Kerberos credential caches</a></h2>
krb5_ccache structure holds a Kerberos credential cache.<p>
Heimdal support the follow types of credential caches:<p>
<ul>
<li>SCC Store the credential in a database</li><li>FILE Store the credential in memory</li><li>MEMORY Store the credential in memory</li><li>API A credential cache server based solution for Mac OS X</li><li>KCM A credential cache server based solution for all platforms</li></ul>
