VCS prompts for user name and password information when non-root users run haxxx commands. Use the halogin command to save the authentication information so that you do not have to enter your credentials every time you run a VCS command. Note that you may need specific privileges to run VCS commands.
When you run the halogin command, VCS stores encrypted authentication information in the user's home directory. For clusters that run in secure mode, the command also sets up a trust relationship and retrieves a certificate from an authentication broker.
If you run the command for different hosts, VCS stores authentication information for each host. After you run the command, VCS stores the information until you end the session.
For clusters that run in secure mode, you also can generate credentials for VCS to store the information for 24 hours or for eight years and thus configure VCS to not prompt for passwords when you run VCS commands as non-root users.
Root users do not need to run halogin when running VCS commands from the local host.
