When you install an SSL certificate in ArcGIS Server, Portal, or the Data Store, should you delete the self-signed certificate when you are done?
Solved! Go to Solution.
Even if you have installed a valid SSL certificate, you should not delete the self-signed certificate from ArcGIS Server, Portal, or Data Store. Here's why.
Fallback Option:- The self-signed certificate is used as a backup in case your genuine certificate fails. It provides basic functionality within your ArcGIS environment for troubleshooting purposes.
Testing:- The self-signed certificate might be useful for testing your ArcGIS installation to ensure its functionality before setting a trusted certificate.
While you do not have to delete the self-signed certificate, you should ensure that it is not the active certificate used for secure connections. Here's what you should do instead.
Configure Valid Certificate:- To Configure ArcGIS Server, Portal, or the Data Store to utilize this certificate for safe connection after getting a valid SSL certificate from a reliable Certificate Authority
Disable Self-Signed:- To avoid unintentional use, you can disable the self-signed certificate in certain ArcGIS versions. This isn't necessarily required, though, and it might not be included in every edition.
