MongoDb Authentication

Verify and authenticate credentials against a MongoDb instance. Support is enabled by including the following dependency in the WAR overlay:

The following settings and properties are available from the CAS configuration catalog:

The configuration settings listed below are tagged as Required in the CAS configuration metadata. This flag indicates that the presence of the setting may be needed to activate or affect the behavior of the CAS feature and generally should be reviewed, possibly owned and adjusted. If the setting is assigned a default value, you do not need to strictly put the setting in your copy of the configuration, but should review it nonetheless to make sure it matches your deployment expectations.

  • cas.authn.mongo.password-encoder.encoding-algorithm=

    • The encoding algorithm to use such as MD5. Relevant when the type used is DEFAULT or GLIBC_CRYPT.

    org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.
  • cas.authn.mongo.password-encoder.type=NONE

    • Define the password encoder type to use. Type may be specified as blank or NONE to disable password encoding. It may also refer to a fully-qualified class name that implements the Spring Security's PasswordEncoder interface if you wish you define your own encoder. The following types may be used:

    • NONE: No password encoding (i.e. plain-text) takes place.
    • DEFAULT: Use the DefaultPasswordEncoder of CAS. For message-digest algorithms via character-encoding and encoding-algorithm.
    • BCRYPT: Use the BCryptPasswordEncoder based on the strength provided and an optional secret.
    • SCRYPT: Use the SCryptPasswordEncoder.
    • PBKDF2: Use the Pbkdf2PasswordEncoder based on the strength provided and an optional secret.
    • STANDARD: Use the StandardPasswordEncoder based on the secret provided.
    • SSHA: Use the LdapShaPasswordEncoder supports Ldap SHA and SSHA (salted-SHA). The values are base-64 encoded and have the label {SHA</code> or {SSHA</code> prepended to the encoded hash.
    • GLIBC_CRYPT: Use the GlibcCryptPasswordEncoder based on the encoding-algorithm, strength provided and an optional secret.
    • org.example.MyEncoder: An implementation of PasswordEncoder of your own choosing.
    • file:///path/to/script.groovy: Path to a Groovy script charged with handling password encoding operations.

    org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.
  • cas.authn.mongo.principal-transformation.groovy.location=

    • The location of the resource. Resources can be URLS, or files found either on the classpath or outside somewhere in the file system.

    org.apereo.cas.configuration.model.core.authentication.GroovyPrincipalTransformationProperties.
  • cas.authn.mongo.client-uri=

    • The connection uri to the mongodb instance. This typically takes on the form of mongodb://user:psw@ds135522.somewhere.com:35522/db. If not specified, will fallback onto other individual settings. If specified, takes over all other settings where applicable.

    org.apereo.cas.configuration.model.support.mongo.MongoDbAuthenticationProperties.
  • cas.authn.mongo.collection=

    • MongoDb database collection name to fetch and/or create.

    org.apereo.cas.configuration.model.support.mongo.MongoDbAuthenticationProperties.
  • cas.authn.mongo.database-name=

    • MongoDb database instance name.

    org.apereo.cas.configuration.model.support.mongo.MongoDbAuthenticationProperties.
  • cas.authn.mongo.host=localhost

    • MongoDb database host for authentication. Multiple host addresses may be defined, separated by comma. If more than one host is defined, it is assumed that each host contains the port as well, if any. Otherwise the configuration may fallback onto the port defined.

    org.apereo.cas.configuration.model.support.mongo.MongoDbAuthenticationProperties.
  • cas.authn.mongo.password=

    • MongoDb database password for authentication.

    org.apereo.cas.configuration.model.support.mongo.MongoDbAuthenticationProperties.
  • cas.authn.mongo.port=27017

    • MongoDb database port.

    org.apereo.cas.configuration.model.support.mongo.MongoDbAuthenticationProperties.
  • cas.authn.mongo.user-id=

    • MongoDb database user for authentication.

    org.apereo.cas.configuration.model.support.mongo.MongoDbAuthenticationProperties.
    The configuration settings listed below are tagged as Optional in the CAS configuration metadata. This flag indicates that the presence of the setting is not immediately necessary in the end-user CAS configuration, because a default value is assigned or the activation of the feature is not conditionally controlled by the setting value.

  • cas.authn.mongo.pool.idle-time=PT30S

    • The maximum idle time of a pooled connection. A zero value indicates no limit to the idle time. A pooled connection that has exceeded its idle time will be closed and replaced when necessary by a new connection.

    This settings supports the java.time.Duration syntax [?].

    org.apereo.cas.configuration.model.support.mongo.MongoDbConnectionPoolProperties.
  • cas.authn.mongo.pool.life-time=PT60S

    • The maximum time a pooled connection can live for. A zero value indicates no limit to the life time. A pooled connection that has exceeded its life time will be closed and replaced when necessary by a new connection.

    This settings supports the java.time.Duration syntax [?].

    org.apereo.cas.configuration.model.support.mongo.MongoDbConnectionPoolProperties.
  • cas.authn.mongo.pool.max-size=10

    • Maximum number of connections to keep around.

  • cas.authn.mongo.password-encoder.secret=

    • Secret to use with STANDARD, PBKDF2, BCRYPT, GLIBC_CRYPT password encoders. Secret usually is an optional setting.

    org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.
  • cas.authn.mongo.password-encoder.strength=16

    • Strength or number of iterations to use for password hashing. Usually relevant when dealing with PBKDF2 or BCRYPT encoders. Used by GLIBC_CRYPT encoders as well.

  • cas.authn.mongo.principal-transformation.blocking-pattern=
