Reset a user's password from a supplied TGT (AoratoPw):

## renew
The **renew** action will build/parse a raw TGS-REQ/TGS-REP TGT renewal exchange using the specified /ticket:X supplied. This value can be a base64 encoding of a .kirbi file or the path to a .kirbi file on disk. If a /dc is not specified, the computer's current domain controller is extracted and used as the destination for the renewal traffic. The /ptt flag will "pass-the-ticket" and apply the resulting Kerberos credential to the current logon session.
Note that TGTs MUST be renewed before their EndTime, within the RenewTill window.

## changepw
The **changepw** action will take a user's TGT .kirbi blog and execute a MS kpasswd password change with the specified /new:X value. If a /dc is not specified, the computer's current domain controller is extracted and used as the destination for the password reset traffic. This is the Aorato Kerberos password reset disclosed in 2014, and is equivalent to Kekeo's misc::changepw function.

## s4u
The **s4u** action is nearly identical to Kekeo's **tgs::s4u** functionality. If a user (or computer) account is configured for constrained delegation (i.e. has a SPN value in its msds-allowedtodelegateto field), this action can be used to abuse access to the target SPN/server.
