Authorisation store configuration
Authorisation codes, until they get exchanged for a token, or expire.
Identifier-based access tokens, until they expire or get revoked. Self - contained (JWT-encoded) are not saved on the server.
Refresh tokens, until they get revoked or expire (unless the refresh token is permanent).
Long-lived (persisted) OAuth 2.0 authorisations, to remember previously given consent by end-users to clients, until the authorisation gets revoked.
Revocation journal entries.
The authorisation store configuration is located in the following file:
The configuration properties are grouped into sections:
- Web API settings
- Authorisation code settings
- Access token settings
- Refresh token settings
- Miscellaneous options
Any property in the configuration file can be overridden with a Java system property, e.g. by setting the optional -D argument at JVM startup:
The external configuration guide has tips for setting system properties from environment variables, local files and other locations.
1. Web API
The access token for the authorisation store web API, represented by its SHA-256 hash (in hexadecimal format). The hashed storage is intended to prevent accidental leakage of the token through configuration files, logs, etc. The token is of type Bearer, non-expiring and must contain at least 32 random alphanumeric characters to make brute force guessing impractical. If not specified the web API will be disabled.
Additional access tokens, to facilitate token roll-over or for other needs,
can be configured by appending a dot (.) with a unique label to the property
name, e.g. as
authzStore.apiAccessTokenSHA256.1=abc.... Since v10.0.
The hash for a token with value
Optional secondary access token for the authorisation session store web API. Has the same format as sessionStore.apiAccessTokenSHA256. Must not be set if not needed.
authzStore.apiAccessTokenSHA256.* from v10.0 on.
2. Authorisation code
authzStore.code.* group contains a single property which sets the
lifetime of issued authorisation codes.
The authorisation code lifetime in seconds. Should be long enough to permit a client to make a token request to exchange the code for an ID / access token. Must not be shorter than 0 seconds (1 minute) or longer than 600 seconds (10 minutes).
3. Access token
authzStore.accessToken.* properties set the default preferences of issued
OAuth 2.0 access tokens such
as lifetime and encoding.
The default access token lifetime in seconds. Can be overridden by individual authorisations. Must be a positive integer.
Supported JWS algorithms:
- RS256 (recommended)
- EdDSA (with Ed25519 key, recommended for high-performance and compact signatures)
Supported JWE algorithms:
Supported JWE methods:
- A128GCM (recommended)
The size in bytes of the generated (using a secure function) identifiers (see jti claim) in self-contained (JWT-encoded) access tokens. Must be at least 8 bytes long to minimise the likelihood of identifier collision.
Discontinued in v7.9, JTI length is always 8 bytes.
true an access token can be inspected without presenting the master
Bearer access token to the authorisation store web
- c2id-1.1 -- Connect2id server specific profile, available since v7.17, with the JWT "typ" (type) header set to "at+jwt". This is the default profile if not specified.
- c2id-1.0 -- Connect2id server specific profile, available since v1.0, outputs identical JWT claims as c2id-1.1 but doesn't set the JWT "typ" (type) header.
- oauth-1.0 -- Standard profile in development at the OAuth working group.
4. Refresh token
authzStore.refreshToken.* properties set the default preferences of
issued OAuth 2.0 refresh tokens.
The default refresh token lifetime in seconds. Can be overridden by individual authorisations. If zero or omitted defaults to permanent (no expiration). Must be zero or a positive integer. The default value is zero (no expiration).
To set the default refresh token lifetime to one week:
true causes the refresh token to be updated (rotated) on each
authorisation update and on each refresh token use. Applies to long-lived
authorisations only, the refresh tokens for short-lived (transient)
authorisations are not affected. The default value is
false (no update).
5. Authorisation store options
authzStore.options.* properties contains two settings.
With an enabled highly-available mode the authorisation store will continue providing basic service even if the backend database is down or disconnected. The required data will be served from the caches if possible and database connection exceptions will not cause requests to fail (they will be logged at ERROR level however).
List of the optional authorisation attributes that are to be automatically discarded from new authorisation objects, in order to conserve cache memory and back-end storage.
true the Connect2id server will support retrieval of legacy plain keys for
identifier-based access tokens from storage after upgrading to Connect2id
false to ignore such keys which will
cause the introspection of
the linked access tokens to flag them as invalid. Note that enabling this
configuration imposes imposes additional database reads and a performance
penalty during introspection. The default value is
false (no support for
legacy plain access token keys).
true the Connect2id server will issue refresh tokens in the legacy format
supported up to v7.x. Intended to facilitate seamless rolling upgrades to v8.x
and later. The default value is
false (no issue of legacy refresh tokens).
