Follow the procedure for non-interactive BLCLI. In other words configure BLSSO and or the older SRP method with user_info.dat. If you search through the docs you should be able to find what to do. The SRP method is scheduled for deprecation oin the future so using SSO is preferred.
Regarding additional documentation I know of no other published / public docs.
Add user to role - remeber RBAC - this little script may help you to add user "YOU" or your server "RBAC" and give you access to run the script with no username and password
Hope that helps
if test "$SERVER_NAME" = ""; then
echo "Server Name unknown. Exiting."
BLCLI_CALL="blcli -i $USERINFO_FILE"
# Locate property
echo "Adding $SERVER_NAME to $ROLE Role"
`$BLCLI_CALL RBACRole addServer $ROLE_NAME $SERVER_NAME`
It's not really a good idea to have a user w/ no password.
You will still have to authenticate, even to enter a blank password, and if you user is in multiple roles, you will still have to select a role.
