This is great! I am not against LDAP ACLs at all.

yes and if you do that it is in claer text. (on sarge an woody I tested that)

So you use tcpdump to get a clear text password.
With cipux you can use (only as root) cat.

If I understand you right, the idea is to use opposite of tcpdump to mystify
the storage of the password?

So the basic security bind samba is only chmod and chown on the filesystem, as 
I said.

So do we have a security problem also with samba?

My assumption in the past was, that samba was set up in a save way under skole 
and I do so exactly with CipUX. But every time I talk about implementation 
details i got complains about security. I appreciate this because it let us 
think about a good platform. 

So make samba save and we choose the same method for CipUX.

yes this is obvious.
