[SR-Users] Authenticated ACK: $au not set?

Hi Gang

I have this code snipplet:

if (has_credentials("$fd")) { xlog("L_INFO", "$cfg(route): got $rm with credentials. Validate them!\n"); if ($aU == $null) { xlog("L_INFO", "$cfg(route): no auth user, send challenge\n"); } auth_challenge("$fd", "0"); exit; } }

Please don't ask if this makes sense, it's a constructed snipplet to show the situation.

If $rm is INVITE, this works fine, no challenge is being sent, $au is populated. If $rm is ACK (some CPE seem to send the Credentials with each message) then $au is $null, auth_challenge is called and fails.

Mit freundlichen Grüssen
