The Sourcing of Startup Files for the Profile Shell User

The algorithm for reading .dtprofile files when an account has a profile shell as its login shell prevents an account from executing commands that are not permitted to the account.

When a user's login shell is specified as the pfsh, pfcsh, or pfksh, the window system does not consult an account's home directory. The window system uses either the default /usr/dt/config/sys.dtprofile or a version modified by the Security Administrator role in /etc/dt/config/sys.dtprofile.
