Hi,

you should get the body of the header, remove the header, do a subst (to change the username) and insert the hdr back:

$var(body) = $hdr(Authorization);
$var(new_body) = $(var(body){re.subst,reg_exp}) ; // see http://www.opensips.org/Documentation/Script-Tran-2-1#toc75
remove_hf("Authorization");
append_hf("Authorization: $var(new_body)\r\n");

    Hi Nirali,

    You could try to do it with some regexp and transformations, but
    your authentication will fail as the "response" will not match the
    username - the response is computed based in username, password, etc.
