Problems comparing memberof variable

Try this one:

when ACCESS_ACL_ALLOWED {
    set aux "[ACCESS::session data get session.ldap.last.attr.memberOf]"
    if { $aux contains "TEST" } {
        $aux = 1
    } else {
        $aux = 0
    }

    switch -glob [HTTP::uri] {
            "/URI_A/*" {
                           pool /Common/P-URI_A
                       }
            "/URI_B/*" {
                           pool /Common/P-URI_B
                       }
            "/URI_C/*" {
                           pool /Common/P-URI_C
                       }
            "/URI_D/*" {
                           pool /Common/P-URI_D
                       }
            "/URI_E/*" {
                           if {($aux == 0)}{
                               discard
                           }
                       }
            default {
                       pool /Common/P-URI_DEFAULT
            }
     }
}
