That would be a good addition to Ganesha. Look at the NFSv4 ACL code for thoughts on how to do the caching. Also FSAL/access.c will need to be updated to do POSIX ACL permission checking.
If you are interested in NFSv4, you may also want to do the conversion between POSIX ACLs and NFSv4 ACLs.

Subject: [NFS-Ganesha-Devel] Regarding POSIX ACL support
In the kernel nfs-server(Linux), the NFSACL sideband protocol is implemented to provide POSIX ACL for NFS v3.
Currently, the NFSACL sideband protocol isn't supported in the nfs-ganesha server.
We plan to implement this sideband protocol in the nfs-ganesha and push to nfs-ganesha community.
Any suggestions?
