/** This test is intended to test trailing zeros in an auth value
 *
 * An primary key with an auth value with trailing zeros is created.
 * A key with this primary is parent is created.
 * Esys_TR_SetAuth which strips the zeros is calles.
 * The key is created again.
 * The creation of an session where an bind key with a trailing
 * zero in the auth value is tested.
 * A session where the owner hierarchy is used as bind key in
 * combination with Esys_HierarchyChangeAuth is tested.
 * An nv index with trailing zeros in the auth value with
 * trailing zeros in combination with Esys_NV_ChangeAuth
 * is tested.
 *
 * Tested ESYS commands:
 *  - Esys_Create() (M)
 *  - Esys_CreatePrimary() (M)
 *  - Esys_FlushContext() (M)
 *  - Esys_StartAuthSession() (M)
 *  - Esys_PolicyAuthValue() (M)
 *  - Esys_PolicyCommandcode() (M)
 *  - Esys_PolicyGetDigest() (M)
 *  - Esys_NV_DefineSpace() (M)
 *  - Esys_NV_Write() (M)
 *  - Esys_NV_Read() (M)
 *  - Esys_NV_UndefineSpace() (M)
 *  - Esys_NV_ChangeAuth() (M)

 * @param[in,out] esys_context The ESYS_CONTEXT.
