<p>This function prepares to obtain credentials matching <em>creds</em> , either by retrieving them from <em>ccache</em> or by making requests to ticket-granting services beginning with a ticket-granting ticket for the client principal’s realm.</p>
<p>The resulting TGS acquisition context can be used asynchronously with krb5_tkt_creds_step() or synchronously with krb5_tkt_creds_get(). See also krb5_get_credentials() for synchronous use.</p>
<p>Use krb5_tkt_creds_free() to free <em>ctx</em> when it is no longer needed.</p>
