Hello,

OK - the second part of the problem solved now (with RO access to NFS 
shares).
I was, of course, wrong, thikning (and writing), that the UID were the same.
I forgot to force setting the UID to the particular value at the 
OpenIndiana user creation stage,
so it was set automatically.
After fixing the UID of my local OpenIndiana user, the problem has 
dissapeared, and I have RW access
to the NFS shares.

However - the first part of the problem still exists. It seems that NWAM 
tries to activate the NIC
a bit too late ...
