unable to save all settings. 1 settings saved

I'm trying to configure N95 SIP and network access by sending provisioning SMS.
Below you will find the original SMS content and binary SMSs including UDH and WSP headers and wbxml content.

The problem: When the user saves the SMS an error message: "unable to save all settings. 1 settings saved" appears and most of the configuration information is not stored.
However, when I remove the <characteristic type="APPAUTH"> section (including its </characteristic>) The SMS is accepted and saved well.

Could you let me know what am I doing wrong ?

Thanks,
Nbdr
