I am trying to set up an LDAP server for authenticating multiple servers such as ftp and radius (maybe even ssh?)
I have a router (ddwrt) which I have been able to authenticate with plaintext passwords in freeradius. Now I want to use an ldap server to store the users and passwords
I have set up my ldap server and I can authenticate it using the following:
kevin@kevin-desktop:~$ radtest ldapuser password123 127.0.0.1 2 testing123
Sending Access-Request of id 182 to 127.0.0.1 port 1812
User-Name = "ldapuser"
User-Password = "password123"
NAS-IP-Address = 127.0.1.1
NAS-Port = 2
Message-Authenticator = 0x00000000000000000000000000000000
rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=182, length=20
But when I try to authenticate using ddwrt -> freeradius I get the following message:
rad_recv: Access-Request packet from host 192.168.11.1 port 52101, id=0, length=129
User-Name = "ldapuser"
NAS-IP-Address = 192.168.11.1
Called-Station-Id = "10da43747fcb"

You seem to have set "Auth-Type := LDAP" somewhere.
THAT CONFIGURATION IS WRONG. DELETE IT.

How do I properly set up openradius with openldap?
Best Answer
The key message here is:
I can't see an update section, but I bet that you've either set set_auth_type to yes, or that entry at line 1 of
raddb/users
has something like:For either case, you should remove the entry.
By setting Auth-Type you are forcing the server to perform a particular type of authentication which might not be suitable given the attributes in the request.
A description of how the server decides which authentication method to use is available at the RADIUS Concepts on the FreeRADIUS wiki.
For EAP authentication (which is what DD-WRT is attempting), you need to add the LDAP and PAP modules to the authorize section of
sites-available/inner-tunnel
, and ensure your Password-With-Header attribute points to the correct LDAP attribute.
