[cifs-protocol] RE: CreateTrustedDomainEX blob incorrect

[Richard Guthrie]

Andrew,

I have attached an updated MS-LSAD document that contains a revised text for section 2.2.58.  The highlighted text is what we have added to make this structure more clear on how to parse it.  In order to successfully parse this structure you need to use the values in

1.      Outgoing authentication information size
2.      Incoming authentication information size

These values tell you the size of incoming and outgoing authentication information.  Outgoing buffer is always before incoming.  Once you have the buffer for outgoing and incoming authentication information the offsets for current and previous LSAPR_AUTH_INFORMATION will make sense.

Please review the documentation and let us know if you have further questions.

I'm sorry, I can't see how the changed PDF indicates this, nor how an implementation should tell if these are not included.

Sorry,
