The z/OS UNIX System Services Directory Default and File Default ACLs for this object do not match. Management of mismatched Directory and File Default ACLs is only supported between the z/OS NFS Client and the z/OS NFS Server. For other NFS Client/Server combinations, the z/OS Directory and File Defaults must match and z/OS File Default requests should be used for managing non-z/OS NFS ACLs. The conversion request cannot be processed.

On the z/OS NFS Server this could occur when the z/OS UNIX File and Directory Default ACL entries do not match. z/OS NFS does not support remote management of such ACLs.

On the z/OS NFS Client this can occur when the Directory Default does not match the remote system's existing Default ACLs. Most non-z/OS platforms only have a single set of Default ACLs, not separate File and Directory Default ACLs. Therefore, z/OS NFS ACL management support uses the File Default ACL requests to manage the NFS Default ACLs. To avoid potential errors, in this scheme, Directory Default ACL requests are not supported.
