Power BI Report Server (PBI RS) uses the Lightweight Directory Access Protocol (LDAP) to communicate with the local Active Directory (AD) for authentication and authorization purposes.

If you want to use LDAPS (LDAP over SSL) instead of LDAP, you will need to make changes to the configuration settings of PBI RS and your local AD. Here are the general steps:

  1. Obtain a valid SSL certificate from a trusted certificate authority (CA) for your AD domain.

  2. Install the SSL certificate on your AD domain controller.

  3. Configure your AD domain controller to use LDAPS by modifying the LDAP server settings in the AD Domain Services configuration.

  4. In PBI RS, change the connection string in the PBIRS configuration file (RSReportServer.config) to use the LDAPS protocol. This can be done by replacing "LDAP" with "LDAPS" in the connection string.

  5. Restart the PBI RS service to apply the changes.

It's important to note that the above steps are just a general guide, and the exact steps may vary depending on your specific environment and the version of PBI RS you are using.

It's highly recommended to test the changes in a development environment before applying to a production environment and make sure that the certificate that you are using is valid, and the communication between the PBI RS and the AD is secure.

Tell me please, where in the file RSReportServer.config i can find and replace this parameters? 

I can't see it ;(

i have Power BI report Server 15.0.1107.116

In the Power BI Report Server, the configuration settings can be found in the file "RSReportServer.config" which is typically located in the following directory:

C:\Program Files\Microsoft SQL Server\MSRSXX.XX\Reporting Services\ReportServer

The settings related to the communication with the local Active Directory can be found in the "<AuthenticationTypes>" section of the RSReportServer.config file. You can replace the "LDAP" value with "LDAPS" in the "<AuthenticationTypes>" section to configure the PBI RS to use LDAPS.

Here is an example of the relevant section of the RSReportServer.config file:


<RSWindowsNegotiate />
<RSWindowsNTLM />
<RSWindowsBasic />


Please note that changing the RSReportServer.config file can affect the behavior of your report server. It is recommended to make a backup of the file before making any changes, and to thoroughly test the changes before deploying them to a production environment.

hello sir, i have an error is when i changed config
