Attempt at fixing bug #283. There however is no solution.

There is a workaround documented in the bug report.

This patch does:

  * add server support for the LSA_DS UUID on the lsarpc pipe
  * store a list of context_ids/api_structs in the pipe_struct
    so that we don't have to lookup the function table for a pipe.
    We just match the context_id.  Note that a dce/rpc alter_context
    does not destroy the previous context so it is possible to
    have multiple bindings active on the same pipe. Observed from
    standalone win2k sp4 client.
  * added server code for DsROleGetPrimaryDOmainInfo() but disabled it
    since it causes problems enumerating users and groups from a 2ksp4
    domain member in a Samba domain.
