After running a vulnerability scanning tool, the resulting report shows that my PAM server is affected by the "TLS Server Supports TLS version 1.0" vulnerability.
PAM was configured to allow TLS 1.0 and 1.1 connections.
Open the PAM Client and verify if the setting 'TLS v1.0/1.1 Connection Allowed' is Enabled or Disabled in the 'Access' tab of the 'Configuration / Security / Access" pane.
After disabling it and rerunning the test the "TLS Server Supports TLS version 1.0" vulnerability did no longer appear.
