Georgy, For Solum, let's refrain from storing any secrets, whether they be passwords or trusts, or tokens. I definitely don't want to be in the business of managing how to secure them in an SQL database. I don't even want "admin password" values to appear in the configuration files. I'd prefer to take a hard dependency on barbican[1], and store them in there, where they can be centrally fortified with encryption and access controls, accesses can be logged, they can be revoked, and we have a real auditing story for enterprises who have strict security requirements.

It really solves the problem with trust expiration. I really like an idea to restrict trust to specific roles. This is great. As you mentioned, you use sql to store trusts information. Do you use any encryption for that? I am thinking from security perspective, if you have trust information in DB it might be not safe as this trust is a long term authentication.

Trusts can be given an expiration but if an expiration is not given the trust is valid until it is explicitly revoked (taken from the link above): Optionally, the trust may only be valid for a specified time period, as defined by expires_at. If noexpires_at is specified, then the trust is valid until it is explicitly revoked. Trusts can also be given 'uses' so that you can set a limit to how many times a trust will issue a token to the trustee. That functionality hasn't landed yet but it is up for review: https://review.openstack.org/#/c/56243/ Hope this helps!

Trusts are long term entities and a service should keep them for a long time. I want to understand what are best practices for working with trusts and storing them in a service? What are the options to keep trust? I see obvious approaches like keep them in a service DB or keep them in memory. Are there any other approaches? Is there a proper way to renew trust? For example if I have a long term task which is waiting for external event, how to keep trust fresh for a long and unpredicted period?
