Some NFS servers support an auxiliary NFSv3 ACL protocol that
|
|
|
|
|
Sun added to Solaris but never became an official part of the
|
|
|
|
|
NFS version 3 protocol. This protocol extension allows
|
|
|
|
|
applications on NFS clients to manipulate POSIX Access Control
|
|
|
|
|
Lists on files residing on NFS servers. NFS servers enforce
|
|
|
|
|
ACLs on local files whether this protocol is available or not.
|
|
|
|
|
|
|
|
|
|
Choose Y here if your NFS server supports the Solaris NFSv3 ACL
|
|
|
|
|
protocol extension and you want your NFS client to allow
|
|
|
|
|
applications to access and modify ACLs on files on the server.
|
|
|
|
|
|
|

Most NFS servers don't support the Solaris NFSv3 ACL protocol
|
|

|
extension. You can choose N here or specify the "noacl" mount
|
|
|

option to prevent your NFS client from trying to use the NFSv3

|
ACL protocol.
