Very Computer

 However, when I tried to login as "root.admin", and then subsequently
re-login as operator's Kerberos id, only then  the above command (sysctl
Efence 33) works without any errors.

 Do anyone know why is this so?

 For information, the ssp versions are listed as follow:

   ssp.authent                2.2.0.2    A    SP Authentication Server
   ssp.basic                  2.2.0.9    A    SP System Support Package
   ssp.clients                2.2.0.8    A    SP Authenticated Client
Commands
   ssp.css                    2.2.0.9    A    SP Communication Subsystem

   ssp.sysctl                 2.2.0.1    A    SP Sysctl Package

 Thanks in advance.

There's a perl script referenced in the ACL file that acts as
a wrapper for sysctl - just for the purpose you suggest.

As for the Kerberos problem you mention, sound like you need to
make sure you're logged on as a (any) non-root user, then run
kinit for the non-root principal (not root.admin).  Make sure
your PATH statement has the needed commands.

I've used sysctl in scripts for operator reboots, etc., very handy item.

Note:
(by the look of your PSSP code, you need PTF's and make sure to
commit the ones you have in applies state first.)
