By default, the identity management feature collects information from all Kerberos servers. However, this can subject the switch to DoS attacks targeted at Kerberos servers. To reduce the opportunities for DoS attacks, you can configure a Kerberos server list for identity management. When a Kerberos server list exists, identity management collects information only from the servers in the list.
Note
Identity management supports configuration of up to 20 Kerberos servers.
