GroupWise 18

SUSE Linux Enterprise Server 15


When trying to generate certificate in the GroupWise admin console for GroupWise agents getting error:

* Remote resource ( <server info> ) returned error: class cannot be cast to class ( and are in unnamed module of loader 'app')


This issue has been reported to engineering. A workaround to get the agents to use SSL is to create a self-signed certificate manually at the command line:

1. Make a new directory i.e. /root/certs

2. Change to the new directory

3. Using openssl, create a self signed cert and key. 
TID on creating self-signed certificates:

4. In the GroupWise admin console, go to the POA object > SSL tab > and point to the newly created directory where the self-signed certificates are located then save.

5. Restart agent 

NOTE: If a passphrase was set on the certificate/key in step 3 then the same passphrase will need to be set in GroupWise. In the GroupWise admin console > POA object > SSL tab under "Set Password"
