13117149 – Accented Characters in Active Directory User Names

3.1.13. 13117149 – Accented Characters in Active Directory User Names

Problem: Active Directory authentication fails for user names that contain accented characters, such as

the German umlaut character (ü). The issue has been seen when using Windows Server 2003 R2.

The following error is shown in the log output when using the server/login/info log filter:

javax.security.auth.login.LoginException: Integrity check on decrypted field failed (31)

Cause: Active Directory authentication uses the Kerberos authentication protocol. This is a known issue

when Kerberos authentication is configured to use DES encryption.

Solution: The workaround is to disable the use of DES encryption in the krb5.conf Kerberos

configuration file on the SGD server.

Include the following lines in the [libdefaults] section of the krb5.conf file.

[libdefaults]

default_tgs_enctypes = rc4-hmac des3-cbc-sha1 aes128-cts aes256-cts

default_tkt_enctypes = rc4-hmac des3-cbc-sha1 aes128-cts aes256-cts

3.1.14. 13354844, 14032389, 13257432, 13117470 – Display Issues on Ubuntu

Client Devices

Problem: The following display issues might be seen on client devices running Ubuntu Linux.

• The kiosk mode minimize button does not work if you are not using a window manager or if you are

using a minimalist window manager, such as evilwm.

• The button for toggling between kiosk mode and an Integrated Window display does not work.

• The SGD Client task bar icon is not shown when using the Unity desktop.

• A seamless windows application that should span multiple monitors is instead displayed with scroll bars

on a single monitor.

Cause: Known issues when using a Ubuntu Linux client device.

Solution: Use one of the following workarounds.

• To use the kiosk mode window decoration, the window manager must implement the change state

protocol from Normal to Iconify. Ensure that you are running a suitable window manager.

• Use the Ctrl+Alt+Break keyboard shortcut to toggle between kiosk mode and an Integrated Window

display.

• To show the SGD Client task bar icon, add the SGD Client application to the whitelist for the Unity

desktop.

Start the dconf-editor and go to the Desktop → Unity → Panel dialog. Add Oracle Secure Global

Desktop to the list of applications.

• There is no known solution for the seamless windows issue on multiple monitors.
