The Single_Host_Data structure allows a client to send machine-specific information within an authentication exchange to services on the same machine. The client can produce additional information to be processed in an implementation-specific way when the client and server are on the same host. If the server and client platforms are different or if they are on different hosts, then the information MUST be ignored. Any fields after the MachineID field MUST be ignored on receipt.

From http://www.ietf.org/proceedings/72/slides/sasl-2.pdf:

tls-server-end-point:

The hash of the TLS server's end entity certificate as it appears, octet for octet, in the server's Certificate message (note that the Certificate message contains a certificate_list, the first element of which is the server's end entity certificate.) The hash function to be selected is as follows: if the certificate's signature hash algorithm is either MD5 or SHA-1, then use SHA-256, otherwise use the certificate's signature hash algorithm.
