decryption problem with enctype 7500

[lily~hashcat]

I find that if I change the value of the "user", "realm" and "salt" at will in hash1, it can still be decryted successfully. So there are two another questions. First, does the decryption of kerberos enctype 23 need a salt? Second, If it needs a salt, where can I find it in the kerberos AS-REQ package?
