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.

Surrogate Authentication

Surrogate authentication (impersonation), sometimes known as sudo for the web, is the ability to authenticate on behalf of another user.

The two actors in this case are:

The primary admin user whose credentials are verified upon authentication.
The surrogate user, selected by the admin, to which CAS will switch after credential verification and is one that is linked to the single sign-on session.

Example use cases for impersonation include:

Logging into an application on behalf of a user to execute and make changes.
Troubleshoot a bothersome authentication experience with an application on behalf of another user.

Surrogate authentication is enabled by including the following dependencies in the WAR overlay:

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

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

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

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

dependencies {
    /*
    The following platform references should be included automatically and are listed here for reference only.
            
    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-surrogate-webflow"
}

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.}

_{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.}

cas.authn.surrogate.separator=+

The separator character used to distinguish between the surrogate account and the admin account.

org.apereo.cas.configuration.model.support.surrogate.SurrogateAuthenticationProperties.

_{How can I configure this property?}

Configuration properties can be included and activated using the following strategies.

Note

When possible, properties should be stored in lower-case kebab format, such as cas.property-name=value. The only possible exception to this rule is when naming actuator endpoints; The name of the actuator endpoints (i.e. ssoSessions) MUST remain in camelCase mode.

CAS properties can be specified using the Java configuration property syntax in any and all .properties files:

cas.authn.surrogate.separator=+

This is the most common form of property configuration that is recognized by CAS, regardless of the actual property source, which might in fact be managed separately outside the CAS environment, by another system or cloud framework.

CAS properties can be specified using the YAML syntax:

cas: 
  authn: 
    surrogate: 
      separator: 

Note that YAML is very specific about structure and indentation. Be sure to verify the correctness of the final result with your YAML validator of choice.

CAS properties can be passed to the CAS web application as system properties, when the application is launched:

java -Dcas.authn.surrogate.separator="+" -jar build/libs/cas.war

The above example assumes that the CAS web application is packaged as cas.war and can be found in the build/libs directory. Note the placement of the system property which must be specified before the CAS web application is launched.

CAS properties can specified as system environment variables before the CAS web application is launched:

export CAS_AUTHN_SURROGATE_SEPARATOR="+"

java -jar build/libs/cas.war

The above example assumes that the CAS web application is packaged as cas.war and can be found in the build/libs directory.

CAS properties can be passed to the CAS web application as command-line arguments, when the application is launched:

java -jar build/libs/cas.war --cas.authn.surrogate.separator="+"

The above example assumes that the CAS web application is packaged as cas.war and can be found in the build/libs directory.

cas.authn.surrogate.tgt.time-to-kill-in-seconds=1800

Timeout in seconds to kill the surrogate session and consider tickets expired.

Configuration Metadata

The collection of configuration properties listed in this section are automatically generated from the CAS source and components that contain the actual field definitions, types, descriptions, modules, etc. This metadata may not always be 100% accurate, or could be lacking details and sufficient explanations.

Be Selective

This section is meant as a guide only. Do NOT copy/paste the entire collection of settings into your CAS configuration; rather pick only the properties that you need. Do NOT enable settings unless you are certain of their purpose and do NOT copy settings into your configuration only to keep them as reference. All these ideas lead to upgrade headaches, maintenance nightmares and premature aging.

YAGNI

Note that for nearly ALL use cases, declaring and configuring properties listed here is sufficient. You should NOT have to explicitly massage a CAS XML/Java/etc configuration file to design an authentication handler, create attribute release policies, etc. CAS at runtime will auto-configure all required changes for you. If you are unsure about the meaning of a given CAS setting, do NOT turn it on without hesitation. Review the codebase or better yet, ask questions to clarify the intended behavior.

Naming Convention

Property names can be specified in very relaxed terms. For instance cas.someProperty, cas.some-property, cas.some_property are all valid names. While all forms are accepted by CAS, there are certain components (in CAS and other frameworks used) whose activation at runtime is conditional on a property value, where this property is required to have been specified in CAS configuration using kebab case. This is both true for properties that are owned by CAS as well as those that might be presented to the system via an external library or framework such as Spring Boot, etc.

Note

Settings and properties that are controlled by the CAS platform directly always begin with the prefix cas. All other settings are controlled and provided to CAS via other underlying frameworks and may have their own schemas and syntax. BE CAREFUL with the distinction. Unrecognized properties are rejected by CAS and/or frameworks upon which CAS depends. This means if you somehow misspell a property definition or fail to adhere to the dot-notation syntax and such, your setting is entirely refused by CAS and likely the feature it controls will never be activated in the way you intend.

Validation

Configuration properties are automatically validated on CAS startup to report issues with configuration binding, specially if defined CAS settings cannot be recognized or validated by the configuration schema. The validation process is on by default and can be skipped on startup using a special system property SKIP_CONFIG_VALIDATION that should be set to true. Additional validation processes are also handled via Configuration Metadata and property migrations applied automatically on startup by Spring Boot and family.

Indexed Settings

CAS settings able to accept multiple values are typically documented with an index, such as cas.some.setting[0]=value. The index [0] is meant to be incremented by the adopter to allow for distinct multiple configuration blocks.

Account Storage

The following account stores may be configured and used to locate surrogates authorized for a particular user.

Static

Surrogate accounts may be defined statically in the CAS configuration.

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

cas.authn.surrogate.simple.surrogates=

Define the list of accounts that are allowed to impersonate. This is done in a key-value structure where the key is the admin user and the value is a comma-separated list of identifiers that can be impersonated by the admin-user.

Session Expiration

An impersonation session can be assigned a specific expiration policy that would control how long a surrogate session may last. This means that the SSO session established as part of impersonation will rightly vanish, once the expiration policy dictates as such. It is recommended that you keep the expiration length short (i.e. 30 minutes) to avoid possible security issues.

Remember

The expiration policy assigned to impersonation sessions is expected to be shorter than the normal expiration policy assigned to non-surrogate sessions. In other words, if the usual expiration policy that controls the single sign-on session is set to last 2 hours, the surrogate session expiration is expected to be a time period less than or equal to 2 hours.

Surrogate Attributes

Upon a successful surrogate authentication event, the following attributes are communicated back to the application in order to detect an impersonation session:

Attribute	Instructions
`surrogateEnabled`	Boolean to indicate whether session is impersonated.
`surrogatePrincipal`	The admin user whose credentials are validated and acts as the impersonator.
`surrogateUser`	The surrogate user that is impersonated.

Surrogate Access Strategy

Please see this guide.

Surrogate Audits

Surrogate authentication events are by default tracked in the audit logs:

=============================================================
WHO: (Primary User: [casuser], Surrogate User: [testuser])
WHAT: ST-1-u_R_SyXJJlENS0fBLwpecNE for https://example.app.edu
ACTION: SERVICE_TICKET_CREATED
APPLICATION: CAS
WHEN: Mon Sep 11 12:55:07 MST 2017
CLIENT IP ADDRESS: 127.0.0.1
SERVER IP ADDRESS: 127.0.0.1
=============================================================

Additionally, failure and success events may also communicated via SMS and/or email messages to relevant parties.

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

cas.authn.surrogate.mail.attribute-name=

Principal attribute names that indicates the destination email address for this message. The attributes must already be resolved and available to the CAS principal. When multiple attributes are specified, each attribute is then examined against the available CAS principal to locate the email address value, which may result in multiple emails being sent.

This setting supports the Spring Expression Language.

cas.authn.surrogate.mail.text=

Email message body. Could be plain text or a reference to an external file that would serve as a template.

If specified as a path to an external file with an extension .gtemplate, then the email message body would be processed using the Groovy template engine. The template engine uses JSP style <% %> script and <%= %> expression syntax or GString style expressions. The variable out is bound to the writer that the template is being written to.
