+https://msdn.microsoft.com/en-us/library/cc237957.aspx
+The KDC will use the long-term key that the KDC shares with the server, so that the server can verify this signature on receiving a PAC.
+The server signature is a keyed hash [RFC4757] of the entire PAC message, with the Signature fields of both PAC_SIGNATURE_DATA structures set to zero.
+The key used to protect the ciphertext part of the response is used.
+The checksum type corresponds to the key unless the key is DES, in which case the KERB_CHECKSUM_HMAC_MD5 key is used.
+The resulting hash value is then placed in the Signature field of the server's PAC_SIGNATURE_DATA structure.

+KDC Signature (SignatureType = 0x00000007)

+The KDC will use KDC (krbtgt) key [RFC4120], so that other KDCs can verify this signature on receiving a PAC.
+The KDC signature is a keyed hash [RFC4757] of the Server Signature field in the PAC message.
+The cryptographic system that is used to calculate the checksum depends on which system the KDC supports, as defined below:
+- Supports RC4-HMAC --> KERB_CHECKSUM_HMAC_MD5
+- Does not support RC4-HMAC and supports AES256 --> HMAC_SHA1_96_AES256
+- Does not support RC4-HMAC or AES256-CTS-HMAC-SHA1-96, and supports AES128-CTS-HMAC-SHA1-96 --> HMAC_SHA1_96_AES128
+- Does not support RC4-HMAC, AES128-CTS-HMAC-SHA1-96 or AES256-CTS-HMAC-SHA1-96 --> None. The checksum operation will fail.
