Sun OpenSSO Enterprise 8.0 Release Notes

1793: Authentication fails with multi-byte character for org or module in query parameter

If you try to log in to the OpenSSO Console using the org or module parameter with characters that are not UTF-8, the login fails. For example: http://host:port/deployuri/UI/Login?module=Japanese-string&gx_charset=UTF-8

Workaround. Use UTF-8 URLencoding characters such as %E3%81%A6 instead of native characters.
