to set different inactivity and Max session timeouts for the users in the different AD group

Thanks for the quick reply , let me try this and come back ,.... if i have multiple AD-group/clients which needs different timeout settings , then the irule will look like this:-

when ACCESS_POLICY_AGENT_EVENT { 
if { [ACCESS::policy agent_id1] eq "set_timeout_values" } {
    switch -glob [ACCESS::session data get "session.ad.last.attr.memberof"] {
        "*CN=Standard_SSL_Users*" {
            ACCESS::session data set session.inactivity_timeout 150 
            ACCESS::session data set session.max_session_timeout 200
            log local0.notice "Inactivity and Max timeout set" 
        }

if { [ACCESS::policy agent_id2] eq "set_timeout_values" } {
    switch -glob [ACCESS::session data get "session.ad.last.attr.memberof"] {
        "*CN= SSL_Users2*" {
            ACCESS::session data set session.inactivity_timeout 600 
            ACCESS::session data set session.max_session_timeout 200
            log local0.notice "Inactivity and Max timeout set" 
        }

if { [ACCESS::policy agent_id3] eq "set_timeout_values" } {
    switch -glob [ACCESS::session data get "session.ad.last.attr.memberof"] {
        "*CN= SSL_Users3*" {
            ACCESS::session data set session.inactivity_timeout 600 
            ACCESS::session data set session.max_session_timeout 200
            log local0.notice "Inactivity and Max timeout set" 
        }   

    } } } } } } }
