Issue

  • NFSv4 users that utilize NFSv4 ACLs can mount, but operations like LS hang
  • LDAP server 10.17.XX.XX:636 was in use, a "getxxbyyy" was issued for getpwbyuid, ONTAP could connect to the server, ONTAP could bind, the UID was found, but the GID was returned with an incompatible value, that caused the query to fail
  • EMS logs:
