What is a user?
A user is someone whose identity information is available via SimpleID. Typically users will be able to log into other web sites or applications through an identity protocol supported by SimpleID.
Each SimpleID installation must contain at least one user. A single SimpleID installation is able to host multiple users.
What information does SimpleID store with a user?
At a minimum, the following information is stored with a user:
A user name unique to the SimpleID installation. SimpleID stores user information using the user name as the file name. As a result, a user name must be able to be used as a valid file name under your server's operating system.
While file name rules vary between operating systems, generally user names consisting of alphanumeric characters would be acceptable.
Credentials, which can be used to authenticate the user. By default, password based credentials are used, although other kinds of credentials can be supported through the use of authentication scheme modules.
For each identity protocol, some way of linking the user's identity to the SimpleID server. Normally this involves a protocol-specific identifier of some kind. For example, for OpenID, this is the identity URI.
How to create a new user
Under the default SimpleID settings, creating a new user involves the following steps.
Decide on the user name. As noted above, this must be able to be used as a valid file name.
Decide on the password. Choosing a good password is very important, as it protects your identity from unauthorised access. Wikipedia contains information on how to choose a secure password. You may wish to use the Diceware method to generate your password.
You will need to encrypt your password using PBKDF2. You can do this using the simpleid-tool.
Tell SimpleID about that identity by creating a user file. An user file (previously an identity file) is a YAML-formatted file containing information about a particular SimpleID user. They are stored in the identities directory and are named
username.user.yml, where username is the name of the SimpleID user.
An example user file is
example.user.yml.distin the identities directory. Make a copy of this file and rename it
username.user.yml, where username is the user name with which you want to log into SimpleID.
