Defining SMB administrators

The SMB Administrator must have root authority on the z/OS® system. This means a z/OS user ID with a UID=0 or superuser authority assigned through the BPX.SUPERUSER resource in the RACF® FACILITY class or the equivalent for another security-based product. This authority is required in order to issue certain commands and to define shared directories and shared printers. For additional details on assigning superuser authority, see the topic on using the BPX.SUPERUSER resource in the FACILITY class in z/OS UNIX System Services Planning.

Two types of users can start or stop the Distributed File Service server address space and the processes controlled by DFSCNTL (see Managing SMB processes):

A user with z/OS operator privileges.
A user who has update privilege to the DFSKERN.START.REQUEST profile in the RACF FACILITY class. This profile is created during the installation of DFS.

The following environment variable should be specified in the SMB Administrator’s z/OS UNIX environment (for example, in the SMB Administrator’s $HOME/.profile file).

export _EUV_AUTOLOG=NO
