Connecting to a DS-Client
A DS-Client performs logon validation (for DS-User sessions) with the local or domain user account database (if applicable).
•	For Windows DS-Clients, by default, only administrators or backup operators are allowed access to DS-Client.
•	For Linux and Mac DS-Clients, root users are allowed access to the DS-Client by default.
An administrator can configure different user and group roles to access a DS-Client. A DS-Client allows multiple simultaneous connections with the same or different authentication credentials. See 
“Configuring the user and group settings”.
NOTE:  DS‑Client uses the DS‑User credentials as default credentials for network resources when creating new backup sets.
You can connect to a specific DS-Client on your network by selecting it from a list. Each DS-Client in the list is color coded as follows:
 
Table 2	DS-Client color coding information
| Color | RGB values | Description | 
| BLUE | (0, 0, 255) | The DS-Client runs on the local machine on which the DS-User is installed. (Supersedes other colors. Only DS-Client can appear blue.) | 
| BLACK | (0, 0, 0) | FullFeatured DS-Client (Windows / Linux / Mac) | 
| GREEN | (0, 153, 0) | Uninitialized DS-Client. | 
| LIGHT BLUE | (40, 120, 220) | DS-Mobile Client (Windows) | 
| AQUA | (20, 170, 170) | DS-Notebook Client (Mac) | 
| RED | (255, 0, 0) | DS-Client Service is not running. | 
To connect to a DS-Client:
1.	Start the DS-User application.
2.	Select a DS‑Client from the list on the left side of the main window. To switch between computer names and IP addresses, right-click the list. The Connect to DS‑Client Service dialog box appears.
3.	In the Protocol box, select one of the following protocols:
•	Encrypted: All the data between the DS-User and the DS-Client will be encrypted with a random encryption key at every connection.
•	Standard: This option is only offered for backwards compatibility with old service/daemon versions that do not have this feature.
4.	Under Credentials, type your credentials, and then click Connect.
