[Samba] ls and getfacl hanging with nt authentication

[Spaceboy]

I have Samba 3.0.2a running on Solaris 8 compiled with winbind and 
authenticating against an NT domain.

every time I run a "ls -l" or "getfacl" the command line hangs as it's 
tries to pull down all the user/group details from the domain.

I heard this may have something to do with nscd (nameservice cache 
daemon?) which is running on the solaris machine.

Any thoughts appreciated!
