SeDiskOperatorPrivilege

  • To configure share permissions, you need an account with „SeDiskOperatorPrivilege“. To grant this privilege, e. g. to the „Domain Admin“ group, run the following command on your AD member server(s):

# net rpc rights grant 'SAMDOM\Domain Admins' SeDiskOperatorPrivilege -U'SAMDOM\administrator' -I dc1.samdom.example.com

 

Existing privileges can be reviewed by

# net rpc rights list accounts -U'SAMDOM\administrator' -I dc1.samdom.example.com
 

Examples:
