Hi,

Yet another opportunity to demonstrate my ignorance has arisen.

I have attempted to introduce SUPERUSER granularity by exploiting UNIXPRIV 
within RACF. I have defined a number of resources including 
SUPERUSER.FILESYS.MOUNT and given UNIXGRP (my chosen name) update access which 
according to the z/OS 1.6 UNIX System Services Planning manual should give the 
users in the group the ability to issue MOUNT commands either via TSO or the 
shell.

What actually occurs is a security violation on class FSOBJ.

ICH408I USER(UNXSTU1 ) GROUP(UNIXGRP ) NAME(UNXSTU1 ID          ) 978 
  CL(FSOBJ   )                                                        
  INSUFFICIENT AUTHORITY TO MOUNTSETUID                               
  EFFECTIVE UID(0000000011)  EFFECTIVE GID(0000000100)                

There seems to be a dearth of information on FSOBJ but the implication is that 
FSOBJ is only used for Audit purposes and that resources cannot be defined 
under it.

Obviously if a user is given SUPERUSER capability then the above message does 
not arise, but granting SUPERUSER to all and sundry is not an optimum route.

Any assistance or advice would be appreciated.

Kind regards - Terry
