	Thank you very much for replying to my post Luke.
I am already using the auto.home  NIS map in all of our systems and I have used 
the nis homedir = Yes flag as well. What I do not understand is why would we 
have to use samba on _every_ host in the automounter entries. Shouldn't samba 
deny access to untrusted hosts?

Suppose the following :

3 Solaris machines... 1,2 & 3

If 1 is running an automounter , then 2 can mount from 1 no prob as long as it 
is allowed to export the filesystem. Now, if 3 wants to mount that same 
filesystem that 2 is mounting from 1, but being served by the 2 machine, the 
cross mount will not work.

So, shouldn't samba by default not mount a filesystem that is not explicitly 
exported as a local filesystem on a machine the server is running on?

I set guest ok = no , and I can still mount \\A\root . As far as compilation is 
concerned, GUESTACCOUNT = nobody like default on the Makefile. One more thing...
In this distribution, people with the acc compiler will experience some internal 
compiler errors; therefore, not being able to compile...An easy and necessary 
workaround is to disable FLAGS1 in the Makefile or any other optimization flag 
they may be using.... ( Found out the hard way ).

Thank you for this tip Luke,
