 for example:    chmod -b -R 744 /ifs/data/newNFSfolder   Will erase the ACL (that's the -b flag) and replace with 744 as the POSIX mode bits. (-R is recursive and will execute the command down the directory tree)   This should clean up any inadvertent ACLs that exist out there in your UNIX only folders.
I ran ls -al and found that a folder that I planned to use for UNIX / NFS only  has an ACL with Windows ACEs for Active Directory groups.  How do I get rid of them?
