May I ask if we have similar feature of auto provisioning of subscribers who are trying to camp to the network similar to auth-policy accept-all in osmo-nitb? Is the new version supports also the auto provisioning of subscribers?

Hi Justin, Yes. There is something similar.

In osmo-hlr you need:

hlr
 subscriber-create-on-demand 5 none

or similar.

Check inline help for what "5" and "none" mean. These are options.
