VPE logon page : how to set correctly USERNAME and DOMAIN prior to call the AD ...

Salut Stanislas, OK I finally found MY problem ... It was a bit stupid : to get a value Inside the uri I had changed the uri itself ! So and then when it goes to the adfs server, request has failed.

I corrected my error, remains me to be sure I'm using the correct variables : I'm using GLOBAL one,

When HTTP_REQUEST {
  set namevals [split [HTTP::query] "&"]
  for {set i 0} {$i < [llength $namevals]} {incr i} {
    set params [split [lindex $namevals $i] "="]
    set pnum [expr $i+1]
    if { [lindex $params 0] contains "username" } 
       { set static::tmp_username [string map -nocase {"%40domaine-test.com" ""} [URI::query [HTTP::uri] [lindex $params 0]]]
    }
  }
}

when ACCESS_POLICY_AGENT_EVENT {
  switch [ACCESS::policy agent_id] {
    "O365_USERNAME" {
      ACCESS::session data set session.custom.username $static::tmp_username
    }
  }
