In response to your question about increasing the size
of a user porfile beyond 10 characters. The answer is
NO …. this is a permanent restraint IBM has put on the security process of the iSeries.
Nor should you want to change the length. Ten characters is enough to identify trillions of users. You can’t have that many users on the system, so there is no reason to need longer values.
Note that <b>proper</b> profile names <i>should not</i> convey identifying information. You shouldn’t have a user profile for me, for example, that would be named “TOML”. Somebody scanning user profile names shouldn’t be able to connect the profile to an individual just by looking at the profile name. If an individual is to be identified, it should at least require enough authority to issue DSPUSRPRF.
It shouldn’t be enough simply to catch a glimpse of a qualified job name and link it to a particular employee. That’s how things like ‘social engineering’ manage to collect enough bits of info to cause eventual damage.
A desire to increase the length is going in a wrong direction.
