Example 7 with Config

Example 8 with Config

use of sun.security.krb5.Config in project jdk8u_jdk by JetBrains.

the class KDC method writeKtab.

/**
     * Writes or appends keys into a keytab.
     * <p>
     * Attention: This is the most basic one of a series of methods below on
     * keytab creation or modification. All these methods reference krb5.conf
     * settings. If you need to modify krb5.conf or switch to another krb5.conf
     * later, please call <code>Config.refresh()</code> again. For example:
     * <pre>
     * kdc.writeKtab("/etc/kdc/ktab", true);  // Config is initialized,
     * System.setProperty("java.security.krb5.conf", "/home/mykrb5.conf");
     * Config.refresh();
     * </pre>
     * Inside this method there are 2 places krb5.conf is used:
     * <ol>
     * <li> (Fatal) Generating keys: EncryptionKey.acquireSecretKeys
     * <li> (Has workaround) Creating PrincipalName
     * </ol>
     * @param tab the keytab file name
     * @param append true if append, otherwise, overwrite.
     * @param names the names to write into, write all if names is empty
     */
