Hi there,
If you’ve installed OpenSSO Enterprise 8.0 on Glassfish, you may have the following problem:
- After installation of OpenSSO, you try and login.
- Using the correct username and password you are redirected back to the login screen.
The fix is to add the line
-Dcom.iplanet.am.cookie.c66Encode=true
As a JVM option in Glassfish, when changing the other JVM options (like -client to -server).
