ONTAP 9

Issue

  • Accessing home directories via NFS on Ubuntu clients experience permission denied errors when attempting to execute files. 
  • The issue occurs when the UNIX user’s LDAP “uid” matches the AD “UPN” but does not match the AD “sAMAccountName”. 
  • ONTAP fails to map the UNIX user to the corresponding Windows account, resulting in missing execute permissions and unsuccessful access.
  • log output:

[11] Could not find Windows name 'XXX\\XXXX'
**[11] FAILURE: Name mapping for UNIX user 'XXX' failed. Explicit Mapping failed and no default mapping found
Error: command failed: Failed to get user credentials. Reason: "SecDError: The mapped user does not exist and no default user is defined".
