Certificate revocation list configuration settings

Use this page to specify a list of certificate revocations that check the validity of a certificate. The application server checks the certificate revocation lists (CRL) to determine the validity of the client certificate. A certificate that is found in a certificate revocation list might not be expired, but is no longer trusted by the certificate authority (CA) that issued the certificate. The CA might add the certificate to the certificate revocation list if it believes that the client authority is compromised. To view the administrative console panel for the collection certificate store on the cell level, complete the following steps:

1. Click Security > Web services.

2. Under additional properties, click Collection certificate store.

3. Click the name of a configured collection certificate store or create a new collection certificate store first.

4. Under Additional properties, click Certificate revocation lists > New to specify the path to a new list or click the name of a certificate revocation list to modify its path.

To view the administrative console panel for the collection certificate store on the server level, complete the following steps:

1. Click Servers > Application servers > server_name.

2. Under Security, click Web services: Default bindings for Web services security.

3. Under Additional properties, click Collection certificate store.

4. Click the name of a configured collection certificate store or create a new collection certificate store first.

5. Under Additional properties, click Certificate revocation lists > New to specify the path to a new list or click the name of a certificate revocation list to modify its path.

To view this administrative console page for the collection certificate store on the application level, complete the following steps:

1. Click Applications > Enterprise applications > application_name.

2. Click Manage modules > URI_name.

3. Under Web Services Security Properties, you can access collection certificate stores for the following bindings:

   • For the Request generator, click Web services: Client security bindings. Under Request generator (sender) binding, click Edit custom > Collection certificate store.

   • For the Request consumer, click Web services: Server security bindings. Under Request consumer (receiver) binding, click Edit custom > Collection certificate store.

   • For the Response generator, click Web services: Server security bindings. Under Response generator (sender) binding, click Edit custom > Collection certificate store.

   • For the Response consumer, click Web services: Client security bindings. Under Response consumer (receiver) binding, click Edit custom > Collection certificate store.

4. Click the name of a configured collection certificate store or create a new collection certificate store first.

5. Under Additional properties, click Certificate revocation lists > New to specify the path to a new list or click the name of a certificate revocation list to modify its path.

Certificate revocation list path

Specifies a fully qualified path to the location where you can find the list of certificates that are not valid.

For portability reasons, IBM recommends that you use application server variables to specify a relative path to the certificate revocation list. This recommendation is especially important when you are working in a WebSphere Application Server Network Deployment environment. For example, you might use the USER_INSTALL_ROOT variable to define a path such as $USER_INSTALL_ROOT/mycertstore/mycrl where mycertstore represents the name of your certificate store and mycrl represents the certificate revocation list. For a list of the supported variables, click Environment > WebSphere variables in the administrative console. The following list provides recommendations for using CRLs:

• If CRLs are added to the collection certificate store collection, add the CRLs for the root certificate authority and each intermediate certificate, if applicable. When the CRL is in the certificate collection store, the certificate revocation status for every certificate in the chain is checked against the CRL of the issuer.

• When the CRL file is updated, the new CRL does not take effect until you restart the Web service application.

• Before a CRL expires, load a new CRL into the certificate collection store to replace the old CRL. An expired CRL in the collection certificate store results in a certificate path (CertPath) build failure.
