Authentication for SSH users by an LDAP server
Network requirements
As shown in Figure 16, an LDAP server is located at 10.1.1.1/24 and uses the domain name ldap.com.
Configure the switch to meet the following requirements:
• Use the LDAP server to authenticate SSH users.
• Assign the default user role network-operator to SSH users after they pass authentication.
On the LDAP server, set the administrator password to admin!123456, add user aaa, and set the user's
password to ldap!123456.
