Hi Alan,

thanks for your quick reply. I have re-look the configs and readme, and figure it out the issue why connection was not established. It was the pptp config file misconfiguration. I got the successfull connection. Then i tested with ldap authentication - configured /etc/modules/ldap section according to my ldap stuff and in sites-enabled/default enabled the ldap part. 
After that, restarted pptpd and re-run radiusd -X mode. 

itested with ldap account in localhost commandline as : 

localhost#radtest radiustest thepassword localhost 1812 testing123
Sending Access-Request of id 211 to 127.0.0.1 port 1812
User-Name = "radiustest"
User-Password = "thepassword"
NAS-IP-Address = 192.168.1.1
NAS-Port = 1812
rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=211, length=20

So this looks good, then I tried from windows machine and i get authentication failed.

As per log it mschap need cleartext password, and ldap does not store password in clear text. I do not want to integrate to windows server or samba stuff if possible. How can I achieve ldap authentication without installing samba and adding radius server into active directory ?

Khapare

 The RADIUS server is returning Access-Accept.  This means that it
thinks the user is OK.

 PPPD thinks that the PC is closing the connection.

 Not much.  Find out why the PC is closing the connection.
