This functionality already exists within the API. It is not well documented - but in essence for many entity-types you can pass arbitrary attribute/value pairs in the update/create process and store them within the entity.
Largely this has been discussed as something we would like to *stop* supporting because it makes for clearly validating the inputs to the API very difficult (and allows for an unbounded dataset to be added anywhere these entities accept it). You can see in the dictbase (the link you provided shows inheritance from DictBase object: https://github.com/openstack/keystone/blob/8fb62f7b0edff8aecd12f4a3eaffe742b29a40db/keystone/common/sql/core.py#L121-L153 ) In short, yes you can do this, however not all backends supported by Keystone support this well (nor uniformly). - Marking as invalid as this functionality largely already exists (we lack good "statuses" for cases like this in LaunchPad and don't have an "already exists" status to use) ** Changed in: keystone Status: New => Invalid -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to Keystone. https://bugs.launchpad.net/bugs/1390922 Title: storing extra attributes of user in keystone Status in OpenStack Identity (Keystone): Invalid Bug description: Hi there, I am working on a rails app which provides some functionality on top of OpenStack and I want to use keystone for authentication as I don't like to have user information in multiple places. Now, the problem is that I can not store more information about user other than id, name, domain_id, password, enabled, and default_project_id*. I was wondering if you be interested in having implamentation of a key-value pair for user to store extra information. If yes, I would like to work on it. It can be really helpful for projects like ours to avoid storing user information in multiple places. In the simplest scenario, extra information can be stored as a json (or yaml or whatever) in a text column. Or to keep it more SQL-ish, it can be implemented with entity- attribute-value pattern. *https://github.com/openstack/keystone/blob/8fb62f7b0edff8aecd12f4a3eaffe742b29a40db/keystone/identity/backends/sql.py#L32 To manage notifications about this bug go to: https://bugs.launchpad.net/keystone/+bug/1390922/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
