# Configure communication with the source server

Configure communication between PingDataSync and the Lightweight Directory Access Protocol (LDAP) *(tooltip: \<div class="paragraph">
\<p>An open, cross platform protocol used for interacting with directory services.\</p>
\</div>)* source servers with the `prepare-endpoint-server` tool. If user accounts do not exist, this tool creates the appropriate user account and its privileges. Also, because the source is an PingDirectory server, this tool enables the changelog.

|   | The `prepare-endpoint-server` tool can only be used on LDAP directory servers. For the SCIM server, manually create a sync user entry.Run the `prepare-endpoint-server` command to set up communication between PingDataSync and the source server(s). The tool will prompt for the bind distinguished name (DN) *(tooltip: \<div class="paragraph">&#xA;\<p>A name uniquely identifying an object within the hierarchy of a directory tree.\</p>&#xA;\</div>)* and password to create the user account and enable the change log. |
