Samba Password Encryption vs. C209

[Andrew Edem]

C208 (CAE Specification) Protocols for X/Open PC Interworking: SMB,
Version 2 says that lan manager passwords should be encrypted against a
string of eight question marks, then encrypted against the challenge key
presented by the server, yet samba encrypts the password against
"\x4B\x47\x53\x21\x40\x23\x24\x25".

Secondly, the DES routines in Samba seem to vary from the other
algorithms I've seen. (I'm assuming these are either related, or the
X/Open standard is VERY off.)

I guess I'm wondering why Samba differs from the standard.

Thanks,
