Please refer below wiki page for step by step instructions to generate and import certificates into "ssa.jks" on SOI Manager and UI
Once the certificate is imported into ssa.jks, you may run below command to list the certificates. By default, there is 1 certificated named "tomcat" for SOI Manager.
keytool.exe -list -v -keystore "C:\Program Files (x86)\CA\SOI\SamUI\conf\ssa.jks"
keytool.exe -list -v -keystore "C:\Program Files (x86)\CA\SOI\tomcat\conf\ssa.jks"
When it prompts for password, enter "catalyst"
Note: Please backup original ssa.jks before importing any certificate.
You may run above commands to list the certificates on UI server and see if the old certificate exists
