I played around with it some more.

With SecurityFlags = 0x7 (default) the server asks for a plaintext
password and the client refuses. That's fine.

With 0x37 the client agrees to send a plaintext password (or at least
fails to reject the server's request for one,) but actually sends:

< ANSI Password Length: 24
< Unicode Password Length: 24

< ANSI Password: 3577D3557009178AFF455A0F7A99C6585CAEF99C515F2F2C
< Unicode Password: 3577D3557009178AFF455A0F7A99C6585CAEF99C515F2F2C

(my password was aaaaaaaa). This fails with error -13 (invalid password.)

With 0x30 the client sends:

> Password Length: 24

> Password: 61616161616161610000000000000000681C1DCF00002200

and everything works.

That's OK then. I just happened to notice it when I was comparing
traces of smbfs mounts to the ones from cifs. Maybe the manpage should
mention this difference for those who are converting, though.
