Issue/Introduction

• While configuring Windows Backup path in the NSX manager using newly created service accounts, the following error is encountered:
  “Authentication failed on fileserver sftp://IP/backup (Error Code: 29115).”
  
• Existing user accounts are able to successfully configure and perform backups without any issues. The newly created service accounts are able to log in successfully and do not have expired passwords or account lockouts.
• When attempting to execute SFTP commands via the CLI using these newly created accounts, the thumbprint can be successfully retrieved; however, access to the destination fails with a “permission denied” error.
