3.1.5.1.2 Receiving a wsignin1.0 Request That Specifies a ttpindex of 0

When the IP/STS receives a wsignin1.0 request that specifies a ttpindex parameter value of 0, the IP/STS MUST process the wsignin1.0 request (as specified in [MS-MWBF] section 3.1.5.4) up to the point where the IP/STS has constructed the RSTR element (as specified in [MS-MWBF] section 3.1.5.4.6). The IP/STS MUST apply the following transforms to the RSTR element to produce the pending result:

  1. Convert the XML string to binary data by applying UTF-8 encoding, as specified in [RFC2279].

  2. Compress the result from step 1 to the zlib format (as specified in [RFC1950]) by using the deflate algorithm (as specified in [RFC1951]).

  3. Base64-encode the result from step 2, as specified in [RFC2045] section 6.8.

The IP/STS MUST respond as specified in section 3.1.5.1.4, by using the result from step 3 as the pending result.
