I call it dirty because I allowed anonymous access to the NFS share. I tried the UID mapping thing but could not get it to work properly for multiple reasons. They had not enabled the NFS extensions in AD, so I could not use the AD authentication. The “unmapped UNIX user access” option worked only for giving access to the NFS share to only one Solaris server. Other Solaris servers could not write to the same share. Hence I broke down and enabled anonymous access. So here is how to create a quick NFS share for allowing your Solaris brothers to send data to your Windows world.
