[cifs-discuss] Username case sensitivity in cifs authentication

[Afshin Salek]

Usernames in workgroup mode are c-s since they have to correspond to
a Solaris user. One thing we can perhaps do to make this work better
is to always lower case the username we receive from Windows before
looking up smbpasswd (since Solaris usernames are usually all lower
case). We should perhaps preserve the username case in smbd message.

I'll file a CR for this.
