<div dir="ltr"><p>Thanks Gordon for your reply!</p>
<p>The issue got fixed after installing the latest release of SQL Server Native Client. Turns out the error was caused by an older minor release (from 2012).</p>
<p>It seems that the latest version of the Native Client actually works with TLS 1.2, even though it’s not officially documented and the Native Client is no longer supported by Microsoft.</p>
<p>Thanks again for the tip</p></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">Il giorno mer 29 ott 2025 alle ore 16:43 Gordon Luckett <<a href="mailto:gordon.luckett@arrowgeomatics.com">gordon.luckett@arrowgeomatics.com</a>> ha scritto:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">You may just need to replace the v11 SQL Server Native Client with the ODBC/OLEDB one:<br><a href="https://learn.microsoft.com/en-us/sql/connect/oledb/oledb-driver-for-sql-server?view=sql-server-ver15" target="_blank">https://learn.microsoft.com/en-us/sql/connect/oledb/oledb-driver-for-sql-server?view=sql-server-ver15</a><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Oct 29, 2025 at 10:25 AM Riccardo Pucci via mapguide-users <<a href="mailto:mapguide-users@lists.osgeo.org" target="_blank">mapguide-users@lists.osgeo.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><p>Hi everyone, and congrats to Jackie for the 4.0 release!</p>
<p>I’m still on MapGuide 3.1.2 and I’ve run into a problem after upgrading an MSSQL database to version 2019.<br>
The server only allows TLS 1.2, and when MapGuide tries to connect we get the following error:</p>
<p>org.osgeo.mapguide.MgFdoException: An exception occurred in FDO component.<br>
Error occurred in Feature Source (Library://GW/data/PMA_DATI_GW_sql_all.FeatureSource): An exception occurred in FDO component.<br>
RDBMS: [Microsoft][SQL Server Native Client 11.0]Encryption not supported on the client.<br>
[Microsoft][SQL Server Native Client 11.0]SSL Provider: The client and server cannot communicate, because they do not possess a common algorithm.<br>
[Microsoft][SQL Server Native Client 11.0]Client unable to establish connection.</p>
<p>Has anyone else run into this? Unfortunately we can’t upgrade to 4.0 right away, and enabling TLS 1.1 on the server isn’t an option.</p>
<p>Thanks!</p></div><div>Riccardo</div><span class="gmail_signature_prefix">-- </span><br><div dir="ltr" class="gmail_signature"><div dir="ltr"><div><font face="courier new, monospace">Riccardo Pucci</font></div><div><span style="color:rgb(0,0,0);background-color:rgb(245,245,245)"><font face="courier new, monospace">Geoweb Italia S.r.l.</font></span><br></div></div></div></div>
