5Go to the Authentication Se
rvers section.
6In the Realm/Domain
text field, enter the realm name specified in the Kerberos
server.
7In the Address
text field, enter the IP address of the Kerberos server. In the Kerberos
server enter 127.0.0.1 (localhost) as the IP address. The Port and the Admin Port
text fields are filled out automatically with default ports. Note: If other than default
ports are used, in the text fields replace the default ports with the other ports.
8In the Seco
ndary Address text field, enter the IP address of the secondary Kerberos
server. In the secondary Kerberos server enter 127.0.0.1 (localhost) as the IP
address. The Secondary Port and the Secondary Admin Port text fields are filled out
automatically with default ports. Note: If other than default ports are used, in the
text fields replace the default ports with the other ports.

Log in using Kerberos
1 Make sure that secure HTTPS protocol is used when logging in.
2 Login on the client using a server account. When prompted for user name, the
n
ame of the realm has to be entered in front of the user name, separated by a
backslash in the following way: REALM\username or username@REALM.
Disable local authentication
It is recommended to disable
local authentication after Kerberos authentication is
configured. It provides additional security and it is much easier to change the password of
a user account or delete a compromised user account on the Kerberos server than
changing the local user accounts on each IPBS/IPBL.
IMPORTANT: Make
sure that the Kerberos authentication is working properly before
disabling local authentication. If the Kerberos authentication is not
working and local authentication is disabled it is not possible to access the
IPBS/IPBL in any other way.
1In the Delegat
ed Authentication section select the Disable local authentication
check box.
2 Click "OK".
Configure cross-realm authentication
Cross-realm authentication is used to authent
icate users from another trusted realm. In
this way it is possible for IP-DECT users to login to the IPBS/IPBL using their Windows user
name and password in the Active Directory (AD). Security policies of the AD can then be
used in IP-DECT. The trust relationship between the two realms is confirmed by
configuring a shared password on both servers in the realms. This password is used to
encrypt communication between the realms. To configure cross-realm authentication, do
the following:
Requirements for IPBS1, IPBS2 and IPBL:
• Software version 6.1.X and later
• NTP configured
