Problems comparing memberof variable

Hi,

We have APM provisioning and trying use a iRule to discard the conection if session.ldap.last.attr.memberOf variable contains a certain value. This is the iRule:


when ACCESS_POLICY_COMPLETED {
set aux 0
if{[ACCESS::session data get "session.ldap.last.attr.memberOf"] contains "TEST" } {
$aux = 1
}
}
when HTTP_REQUEST {
switch -glob [HTTP::uri] {
            "/URI_A/*" {
                        pool /Common/P-URI_A                                
                        }
            "/URI_B/*" {
                        pool /Common/P-URI_B
                        }
            "/URI_C/*" {
                        pool /Common/P-URI_C
                        }
            "/URI_D/*" {
                        pool /Common/P-URI_D
                        }
            "/URI_E/*" {
                        if{($aux == 0)}{
                        discard
                        }
                        }
            default {
                        pool /Common/P-URI_DEFAULT
                        }
            }
}

The if{[ACCESS::session data get "session.ldap.last.attr.memberOf"] contains "TEST" } Inside to ACCESS_POLICY_COMPLETED event report this error:

Feb 15 11:37:36 slot3/DEVICENAME err tmm1[30518]: 01220001:3: TCL error: /Common/IRULE_TEST  - invalid command name "if{| CN=XXXX,OU=XXXX,OU=XXXX,OU=XXXX,OU=XXXX,DC=XXXX,DC=XXXXX,DC=XXXX | CN=XXX,OU=XXX,OU=XXX,OU=XXX,OU=XXX,DC=XXX,DC=XXX,DC=XXX |

We have several doubts:

What event is running before?(HTTP_REQUEST or ACCESS_POLICY_COMPLETED) Why does not the "if" work? by the type of variable?

Thanks!!

    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
            }
     }
}
