Hi all,

I've been trying to get over this configuration but without any success. I'm using freeradius-1.1.1.

First I had this working with eap-tls and peap for authentication and ldap for authorization, it was working quite well. As I have to integrate this configuration with an ldap that has encrypted passwords I decide to change authtype to pap over eap-ttls after watching Protocol and Password Compatibility in Alan's site.

The authorization part of ldap does the following:

A user will be authorized to use remote access if he is in the ldap and depending on the access policy defined if he belongs to a white or blacklist.
After being authorized within the authorize section the user find these lines:
               
                 users_branch
                 eap

user-branch is the users file I use that has entries by the form (and nothing else ):

             DEFAULT ldap11-Ldap-Group == Local
                      Tunnel-Type=VLAN,
                      Tunnel-Medium-Type=6,
                      Tunnel-Private-Group-Id=Local,
                      Fall-Through = No

This, as I said, was working right.

Now the only things I've added to radiusd.conf is

modules {
              ( I've commented any other type like chap, mschap, peap, leap... only the onse listed here are set )

              ldap-modules-stuff
              pap {
                     encryption_scheme = sha1
                    }
              eap {
                     default_eap_type = ttls
                     ...
                     gtc {
                            auth_type = PAP    # I've test without configuring gtc too and setting default_eap_type in ttls to md5 and commenting it out
                           }
                     tls {
                            my old configuration that works
                         }
                     ttls {
                            default_eap_type = gtc
                            copy_request_to_tunnel = yes
                            use_tunneled_reply = yes
                          }
                    }
              
              }


authorize {
               ...
               ldap stuff
               user_branch
               eap
              
}
authenticate {
                       Auth-Type PAP {
                                  pap
                       }
                       eap
}

                             


Then in the logs I can see that ( I don't put them because they are nearly endless ):

                     The user is authorized and the password is got from the ldap (rlm_ldap: Adding userPassword as User-Password, value {sha}rur+4yJuecpmc8vxS/8wAyAMNHM= & op=21)
                     .........
                           rad_check_password:  Found Auth-Type EAP
                           auth: type "EAP"
                    ...........
                     The eap-ttls tunnel is ok
                     ..........
                     And after matching the group Local in my users-file:

                                 auth: type Local
                                 auth: user supplied User-Password does NOT match local User-Password
                                 auth: Failed to validate the user.

                     Access-reject                
                         

When I try this with clear-text passwords it works quite well but I don't know if it is working the way I want or not (with pap), because neither with encrypted nor with clear-text I can't see in the logs a reference to rlm_pap or gtc...

I imagine I'm doing something wrong but can't figure out what it is.

I've googled on the internet and in the mailing list but I don't make any progress with what I've found.

So any comments are welcome

Thanks
