+ * Get a Kerberos service ticket to use as the base of an rxkad token for
+ * a given AFS cell.
+ *
+ * @param[in] context
+ * An initialized Kerberos v5 context
+ * @param[in] realm
+ * The realm to look in for the service principal. If NULL, then the
+ * realm is determined from the cell name or the user's credentials
+ * (see below for the heuristics used)
+ * @param[in] cell
+ * The cell information for the cell to obtain a ticket for
+ * @param[out] v5cred
+ * A Kerberos credentials structure containing the ticket acquired
+ * for the cell. This is a dynamically allocated structure, which
+ * should be freed by using the appropriate Kerberos API function.
+ * @param[out] realmUsed
+ * The realm in which the cell's service principal was located. If
+ * unset, then the principal was located in the same realm as the
+ * current user. This is a malloc'd string which should be freed
+ * by the caller.
+ *
+ * @returns
+ * 0 on success, an error value upon failure
+ *
+ * @notes
+ * This code tries principals in the following, much debated,
+ * order:
+ *
+ * If the realm is specified on the command line we do
+ * - afs/cell@COMMAND-LINE-REALM
+ * - afs@COMMAND-LINE-REALM
+ *
+ * Otherwise, we do
+ * - afs/cell@REALM-FROM-USERS-PRINCIPAL
+ * - afs/cell@krb5_get_host_realm(db-server)
+ * Then, if krb5_get_host_realm(db-server) is non-empty
+ * - afs@ krb5_get_host_realm(db-server)
+ * Otherwise
+ * - afs/cell@ upper-case-domain-of-db-server
+ * - afs@ upper-case-domain-of-db-server
