post /v9/storage/virtual-servers/{virtualServerId}/security-principal

Lookup a Windows security principal in the context of a virtual server. This allows the principal to be validated before it is applied to a security descriptor for a file system object, a member of a local security group or used when configuring the authentication for a CIFS/SMB file system share. Lookups may fail if the virtual server is not configured to communicate with a domain controller.

Note: Accepted parameter values may be restricted based on the virtual server access granted by the API key used for authentication.

Authentication: x_subsystem_user Api Key "X-Subsystem-User"

Authentication: x_subsystem_password Api Key "X-Subsystem-Password"

Authentication: api_key Api Key "X-Api-Key"

Authentication: basicAuth HTTP - basic scheme

Path parameters

virtualServerId required

Either the virtual server ID or the object ID of the virtual server
