CAS Properties

Various properties can be specified in CAS either inside configuration files or as command line switches. This section provides a list common CAS properties and references to the underlying modules that consume them.

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.

Note that property names can be specified in very relaxed terms. For instance cas.someProperty, cas.some-property, cas.some_property and CAS_SOME_PROPERTY are all valid names.

The following list of properties are controlled by and provided to CAS. Each block, for most use cases, corresponds to a specific CAS module that is expected to be included in the final CAS distribution prepared during the build and deployment process.

YAGNI

Note that for nearly ALL use cases, simply declaring and configuring properties listed below is sufficient. You should NOT have to explicitly massage a CAS XML configuration file to design an authentication handler, create attribute release policies, etc. CAS at runtime will auto-configure all required changes for you.

General

A number of CAS configuration options equally apply to a number of modules and features. To understand and take note of those options, please review this guide.

Configuration Storage

Standalone

CAS by default will attempt to locate settings and properties inside a given directory indicated under the setting name cas.standalone.config and otherwise falls back to using /etc/cas/config.

There also exists a cas.standalone.config.file which can be used to directly feed a collection of properties to CAS in form of a file or classpath resource. This is specially useful in cases where a bare CAS server is deployed in the cloud without the extra ceremony of a configuration server or an external directory for that matter and the deployer wishes to avoid overriding embedded configuration files.

Spring Cloud

The following settings are to be loaded by the CAS configuration runtime, which bootstraps the entire CAS running context. They are to be put inside the src/main/resources/bootstrap.properties of the configuration server itself. See this guide for more info.

The configuration server backed by Spring Cloud supports the following profiles.

Native

Load settings from external properties/yaml configuration files.

1

# spring.profiles.active=native

# The configuration directory where CAS should monitor to locate settings.
# spring.cloud.config.server.native.searchLocations=file:///etc/cas/config

Git Repository

# The location can point to an HTTP/SSH/directory.
# spring.cloud.config.server.git.uri=https://github.com/repoName/config
# spring.cloud.config.server.git.uri=file://${user.home}/config

# The credentials used to authenticate git requests, specially
# when using HTTPS. If connecting to the repository via SSH, remember
# to register your public keys with an SSH agent just as your normal would have
# with any other public repository.
# spring.cloud.config.server.git.username=
# spring.cloud.config.server.git.password=

The above configuration also applies to online git-based repositories such as Github, BitBucket, etc.

Vault

4
# cas.standalone.config.security.alg=PBEWithMD5AndTripleDES
# cas.standalone.config.security.provider=BC
# cas.standalone.config.security.iterations=
# cas.standalone.config.security.psw=

The above settings may be passed to CAS using any of the strategies outline here, though it might be more secure to pass them to CAS as either command-line or system properties.

Spring Cloud

Encrypt and decrypt configuration via Spring Cloud, if the Spring Cloud configuration server is used.

SSL Valve

The Tomcat SSLValve is a way to get a client certificate from an SSL proxy (e.g. HAProxy or BigIP F5) running in front of Tomcat via an HTTP header. If you enable this, make sure your proxy is ensuring that this header doesn’t originate with the client (e.g. the browser).

# cas.server.name=https://cas.example.org:8443
# cas.server.prefix=https://cas.example.org:8443/cas
# cas.host.name=

CAS Banner

On startup, CAS will display a banner along with some diagnostics info. In order to skip this step and summarize, set the system property -DCAS_BANNER_SKIP=true.

Spring Boot Endpoints

The following properties describe access controls and settings for the /status endpoint of CAS which provides administrative functionality and oversight into the CAS software. These endpoints are specific to Spring Boot.

# cas.adminPagesSecurity.users=file:/etc/cas/config/adminusers.properties
# cas.adminPagesSecurity.adminRoles[0]=ROLE_ADMIN

# cas.adminPagesSecurity.actuatorEndpointsEnabled=true

The format of the adminusers.properties file which houses a list of authorized users to access the admin pages via CAS is:

1
# casuser=notused,ROLE_ADMIN

The format of the file is as such:

  • casuser: This is the authenticated user id received from CAS
  • notused: This is the password field that isn’t used by CAS. You could literally put any value you want in its place.
  • ROLE_ADMIN: Role assigned to the authorized user as an attribute, which is then cross checked against CAS configuration.

Note that in certain cases, CAS authentication is able to retrieve and resolve attributes from the authentication source in the same authentication request, which would eliminate the need for configuring a separate attribute repository specially if both the authentication and the attribute source are the same. Using separate repositories should be required when sources are different, or when there is a need to tackle more advanced attribute resolution use cases such as cascading, merging, etc. See this guide for more info.

Attributes for all sources are defined in their own individual block. CAS does not care about the source owner of attributes. It finds them where they can be found and otherwise, it moves on. This means that certain number of attributes can be resolved via one source and the remaining attributes may be resolved via another. If there are commonalities across sources, the merger shall decide the final result and behavior.

The story in plain english is:

  • I have a bunch of attributes that I wish to resolve for the authenticated principal.
  • I have a bunch of sources from which said attributes are retrieved.
  • Figure it out.

Note that attribute repository sources, if/when defined, execute in a specific order. This is important to take into account when attribute merging may take place. By default, the execution order is the following but can be adjusted per source:

  1. LDAP
  2. JDBC
  3. JSON
  4. Groovy
  5. Internet2 Grouper
  6. Shibboleth
  7. Stub

Note that if no explicit attribute mappings are defined, all permitted attributes on the record may be retrieved by CAS from the attribute repository source and made available to the principal. On the other hand, if explicit attribute mappings are defined, then only mapped attributes are retrieved.

Merging Strategies

The following mergeing strategies can be used to resolve conflicts when the same attribute are found from multiple sources:

Type Description
REPLACE Overwrites existing attribute values, if any.
ADD Retains existing attribute values if any, and ignores values from subsequent sources in the resolution chain.
MERGE Combines all values into a single attribute, essentially creating a multi-valued attribute.

Stub

Static attributes that need to be mapped to a hardcoded value belong here.

Encode Database Authentication

A JDBC querying handler that will pull back the password and the private salt value for a user and validate the encoded password using the public salt value. Assumes everything is inside the same database table. Supports settings for number of iterations as well as private salt.

This password encoding method combines the private Salt and the public salt which it prepends to the password before hashing. If multiple iterations are used, the bytecode hash of the first iteration is rehashed without the salt values. The final hash is converted to hex before comparing it to the database value.

LDAP Authentication

CAS authenticates a username/password against an LDAP directory such as Active Directory or OpenLDAP. There are numerous directory architectures and we provide configuration for four common cases.

Note that CAS will automatically create the appropriate components internally based on the settings specified below. If you wish to authenticate against more than one LDAP server, simply increment the index and specify the settings for the next LDAP server.

Note: Failure to specify adequate properties such as type, ldapUrl, etc will simply deactivate LDAP authentication altogether silently.

Note: Attributes retrieved as part of LDAP authentication are merged with all attributes retrieved from other attribute repository sources, if any. Attributes retrieved directly as part of LDAP authentication trump all other attributes.

To learn more about this topic, please review this guide.

The following authentication types are supported:

Type Description
AD Acive Directory - Users authenticate with sAMAccountName typically using a DN format.
AUTHENTICATED Manager bind/search type of authentication. If principalAttributePassword is empty then a user simple bind is done to validate credentials. Otherwise the given attribute is compared with the given principalAttributePassword using the SHA encrypted value of it.
DIRECT Compute user DN from a format string and perform simple bind. This is relevant when no search is required to compute the DN needed for a bind operation. This option is useful when all users are under a single branch in the directory, e.g. ou=Users,dc=example,dc=org, or the username provided on the CAS login form is part of the DN, e.g. uid=%s,ou=Users,dc=exmaple,dc=org
ANONYMOUS Similar semantics as AUTHENTICATED except no bindDn and bindCredential may be specified to initialize the connection. If principalAttributePassword is empty then a user simple bind is done to validate credentials. Otherwise the given attribute is compared with the given principalAttributePassword using the SHA encrypted value of it.

Connection Strategies

If multiple URLs are provided as the ldapURL this describes how each URL will be processed.

Provider Description
DEFAULT The default JNDI provider behavior will be used.
ACTIVE_PASSIVE First LDAP will be used for every request unless it fails and then the next shall be used.
ROUND_ROBIN For each new connection the next url in the list will be used.
RANDOM For each new connection a random LDAP url will be selected.
DNS_SRV LDAP urls based on DNS SRV records of the configured/given LDAP url will be used.

Connection Initialization

LDAP connection configuration injected into the LDAP connection pool can be initialized with the following parameters:

Behavior Description
bindDn/bindCredential provided Use the provided credentials to bind when initializing connections.
bindDn/bindCredential set to * Use a fast-bind strategy to initialize the pool.
bindDn/bindCredential set to blank Skip connection initializing; perform operations anonymously.
SASL mechanism provided Use the given SASL mechanism to bind when initializing connections.

Validators

The following LDAP validators can be used to test connection health status:

Type Description
NONE No validation takes place.
SEARCH Validates a connection is healthy by performing a search operation. Validation is considered successful if the search result size is greater than zero.
COMPARE Validates a connection is healthy by performing a compare operation.

Passivators

The following options can be used to passivate bjects when they are checked back into the LDAP connection pool:

Type Description
NONE No passivation takes place.
CLOSE Passivates a connection by attempting to close it.
BIND Passivates a connection by performing a bind operation on it.

Why Passivators?

You may receive unexpected LDAP failures, when CAS is configured to authenticate using DIRECT or AUTHENTICATED types and LDAP is locked down to not allow anonymous binds/searches. Every second attempt with a given LDAP connection from the pool would fail if it was on the same connection as a failed login attempt, and the regular connection validator would similarly fail. When a connection is returned back to a pool, it still may contain the principal and credentials from the previous attempt. Before the next bind attempt using that connection, the validator tries to validate the connection again but fails because it’s no longer trying with the configured bind credentials but with whatever user DN was used in the previous step. Given the validation failure, the connection is closed and CAS would deny access by default. Passivators attempt to reconnect to LDAP with the configured bind credentials, effectively resetting the connection to what it should be after each bind request.

X509 Authentication

To learn more about this topic, please review this guide.

Principal Resolution

X.509 principal resolution can act on the following principal types:

Type Description
SERIAL_NO Resolve the principal by the serial number with a configurable radix, ranging from 2 to 36. If radix is 16, then the serial number could be filled with leading zeros to even the number of digits.
SERIAL_NO_DN Resolve the principal by serial number and issuer dn.
SUBJECT Resolve the principal by extracting one or more attribute values from the certificate subject DN and combining them with intervening delimiters.
SUBJECT_ALT_NAME Resolve the principal by the subject alternative name extension.
SUBJECT_DN The default type; Resolve the principal by the certificate’s subject dn.

CRL Fetching / Revocation

CAS provides a flexible policy engine for certificate revocation checking. This facility arose due to lack of configurability in the revocation machinery built into the JSSE.

Available policies cover the following events:

  • CRL Expiration
  • CRL Unavailability

In either event, the following options are available:

Type Description
ALLOW Allow authentication to proceed.
DENY Deny authentication and block.
THRESHOLD Applicable to CRL expiration, throttle the request whereby expired data is permitted up to a threshold period of time but not afterward.

Revocation certificate checking can be carried out in one of the following ways:

Type Description
NONE No revocation is performed.
CRL The CRL URI(s) mentioned in the certificate cRLDistributionPoints extension field. Caches are available to prevent excessive IO against CRL endpoints; CRL data is fetched if does not exist in the cache or if it is expired.
RESOURCE A CRL hosted at a fixed location. The CRL is fetched at periodic intervals and cached.

To fetch CRLs, the following options are available:

Type Description
RESOURCE By default, all revocation checks use fixed resources to fetch the CRL resource from the specified location.
LDAP A CRL resource may be fetched from a pre-configured attribute, in the event that the CRL resource location is an LDAP URI

WS-Fed Delegated Authentication

To learn more about this topic, please review this guide.

Attribute Types

In order to construct the final authenticated principal, CAS may be configured to use the following strategies when collecting principal attributes:

Type Description
CAS Use attributes provided by the delegated WS-Fed instance.
WSFED Use attributes provided by CAS’ own attribute resolution mechanics and repository.
BOTH Combine both the above options, where CAS attribute repositories take precedence over WS-Fed.
