# Adding your LDAP and OS servers
<a name="agentless-collector-gs-database-analytics-collection-add-servers"></a>

The database and analytics data collection module uses LDAP in Microsoft Active Directory to gather information about the OS, database, and analytics servers in your network. *Lightweight Directory Access Protocol (LDAP)* is an open standard application protocol. You can use this protocol to access and maintain distributed directory information services over your IP network.

You can add an existing LDAP server into your database and analytics data collection module to automatically discover OS servers in your network. If you don't use LDAP, you can add OS servers manually.

**To add an LDAP server to your database and analytics data collection module**

1. Open the Agentless Collector console. For more information, see [Accessing the collector console](agentless-collector-gs-access-console.md).

1. Choose **View Database and analytics collector**, then choose **LDAP servers** under **Discovery** in the navigation pane.

1. Choose **Add LDAP server**. The **Add LDAP server** page opens.

1. For **Hostname**, enter the hostname of your LDAP server.

1. For **Port**, enter the port number that is used for LDAP requests.

1. For **User name**, enter the user name that you use to connect to your LDAP server.

1. For **Password**, enter the password that you use to connect to your LDAP server.

1. (Optional) Choose **Verify connection** to make sure that you added your LDAP server credentials correctly. Alternatively, you can verify your LDAP server connection credentials later, from the list on the **LDAP servers** page.

1. Choose **Add LDAP server**.

1. On the **LDAP servers** page, select your LDAP server from the list and choose **Discover OS servers**.

**Important**  
For OS discovery, the data collection module needs credentials for the domain server to run requests using the LDAP protocol.

The database and analytics data collection module connects to your LDAP server and discovers your OS servers. After the data collection module completes the OS servers discovery, you can see the list of discovered OS servers by choosing **View OS servers**.

Alternatively, you can add your OS servers manually or import the list of servers from a comma-separated values (CSV) file. Also, you can use the VMware vCenter Agentless Collector data collection module to discover your OS servers. For more information, see [Using the VMware data collection module](agentless-collector-gs-data-collection-vcenter.md).

**To add an OS server to your database and analytics data collection module**

1. On the **Database and analytics collector** page, choose **OS servers** under **Discovery** in the navigation pane.

1. Choose **Add OS server**. The **Add OS server** page opens.

1. Provide your OS server credentials.

   1. For **OS type**, choose the operating system of your server.

   1. For **Hostname / IP**, enter the hostname or IP address of your OS server.

   1. For **Port**, enter the port number that is used for remote queries.

   1. For **Authentication type**, choose the authentication type that your OS server uses.

   1. For **User name**, enter the user name that you use to connect to your OS server.

   1. For **Password**, enter the password that you use to connect to your OS server.

   1. Choose **Verify** to make sure that you added your OS server credentials correctly.

1. (Optional) Add multiple OS servers from a CSV file.

   1. Choose **Bulk import OS servers from CSV**.

   1. Choose **Download template** to save a CSV file that includes a template that you can customize.

   1. Enter the connection credentials for your OS servers into the file according to the template. The following example shows how you can provide OS server connection credentials in a CSV file.

      ```
      OS type,Hostname/IP,Port,Authentication type,Username,Password
      Linux,192.0.2.0,22,Key-based authentication,USER-EXAMPLE,ANPAJ2UCCR6DPCEXAMPLE
      Windows,203.0.113.0,,NTLM,USER2-EXAMPLE,AKIAIOSFODNN7EXAMPLE
      ```

      Save your CSV file after you add credentials for all your OS servers.

   1. Choose **Browse**, then choose your CSV file.

1. Choose **Add OS server**.

1. After you add credentials for all OS servers, select your OS servers and choose **Discover database servers**.
