Here are the instructions. As I understand, you already have a certificate that you wish to put into SysAid (and not create a self-signed certificate). If that's indeed the case, you should read the instructions on Apache Tomcat's site (link below).
To configure SSL encryption (https) for SysAid, you must first create a keystore file (which acts as the certificate). If you wish to use a purchased certificate or just one from your own CA, please consult the guide on Apache's website at https://jakarta.apache.org/tomcat/tomcat-4.1-doc/ssl-howto.html
To create a keystore file, please use the following command:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA
This will create a “.keystore” file in your C:\Documents and Settings\CURRENT-USER\ folder. Please copy this file to your ...\SysAidServer\ folder.
When creating this file, you should use the password "changeit" for both passwords
The next step would be to edit ...\SysAidServer\tomcat\conf\server.xml file. Please add the below text right after the existing <Connector> tag:
<!-- Define an SSL HTTP/1.1 Connector on port 8443 -->
<Connector className="org.apache.catalina.connector.http.HttpConnector" port="8443" minProcessors="5" maxProcessors="75" enableLookups="true" redirectPort="443" acceptCount="10" debug="0" scheme="https" secure="true">
<Factory className="org.apache.catalina.net.SSLServerSocketFactory" clientAuth="false" protocol="TLS" keystoreFile="C:\Program Files\SysAidServer\.keystore"/>
port=”8443” represent the port SysAid will be listening on for secure connections. In this case you will have to use the following URL: https://SERVER-NAME:8443/
After these changes were made, please restart the SysAid Server service and check if SysAid is accessible over a secure connection.
