CHAP and LDAP

[Dmitry Alekhin]

Hi there,

New questions are ready. :)


I have radiusd.conf
authorize {
        chap
       preprocess
       suffix
      mschap
      ldap
}

...

authenticate {
        Auth-Type PAP {
                pap
        }
        Auth-Type LDAP {
                ldap
        }
        Auth-Type CHAP {
                chap
        }
        Auth-Type MS-CHAP {
                mschap
        }


}
...

I am making VPN server with PPPD with radius module as NAS.

Passwords are stored in LDAP database in clear text format. When i use PAP
in connection setting, it works pretty fine
( connection is established) but with chap:
What does it mean login attempt ?
