After configuring AEM Forms 6.3 SPNEGO, I get this message in my browser "authenticated=true&authstate=COMPLETE&assertionid=51CC39AC-2EF0-D543-4BE0-FDED500AD5D8&authtype=SSO." I am using IE 11.0.47. This is the link that use http://my.org.address:8080/um/login?um_no_redirect=true, and the server log displays the message below:
11:30:59,033 INFO [com.wedgetail.idm.sso.util.CommonsSsoLogger] (http-/0.0.0.0:8080-4) Session ID: fGBD9PSwFgqPIev-EVgf2-Jx Request: /um/login Remote: xx.xx.xx.xx Principal: SPNEGOACCOUNT@MY.ORG.ADDRESS Message: Client successfully authenticated 11:30:59,034 INFO [com.wedgetail.idm.sso.util.DefaultAuditor#access] (http-/0.0.0.0:8080-4) access: /um/login by user: ANYUSER = granted.
This is my last step to migrate from LiveCycle ES4 to AEM Forms 6.3. Thank you.
The URI um/login?um_no_redirect=true is only for testing and since you go a message that client successfully authenticated, the test has passed. Also, if you are logged in via sso using /lc/ws, the sso is working fine. I think your system is setup fine for sso.
