Realms Management

Authentication Delegation

Agate is able to delegate authentication to alternate identity provider systems. Note that even if the authentication happens in this third party application, the user still need to have a profile declared in Agate. The sign-up process extracts the user information, if some are available, to assist with the creation of this profile, but afterwards only the authentication service is used.

Realm Types

LDAP Realm

A realm that authenticates users by using Lightweight Directory Access Protocol to query a Directory Access Agent. This realm uses a user’s Distinguished Name (DN) template to build queries.

Active Directory Realm

A realm tailored to a Microsoft Active Directory environment. This realm queries by using a combination of a search filter and search base.

SQL Database Realm

mysql, mariadb and postgresql are supported. This realm queries the user’s password with the salt style used by the database.

Salt styles include:

  • NO_SALT: used when the password is in plain text.
  • CRYPT: uses the database’s underlying cryptographic method to decrypt the password.
  • COLUMN: the salt column must be the second column included in the query.
  • EXTERNAL: uses the specified algorithm to decrypt the password.

Open ID Connect Realm

A realm that uses the OpenID Connect (OIDC) protocol to authenticate users. OpenID Connect Flow explains the typical authentication flow when using this type of realm.

Note

For agate to authenticate for an Application, its redirect URI must be set.
