Setting Description
Reset Admin Account Lock Counter After Determines how many hours the failed login
window lasts. The window is a period of time
starting with the first failed login attempt and during
which the system counts subsequent failed
attempts against the number allowed.
The counter resets to zero at the end of the window
(if the account is not locked because of failed
attempts) and after a successful login.
Enable External Authentication
You can set up external authentication through Active Directory for your G7500 system. When enabled,
you can access the system with an Active Directory account or the system’s local administrator
credentials.
Before you begin, make sure that you configure the Domain Name setting on the Network > Primary
Network > LAN Options page with your Active Directory domain.
The system can map only one Active Directory group to a given role.
Procedure
1. In the system web interface, go to Security > Global Security.
2. Go to Authentication.
3. Configure the following settings:
Setting Description
Enable Active Directory External Authentication Specifies whether to authenticate users with the
Active Directory server. When you enable Active
Directory authentication, users can log in to the
system with their network credentials using this
format: domain\user. With this format, users can
have accounts on multiple domains.
Active Directory Server Address Specifies the Active Directory server’s FQDN or IP
address. If you are using subdomains, append port
number 3268 as follows: ad.domain.com:
3268.
You can alternatively use RealPresence Resource
Manager as an Active Directory server and enter its
address here.
If you enable Always Validate Peer Certificates
from Server on the Certificates page, make sure
this value matches what is in the Active Directory
server certificate. For example, if you enter the
Active Directory server IP address here, but the
certificate only has the server’s FQDN, external
authentication fails.
