Unable to log into WebAccess Administration Console in GroupWise 2014.x or 18

Error:  Unable to connect to the GroupWise Admin Console @https://ipaddressorservername:9710/gwadmin-service/system/whoami

In GroupWise 2014 and 18 accessing the Webaccess Administration Console is different than previous versions of GroupWise

• The admin user is set in the webacc.cfg in versions prior to 2014, however the WebAccess Console in 2014.x and 18 above use the GroupWise Administration Console admin credentials
  
• The IP address that is configured for the WebAccess Console will now use the IP address of the Admin Service that the primary domain server rather than using the WebAccess IP address
  

1. Open the /var/opt/novell/groupwise/webaccess/webacc.cfg file or in Windows, C:\Novell\GroupWise\WebAccess\webacc.cfg
2. Locate the lines below, and update false to true and update 127.0.0.1 to the IP address of the MTA to be used
         Admin.WebConsole.enable=false
         Admin.RestService.host=IPAddress-Of-Webaccess-Server, not 127.0.0.1
         Admin.RestService.port=9710
         Note: If there is a hostname specified in the GroupWise Administration Console for the MTA TCP/IP Address settings, then the same hostname may need to be set in the webacc.cfg
   
3. Restart Tomcat by typing rctomcat6 restart for SLES, novell-tomcat6 restart for OES, or by going to services and restarting the tomcat service for Windows
   

If the same problem occurs after following the steps above, please do the following

1. Launch the GroupWise Administration Console
2. Select the settings for the MTA that is used in the webacc.cfg
3. Select the SSL Settings tab
4. Click Generate Certificate to create new self-signed certificates and enter a password if desired
5. Restart Tomcat by typing rctomcat6 restart for SLES, novell-tomcat6 restart for OES, or by going to services and restarting the tomcat service for Windows
