I would like to add that the mount will use the userid of the activating 
user, but that the smbclient does a guest
lookup. It is with this construction not possible to make use of this 
"activating userid" in auto.smb. In general I find it very difficult to 
figure out a construction which does support mounting for every ordinary 
user which:
- give enough permissions so that user one cannot access other users 
mountpoint (if more than one user is logged in)
- use the activating user in the mount program as the lookup program as well
