IT34143: WINDOWS FILE SYSTEM BACKUP ONLY SUPPORTS NTLMV2 AND REFUSE LM, NTLM

APAR status

• Closed as documentation error.

Error description

• The manual needs to be updated to state that NTLM is not
  supported by updating the requirements section for the File
  System backup feature:
  Example:
  Group Policy Object
  For the Network security: "LAN Manager authentication level
  policy"
   setting at "Computer Configuration > Windows Settings >
  Security Settings > Local Policies > Security Options",
   specifies one of the following options:
  
  Not Defined.
  -Send NTLMv2 response only.
  -Send NTLMv2 response only. Refuse LM.
  -Send NTLMv2 response only. Refuse LM & NTLM.
  The Send
  "NTLM response only" option is not compatible with the vSnap
  Common Internet File System (CIFS) and SMB version and can
  cause CIFS authentication problems.
  
  You can specify the Group
  Policy Object (GPO) setting by navigating to:
  
  "Computer Configuration > Policies > Windows
  Settings > Security Settings > Local Policies
  > Security Options > Network security:
  Restrict NTLM: Incoming NTLM" traffic
  Or
  
  "Computer Configuration > Policies >
  Windows Settings > Security Settings
  > Local Policies > Security
  Options > Network security:
  Restrict NTLM: Outgoing NTLM! traffic
  and choose one of the
  following options:
  
  -Allow all
  -Allow all accounts
