This is a guide on how to connect freeradius to an ldap server.

Step 1: Install freeradius

 apt-get install freeradius 

Step 2: Modify the following freeradius configuration files:


client refers to the network that is allowed to pass Radius authentication requests such as wireless AP, L2 switch doing 802.1x, etc.

client x.x.x.x/x 
        secret = secret


user is the username. There must be one entry for each user.

user    Auth-Type := LDAP


This section is already in the file, scroll way down and modify it.

ldap {
      server = “x.x.x.x”
      identity = “cn=admin,dc=example,dc=com”
      password = password
      basedn = “dc=example,dc=com”
      filter = “(uid=%{Stripped-User-Name:-%{User-Name}})”

Step 3: Restart freeradius

/etc/init.d/freeradius restart
