To check a user's authority to create a new file or open an existing
file, the SFS server calls the SFS object authorization checking CSL
routine. A new file is indicated by FN in the object description in
the object list on the authorization call. The IBM-supplied DMSUAUTH
routine calls a series of RACROUTE calls to the ESM.
