Enabling CRLs

Identify the certificate revocation lists (CRLs) that define a list of digital certificates which have been revoked. Revoked certificates should not give the Sybase Unwired Platform device user access to the Unwired Server runtime.

Administrators can configure certificate revocation lists (CRLs) to check if any of the certificates in the path are revoked. A series of URIs define the CRL location.

  1. Using Sybase Control Center, open the CertificateAuthenticationLoginModule and CertificateValidationLoginModule used by your security configuration.
  2. For the CRL property, define one or more URIs. If using multiple URIs, each must be indexed.
    The index number used determines the order in which CLRs are checked. This example uses two URI, each indexed accordingly so that the Verisign CRL comes first.
    crl.1.uri=http://crl.verisign.com/ThawtePersonalFreemailIssuingCA.crl
    crl.2.uri=http://crl-server/

Note: While CRL applies to a particular login module, OCSP determines certificate status server-wide. Administrators must edit the %JAVA_HOME%/jre/security/java.security file to enable OCSP. Then in the login modules, set the Enable Revocation Checking property to true. For information, see Enabling OCSP.
