What is a prerequisite when integrating a Cisco ISE server and an AD domain?

Explanation

Explanation

The following are the prerequisites to integrate Active Directory with Cisco ISE.

+ Use the Network Time Protocol (NTP) server settings to synchronize the time between the Cisco ISE server

and Active Directory. You can configure NTP settings from Cisco ISE CLI.

+ If your Active Directory structure has multidomain forest or is divided into multiple forests, ensure that trust

relationships exist between the domain to which Cisco ISE is connected and the other domains that have user

and machine information to which you need access. For more information on establishing trust relationships,

refer to Microsoft Active Directory documentation.

+ You must have at least one global catalog server operational and accessible by Cisco ISE, in the domain to

which you are joining Cisco ISE.
