It is my understanding that Samba handles the conversion between unix semantics and windows. NFS has been reportedly unreliable with Cyrus but I would think that Samba should work fine since it has a sort of local cache mechanism built into it.
I am not 100% sure of how Samba works or if the semantics would be handled... anybody know for sure? - Drew On Wed, 22 Sep 2004 07:51:57 -0400, David Base <[EMAIL PROTECTED]> wrote: > > I tried doing something similar to this using Sharity instead of Samba (SMBclient > is not available in Solaris), i.e., mounting a shared Windows 2000 folder via NFS > on a Solaris box.
