Deactivate Kerberos realm membership
IMPORTANT:
Make sure that local authentication is enabled and working properly
before leaving the Kerberos realm. If local authentication is still disabled
and the IPBS/IPBL is no longer a member of the realm it is not possible to
access the IPBS/IPBL in any other way.
1
Select General > Admin.
2
In the Delegated Authentication section clear the Disable local authentication check
box.
3
Click "OK".
To deactivate the Kerberos membership for a client, do the following:
1
Select General > Admin.
2
Go to the Kerberos section and click on the blue text link "Leave realm".
3
It is possible to deactivate Kerberos realm membership in two ways:
• Deregister: The client is removed from the server database.
In the
Leave Kerberos realm
window, enter the user name and password for a user
with administrator or join the realm account in the
Deregister with Kerberos server
section.
Click "Deregister".
• Delete: Leave the realm without removing data from the server.
Click "Delete".

Configure Automatic Firmware Update
The IPBS/IPBL can be configured to automatically update its firmware. A script file must be
uploaded to a suitable directory on an internal web server. For information on the script
file syntax, see
Appendix A:
How to Use the Update Server
on page 148.
1
Select General > Update
2
Enter the URL of the script file in the URL text field.
3
Enter the poll interval, in minutes, in the Interval (min) text field
4
Click "OK".
The Current Update Serials section shows the values of the variables set after the last
execution of the associated command.
8.1.5
Configure the NTP Settings
Since the IPBS/IPBL does not have a battery-backed real-time clock, the internal time will
be set to 0:00 hrs, 1.1.1970 in the case of a restart.
In order to get the correct time in the system, specify the IP address of a NTP time server.
The IPBS/IPBL will synchronize its internal clock to the time server at startup and at the
specified intervals. The clock is, for example, used by the handsets and log files.
