WORKERS AHEAD!

You are viewing the development documentation for the Apereo CAS server. The functionality presented here is not officially released yet. This is a work in progress and will be continually updated as development moves forward. You are most encouraged to test the changes presented.

MongoDb Authentication

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

<dependency>
    <groupId>org.apereo.cas</groupId>
    <artifactId>cas-server-support-mongo</artifactId>
    <version>${cas.version}</version>
</dependency>

implementation "org.apereo.cas:cas-server-support-mongo:${project.'cas.version'}"

dependencyManagement {
    imports {
        mavenBom "org.apereo.cas:cas-server-support-bom:${project.'cas.version'}"
    }
}

dependencies {
    implementation "org.apereo.cas:cas-server-support-mongo"
}

dependencies {
    implementation enforcedPlatform("org.apereo.cas:cas-server-support-bom:${project.'cas.version'}")
    implementation platform(org.springframework.boot.gradle.plugin.SpringBootPlugin.BOM_COORDINATES)

    implementation "org.apereo.cas:cas-server-support-mongo"
}

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`. When used with `PasswordEncoderTypes#PBKDF2`, it should be one of `PBKDF2WithHmacSHA1`, `PBKDF2WithHmacSHA256` or `PBKDF2WithHmacSHA512`. `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. In the event the configured resource is a Groovy script, specially if the script set to reload on changes, you may need to adjust the total number of `inotify` instances. On Linux, you may need to add the following line to `/etc/sysctl.conf`: `fs.inotify.max_user_instances = 256`. You can check the current value via `cat /proc/sys/fs/inotify/max_user_instances`. `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. In other words, you should only include this field in your
configuration if you need to modify the default value or if you need to turn on the feature controlled by the setting.}
