Hi, everyone, In the last two weeks, I have finished the generation capability of the authorization daemon, it mainly includes generating and parse XACML request and response, generating signature using SHA-256. Also I have finished coding the connection part using Mercury, but it still need tests for the MPI mode. In the next weeks, we will try to figure out remaining communication problems using Mercury between Authorization daemon and client, fileserver daemon.
