User authentication with directory services
In in-house networks, the user accounts of different users are often administrated by
a directory service. The device can access such a directory service and authenticate
users against the directory service.
The directory service is exclusively used to authenticate a user. The user rights are
assigned within a database of the KVM system. The following paragraphs describe the
different scenarios:
 The user account exists within the directory service and the KVM system
The user can log in with the password stored in the directory service. After the
login, the user is assigned with the rights of the correspondent account in the
KVM system.
 The user account exists within the directory service, but not within the KVM system
A user that has been successfully authenticated against the directory service, but
does not have an account of the same name within the database of the KVM sys-
tem, is assigned with the rights of the RemoteAuth user.
If required, change the rights of this particular user account to set the rights for
users without a user account.
 The user account exists within the KVM system, but not within the directory service
If the directory service is available, it reports that the user account does not exist.
The access to the KVM system is denied to the user.
If the server is not available, but the fallback system is active (see below), the user
can log in with the password that is stored within the KVM system.
NOTE: If the Admin user account cannot be authenticated by the directory service,
the user account is authenticated by the device’s data base.
NOTE: The password which the user used to log in, is taken over into the data-
base of the KVM system.
ADVICE: Deactivate the RemoteAuth user to prevent users without user accounts
to log in to the KVM system.
IMPORTANT: Mind the following safety instructions to prevent a locked or deac-
tivated user from logging in to the system in case the connection to the directory
service fails:

If a user account is deactivated or deleted in the directory service, this action
can also be carried out within the user database of the KVM system.
 Only activate the fallback system in reasonable exceptional cases.
