|

|
|
+Assume no extended access control mechanisms like POSIX ACLs are used
|
||
|
|
+on the NFS filesystem, and depend on the file mode permission bits
|
||
|
|
+instead of using the ACCESS remote procedure call. The default is to
|

|
|
+use the ACCESS remote procedure call for making access decisions in
|

|
|
+NFS version 3. (On NFS version 2 filesystems this option has no effect.)
|
||
|
|
+This option also deactivates the GETACL and SETACL remote procedure calls
|
||
|
|
+which are otherwise used to manipulate ACLs.

All of the non-value options have corresponding nooption forms.
